Thanks again to everyone who contributed, I apologize to those whom I
can not reply to directly. Please spread the word about FAQs in
general. There is a FAQ for most of the usenet newsgroups and every
FAQ posted to news.answered is archived at rtfm.mit.edu and it's
mirrors.
Frequently Asked Questions about AIX and the IBM RS/6000 Section 1
__________________________________________________________________
This posting contains frequently asked questions and answers about the
IBM RS/6000 series workstations and AIX version 3. All input is very
welcome, I can be reached at jwarring@aol.net.
The list is split into four articles to pass thru most mailers. I'll
usually try to post them once a month to comp.unix.aix, news.answers,
and comp.answers. Please let your input continue as I am most thankful
for all of it.
Please make a note of the fact that these sites contain more than just
the AIX FAQ and would probably be worth consulting before you post
questions to any of the usenet groups.
If you see a From: line it means that whatever follows is either an
unabridged or slightly edited version of the input I have received, and
that I may not have verified its contents. If there is no From: line, I
probably know what I am talking about, and the entry is edited from
various sources.
All entries are numbered with major and minor subject number, e.g.
2.11. If the subject is preceded by an asterisk, that entry has been
changed or added since the last posting.
The comp.unix.aix group is for AIX on all IBM platforms -- RT, PS/2,
370, RS/6000 and mainframes (ESA based on OSF/1), but the traffic has
evolved to discuss predominantly AIX 3.x and the RS/6000. The
newsgroups comp.sys.ibm.pc.rt and comp.sys.ibm.ps2.hardware cover the
RT, mostly hardware and AOS 4.3, and on PS/2 hardware respectively.
Mark Whetzel posts FAQ lists about RTs in the rt and *.answers groups.
There are few to non-existent discussions on AIX/370 and AIX/ESA.
This article covers only AIX 3.x and the RS/6000, except when noted.
If you post questions to comp.unix.aix, please be sure to indicate:
- the machine type and brief configuration, e.g. Model 540, 64 MB RAM,
48 MB swap space (this is actually bad), 1.2 GB XYZ hard drive, etc.
Note: There are now three classes of RS/6000s - the original, RS or
POWER, RS/2 or POWER2, and PowerPC.
- the exact AIX version number, i.e. AIX 3.1 is NOT sufficient, whereas
AIX 3.1.5 or AIX 3.1 with the 3005 update is. With 3.2 you should
mention any significant ptfs using the U4xxxxx numbers.
I am doing this on my own time. Please do not ask me questions that
should be asked to IBM. If you suspect you have software defect problems
call (800) 237-5511. If you have hardware problems call (800) IBM-SERV.

______________________________________________________________________________
1.000: The AIX operating system - what is it?
This is best answered by reading the text files in /usr/lpp/bos. The
README file there contains general information and the bsd file contain
useful information if you know BSD and/or System V.
The last release for the RT PC is 2.2.1. The latest release for PS/2s
and Intel architecture machines is AIX 1.3; for PS/2s only, 1.2.1. For
the RS/6000, there are three major levels, 3.1, 3.2, 4.1, and various
intermediate levels. IBM has dropped support for 3.1.
For those who don't have a copy of /usr/lpp/bos/README or bsd, I'll
sumarize: IBM tried to follow IEEE, POSIX 1003.1, ANSI C, FIPS and
then X/Open Issue 3. Beyond that, AIX is a combination of System V
and BSD.
1.001: I know neither Unix nor AIX - where do I find more information?
If you are new to Unix, you should look at the other newsgroups in the
comp.unix hierarchy, in particular comp.unix.questions. There are
FAQs more most of these groups as well.
If you need information about C programming, try comp.lang.c or
comp.std.c, the latter for Standard ANSI C issues. comp.lang.c has a
FAQ posting.
1.002: What is the Object Database?
From: Uwe Geuder <Uwe.Geuder@informatik.uni-stuttgart.de>
AIX stores most of the system management information in /etc/objrepos,
/usr/lib/objrepos, and /usr/share/lib/objrepos. Files (also referred to
as system object classes) in these directories are adminstered by the
Object Database Manager, ODM, which is a set of library routines and
programs providing basic object oriented database facilities.
Under most circumstances, only SMIT or the commands SMIT call (see
1.100) should be used to change the contents of the system object
classes. A harmless way to look at the object database is to use odmget
<Class> where <Class> is one of the files in /etc/objrepos.
Experienced users can use the ODM editor, odme, to navigate the database
in detail. Modifying the database should only be attempted if you know
exactly what you are doing.
1.003: How do I get rid of the verbose error messages?
Corrected by Bjorn P. Brox <brox@corena.n>
Many of the messages from the Unix commands are available in different
languages. This is controlled by the LANG environment variable, the
default being En_US meaning English in the US. All the default messages
have a message number associated with them, e.g.:
$ cat no-such-file
cat: 0652-050 Cannot open no-such-file.
If you prefer the terser Unix-looking error message, set your
environment variable LC_MESSAGES to C, and you will get:
$ cat no-such-file
cat: Cannot open no-such-file.
By default LC_MESSAGES is the same as your environment LANG. Setting
LANG does also work, but should be avoided since it changes
app-defaults lookup etc. See locale(): LC_ALL
1.004: Which release of AIX or other products do I have?
New with 3.2.5: The oslevel command shows OS and component levels.
Run oslevel -help to see options
The command 'lslpp -h bos.obj' will show all lines referring to the BOS,
Basic Operating System. E.g.:
Fix Id Release Status Action Date Time User Name
------- --------------- --------- ---------- ---------- -------- ---------
Path: /usr/lib/objrepos
bos.obj

U419950 03.02.0000.0000 COMPLETE COMMIT 08/28/93 15:34:11 root
For AIX 3.2, you may come across discussions on 3.2.0, 3.2.1, 3.2.2,
3.2.3 extended, 3.2.4 and 3.2.5. There is no absolute way to tell which
of these you are running since the newer releases are simply 3.2.0 with
some sets of PTFs added. See above example listing. These selective
fixes could mean there are literally thousands of slightly different
variations of 3.2 in use. Please see section 6 to request some useful
faxes to help with this number game.
AIX 3.2.4 and later attempts to resolve this confusion. The OS is
broken down into subsystems so that updates can be applied to an entire
subsystem. lslpp also sports a new option; use 'lslpp -m bos.obj' to
show what level and update the system is running. You can also use the
new oslevel command. Unless you have a pressing need (such as
applications unsupported on > 3.2.3), it is recommended that you update
to this level. Also see 1.128.

1.100: I am used to Unix systems programming, why should I learn SMIT?
Using SMIT is probably very different from your normal way of doing
system administration, but could prove very useful in the long run. In
some areas, in particular TCP/IP, NFS, etc., you can also do things the
normal way, but it is unfortunately difficult to know exactly when the
normal way works. Again, always using SMIT is probably your best way
to go, even when you have to learn a new tool.
What SMIT actually does is build up commands with all required options
to perform the functions requested and execute them. The commands
called and the output they produce are stored in the files smit.script
and smit.log in your home directory. Looking in smit.script may teach
you more about system administration.
1.101: How do I turn off the "running man" in smit?
Use smitty, the standard curses version or add this line to your .kshrc file:
alias smit="smit -C"
1.102: How do I import an /etc/passwd or /etc/group file from another box?
Make sure that you run usrck, pwdck (/etc/passwd), and grpck
(/etc/group) to let AIX work its password/group magic.
1.103: Cleaning up utmp, who, and accounting problems
From: fritz@scipp.UCSC.EDU (Frederick Staats)
This applies if you are running an X11R5 xterm on 3.2.
Add this to the top of X11R5 mit/clients/xterm/main.c:
#ifdef AIXV3
#define USE_SYSV_UTMP
#define HAS_UTMP_UT_HOST
#define WTMP_FILENAME "/var/adm/wtmp"
#endif
And your utmp problems should go away. If you want xterminal sessions
to go into the wtmp file you need to define -DWTMP in the Imakefile and
be sure the WTMP_FILENAME is set to the right place.
The following program by jfh@rpp386.cactus.org (John F. Haugh)
if run in the background by root will clean up the utmp file.
#include <sys/types.h>
#include <utmp.h>
#include <fcntl.h>
main ()
{
int fd;
struct utmp utmp;
while (1) {
if ((fd = open ("/etc/utmp", O_RDWR)) < 0)
exit (1);
while (read (fd, &utmp, sizeof utmp) == sizeof utmp) {
if (utmp.ut_type == USER_PROCESS &&
kill (utmp.ut_pid, 0) != 0) {
lseek (fd, - (long) sizeof utmp, 1);
utmp.ut_type = DEAD_PROCESS;
write (fd, &utmp, sizeof utmp);
}
}
close (fd);
sleep (60);
}
}
Another utmp program was posted to comp.sources.unix, volume 25, issue
96 by David W. Sanderson (dws@cs.wisc.edu) that also works on AIX 3.1.
1.104: How to fsck the root filesystem
You can run fsck either in maintenance mode or on mounted filesystems.
Try this:
1. boot from diskette
2. select maintenance mode
3. type /etc/continue hdisk0 exit (replace hdisk0 with boot disk if
not hdisk0)
4. fsck /dev/hd4
1.105: How can I unmount /usr to run fsck on it?
From: accapadi@mathew.austin.ibm.com (Matt Accapadi)
[ This is for 3.2. ]
In order to fsck /usr, it has to be unmounted. But /usr cannot be
unmounted because /bin is symbolically linked to /usr/bin. Also
/etc/fsck is symbolically linked to /usr/sbin/fsck.
To work around this, when you boot from the boot/maintenance diskettes
and enter maintenance mode, enter "getrootfs hdisk0 sh" instead of
"getrootfs hdisk0" where hdisk0 is the name of the boot disk. Then run
"fsck /dev/hd2".
1.108: How do I see/change parameters like number of processes per user?
You can use SMIT as described below or simply use lsattr/chdev.
The former will list the current setting as in:
# lsattr -E -l sys0 -a maxuproc
maxuproc 40 Maximum # of processes allowed per user True
and you can then increase the maxuproc parameter:
# chdev -l sys0 -a maxuproc=200
sys0 changed
If you just type 'lsattr -E -l sys0' you will get a list of all
parameters, some of which can be changed but not others.
If you want to use smit, do as follows:
smit
System Environments and Processes
Change / Show Operating System Parameters
- on this screen you can change by overtyping the following fields:
- Maximum number of PROCESSES allowed per user
- Maximum number of pages in block I/O BUFFER CACHE
- Maximum Kbytes of real memory allowed for MBUFS
- toggle fields exist for:
- Automatically REBOOT system after a crash (false/true)
- Continuously maintain DISK I/O history (true/false)
Info 1.30 erroneously suggests that in AIX 3.2.5 you can set different
limits for different users.
1.109: How do I shrink the default paging space on hd6?
1) create a paging space to use temporarily
mkps -s 20 -a rootvg
2) change default paging space hd6 so it is not used at next reboot
chps -a n hd6
3) For AIX 3.1, edit /etc/rc.boot4 and change swapon /dev/hd6;
for AIX 3.2, edit /sbin/rc.boot and change swapon /dev/hd6
swapon /dev/paging00
4) Update information in boot logical volume
bosboot -a (3.1)
bosboot -a -d hdisk0 (3.2)
5) shutdown and reboot
6) remove current hd6 and create a new one of smaller size
rmps hd6
mklv -y hd6 -t paging rootvg <size of PS in 4 Meg blocks>
7) Re-edit /etc/rc.boot4 (3.1), /sbin/rc.boot (3.2) to swap to /dev/hd6
swapon /dev/hd6
8) Update information in boot logical volume
bosboot -a (3.1)
bosboot -a -d hdisk0 (3.2)
9) change current paging device (paging00) so it is inactive at next boot
v chps -a n /dev/paging00
10) shutdown, reboot, remove paging00 using the command:
rmps paging00
You can check your paging space with `lsps -a`
1.110: The swapper seems to use enormous amounts of paging space, why?
When you run ps, you may see a line like:
USER PID %CPU %MEM SZ RSS TT STAT TIME CMD
root 0 0.0% 14% 386528 8688 - S 17:06 swapper
This is normal behavior, the swapper looks to ps like it has the entire
paging space plus real memory allocated.
1.111: How much paging space do I need?
See answer 2 in question 1.300.
1.112: How do I mount a floppy disk as a filesystem?
From: op@holmes.acc.Virginia.EDU (Olaf Pors)
You can build a filesystem on a floppy and mount it, however the
filesystem will be read only. The reason that the filesystem will be
read only is because AIX Version 3.1.5 cannot create a journal log on a
diskette. The intended use is for temporary access to read only data.
The diskette file system must be unmounted after use and during system
backup procedures or errors could occur.
To make the read only filesystem on a floppy:
1. Make a subdirectory on an existing filesystem and place all of the
files that the diskette will contain into this subdirectory.
2. Enter the following command to create a prototype file containing
information about the new filesystem, in the example /dir_struct
is the pathname of the subdirectory created in step 1, and
proto_filename is the name of the prototype file to be created.
proto /dir_struct > proto_filename
3. Place a formatted floppy into the drive.
4. Edit the prototype file and replace the first line with the following:
<noboot> 0 0
5. Enter the following command to make the filesystem on your floppy:
mkfs -p proto_filename -V jfs /dev/fd0
6. Create the directory upon which you will mount the floppy based
filesystem, or you can use /mnt. Mount the filesystem:
mount -r -V jfs /dev/fd0 /your_mount_point
7. To unmount the filesystem:
umount /dev/fd0
Since the filesystem is read-only it may be of limited use but if you
are going to use it for utility programs and other data that does not
change much, it may still be useful. If you need to change the data,
you can copy the directory from the floppy into another directory, make
your modifications, and remake the filesystem using this procedure.
1.113: How do I remove a committed lpp?
You can get rid of COMMITTED lpps/ptfs by installing with the force
option and then rejecting the package.
AIX 4.1 users: installp has a new option, uninstall (-u) which can be
used to remove lpps.
1.114: How can I recover space after installing updates?
From: Milt Cloud <cloud@ux1.cso.uiuc.edu>
Note: If you are a /usr server, do not use this because the files
mentioned below are needed by /usr clients and cannot be deleted.
Installp creates numerous files in /usr to clean up after
failed/rejected installs and also for de-installing uncommitted lpps.
Once you have COMMITted packages you can remove these files safely.
Depending on your installation activity the numbers can be significant:
hundreds-to-thousands of files, megabytes of data.
Files eligible for removal are associated with each "product" you have
installed; the largest collection being due to bos. After
COMMITting bos lpps, you may safely remove all files of the form:
/usr/lpp/bos/deinstl*
/usr/lpp/bos/inst_U4*
/usr/lpp/bosadt/deinstl*
and /usr/lpp/bosadt/inst_U4*
You may repeat this for all additional COMMITted products (e.g.,
bostext1, bosnet, xlc) you have on your system.
This problem of lingering install files is a known defect in installp.
If you have installed PTF U411711 (or any superseder of it: U412397,
U413366, U413425) the deadwood in /usr will not be quite as prevalent.
No single PTF currently available completely corrects this problem.
On my own 320, the following freed up 12.4M in /usr:
# rm -R /usr/lpp/bos/deinstl*
# rm -R /usr/lpp/bos/inst_U4*
1.115: Where are the AIX log files kept?
From: dirk@kimosabi.ucsc.edu (Dirk Coldewey)
AIX logs messages as specified in /etc/syslog.conf. Here's an
example
#
*.err;kern.debug;auth.notice;user.none /dev/console
*.err;kern.debug;daemon,auth.notice;mail.crit;user.none /var/adm/messages
lpr.debug /var/adm/lpd-errs
*.alert;kern.err;daemon.err;user.none operator
*.alert;user.none root
*.emerg;user.none *
# for loghost machines, to have authentication messages (su, login, etc.)
# logged to a file, un-comment out the following line and adjust the
# file name as appropriate.
#
# if a non-loghost machine chooses to have such messages

1.116: How can I log information about ftp accesses to a file?
From: elr@trintex.uucp (Ed Ravin) and
map@hal.maths.monash.edu.au (Michael Page)
1) In /etc/syslog.conf, add the line:
daemon.debug /tmp/daemon.log
2) # touch /tmp/daemon.log
# refresh -s syslogd
3) Modify your inetd.conf so that ftpd is called with the "-l" flag.
You may also want the "-d" flag. This can be done with 'smit inetdconf'.
All the syslog messages from various system daemons should now appear in
the file "/tmp/daemon.log".
1.117: How do I find a file name from the inode number?
From: svpillay@berlioz.crs4.it (Kanthan Pillay)
find /mntpoint -xdev -inum nnnn -print
1.118: How do I set up postscript accounting?
From: taluskie@utpapa.ph.utexas.edu (Vince Taluskie)
Ephraim Vider originally wrote this program to configure postscript page
accounting. It acts as a backend wrapper which logs accounting
information in /etc/qconfig and can be ftp'd from utpapa.ph.utexas.edu
in /pub/aix/psacct.tar.Z.
Compile with:
cc pswrap.c -o pswrap -lqb
and then make this program suid root:
chown root pswrap
chmod u+s pswrap
If this step is not done, the printer will hang.
Then start up SMIT and go to :
Spooler
Manage Local Printer Subsystem
Local Printer Queue Devices
Change / Show Characteristics of a Queue Device
<Select Queue>
<Select Device>
and change "BACKEND PROGRAM pathname" to the full pathname of pswrap
since pswrap will now handle the backend interface with the queue.
A stream of info will be written to a logfile in /tmp (prob lp0.log) but
this file is mainly used for status info and raw pagecounts. If the
accounting data is going to the qconfig-specified acctfile, then use the
'pac' command to read it. I prefer to have readable ascii data files
instead, so I just comment out the '#define WANT_PAC' line and it will
only go to the ACCTFILE specfied in pswrap.c.
/* pswrap.c
compile with: cc pswrap.c -o pswrap -lqb
(for doc on the qb library see "understanding backend routines in libqb")
BTW: The log_charge() function doesn't seem to do anything,
but log_pages() updates the accounting info.
Ephraim Vider, original author
--
Feb 10, 1993
You can set pswrap up to use either the accounting file specified in
/etc/qconfig (which means that you need to get your data from 'pac') or
you can comment out the #define WANT_PAC line and then the accounting
data will only go into the ACCTFILE.
Also modified the logging to the ASCII acctfile so that it looks more
readable.

1.119: How do I create boot diskettes for 3.2?
You need to have four formatted diskettes.
boot disk: bosboot -d /dev/fd0 -a
display disk: mkdispdskt
display extension disk: mkextdskt
Install/Maintenance disk: mkinstdskt
1.120: Where can I find tools for performance monitoring?
Free X based performance watcher: xsysstats - ftp site ftp.x.org:/contrib
For 3.2 a few tools are available in /usr/lpp/bosperf. There are tools
to monitor traces, I/O events, CPU, virtual memory, disk block usage,
kernel extensions, etc. It even has a simulator, rmss, that allows one
to try out different memory size configurations to see how it impacts
performance. See 6.05 for the AIX Performance and Tuning Guide.
Monitor is an excellent tty based program that includes:
- cpu usage
- load average (from kernel or by using loadavgd program)
- virtual and real memory usage
- paging information
- process events
- Disk I/O (summary and TOP disks 1.12)
- TTY I/O
- Network activity
- top cpu users
- NFS operations (New to 1.11)
- more detailed disk I/O screen (New to 1.11 with -disk option)
- more detailed network I/O screen (New to 1.12 with -net option)
- toggle between normal/top/net/disk display using t,n,d keys
Monitor is available from
ftp.funet.fi:pub/unix/AIX/RS6000/monitor-1.11.tar.Z
1.121: How can I tell what virtual printer a print queue is using?
From: yoder@austin.ibm.com (Stuart R. Yoder)
Use the command 'lsvirprt'. Don't use any parameters and it will
run in an interactive mode that will give you a menu of all virtual
printers on the system with the queue and device for each one.
1.122: Two srcmstr's are less useful than one?
From: hubert@rs530.ncs.mainz.ibm.com (Bernhard Zeller)
This can happen on systems that have no console, or systems with an
async terminal as the console but not attached or turned off. One of the
symptoms is a second srcmstr got run. But the second srcmstr is worthless
as we can't use the stop/startsrc commands, refresh inetd, qdaemon won't
start, etc.
To resolve this, type:
smit chgtty
and add the keyword 'clocal' in following lines:
STTY attributes for RUN TIME
STTY attributes for LOGIN
1.123: How do I set the tty name associated with a physical port?
From: accapadi@mathew.austin.ibm.com (Matt Accapadi)
Let's say you wanted to make a tty on the s1 port and call it rs0000
and a tty on the s2 port and call it rs0001.
You could run:
mkdev -c tty -s rs232 -t tty -l rs0000 -p sa0 -w s1 # creates rs0000
and
mkdev -c tty -s rs232 -t tty -l rs0001 -p sa1 -w s2 # creates rs0001
1.124: How do I use mksysb to clone a system?
From: joann@ariadne.SLAC.Stanford.EDU (Jo Ann Malina)
I use the following steps on the master machine to clone an AIX system:
1) Remove the password from root.
2) Remove the NIS line from the end of the /etc/group file (the last
line with the +: )
3) Change most of the level '2' designations in /etc/inittab to level
'3' to prevent them from being started up when the new system is
booted (the minimum ones to change are rc.nfs and rc.tcpip)
4) Boot in service mode and change the name and ip address to a "spare"
set to avoid address collision.
5) Clear /tmp, /usr/tmp and /usr/spool/lpd/stat.
6) Run mkszfile and edit it to be sure /usr is as small as possible;
then mksysb from the command line.
The above changes allow me to boot in normal mode the first time, get in
as root, change the above files back and do the other things necessary
to configure the new system.
Then, of course, I go back and clean up and reboot my master machine.
Note: 1 and 2 lets you log in even if you can't get on the network.
It prevents the login process from trying to reach an NIS server.
Step 2 needed only if you use NIS.
1.125: How do I retain timestamps with mksysb?
Originally From: graeme@ccu1.aukuni.ac.nz ( Graeme Moffat)
As of AIX 3.2.5 bosrest preserves timestamps and permissions as does pax.
In AIX 3.2.2 /usr/lpp/bosinst/bosnet (for net installs), and bosrest
(tape), the 'pax' commands all have '-pmop' options. m = "DON'T
retain modification times". So, simply change all the '-pmop' to
'-pop' and remake inst/maint diskettes or mksysb tapes.

1.128: AIX fix strategy
From: leedp@austin.ibm.com (Dennis Lee, PMP Release Manager)
First, a little history...
The maintenance strategy for AIX 3.1 was cumulative updates. Every few
months, we'd put all available fixes in one large package and ship it.
There was no real strategy for providing a single fix. Although we'd
occasionally produce an emergency patch, there was no method for
tracking them; if you got a second one, it might overwrite the first.
So, after a few of these patches, it's hard to track.
In AIX 3.2 we introduced a "selective fix" strategy to support
individual fixes. The package contained information about other fixes
that were required for that fix to work correctly. For example, a Korn
shell fix might require a change in libc.a, which might in turn require
a fix in the kernel. This strategy allowed us to keep track of which
fixes were installed to make sure we didn't overwrite one with another,
and make sure they all worked together. But the initial selective fix
design still had a few problems.
o None of the fixes were cumulative. If you got a fix for Korn shell,
you may not receive all of the fixes for Korn shell. This left the
possibility of rediscovering other problems that were already fixed.
o Since we chose to fix everything possible that was reported as a
problem, instead of deferring them to the next release, the number
of available fixes became quite large.
o The number of additional fixes required by any given fix could also
be quite large. Since the installation program ran once for each
fix, the size and complexity of the fix packages grew, and
installation time lengthens greatly.
While developing the AIX 3.2.4 upgrade, we undertook a large effort to
resolve the selective fix concerns, and dramatically increase the
quality of AIX 3.2. The base operating system and most of the optional
program products were split into subsystems. A subsystem is a group of
logically related files. The division was made such that changes to a
given subsystem were less likely to affect other subsystems. In total
there are approximately 500 subsystems, but in practice, files have been
modified in only about half of them. The advantages of the new
packaging strategy are:
o Each subsystem package is cumulative, containing all of the fixes
and enhancements to date for that subsystem.
o The cumulative subsystem package is tested as an entity.
o The number of fix packages is greatly reduced because the number of
subsystems is far fewer than the number of fixes and enhancements.
o The number of other fixes required by any given fix is also greatly
reduced because a subsystem package has requisites only on other
subsystem packages.
o The reduced number of fix packages greatly reduced installation time.
Some customers also told us that they liked the maintenance level
strategy that we used in AIX 3.1. They liked being able to install all
of the known fixes, and they liked knowing what "level" of AIX they had.
To meet these requirements, we produced a Preventive Maintenance Package
(PMP). The PMP is simply a collection of the latest cumulative
subsystem packages tied together in such a way that it can be installed
by selecting a single fix. We also added flags to the lslpp command and
added a new command, oslevel, to show which PMP is installed. Now we
had both! The good attributes of selective fix along with the good
attributes of maintenance levels.
A few Q&As:
Q. Why is the fix I just received 130 megabytes!@#? I already have the
AIX 3.2.4 update installed!
A. Your fix may be part of the AIX 3.2.5 update. AIX 3.2.5 is another
PMP that contains all of the fixes to date, as well as enhancements
to support the PowerPC model 250, and the new high-end RS/2 models
590 and 990, as well as support for new disk and tape drives, graphics
adapters and more.
Q. Why can't you just build my fix on 3.2.4?
A. There really isn't such a thing as 3.2.1 or 3.2.2 or even 3.2.4.
They're just collections of fixes and enhancements built on a 3.2 base.
If the fix for your problem was built prior to 3.2.5, you can get the
older version. But if your fix was built for the first time in a 3.2.5
subsystem, that's the only version of the fix that exists.
See also 6.02.
1.129: Are passwords limited to 8 char?
AIX passwords are only significant to 8 characters. You can set a
passwd to more than 8 characters but anything over eight are ignored.
No messages or warnings are given.
Be careful if you're running NIS. You probably want to limit passwords
to 8 char on all machines (6000 and others) to be compatible.
Someone mentioned that DCE supports kerberos which supports passwords
greater than 8 characters.
1.130: How do I increase the number of ptys > 64?
From: mick@oahu.cern.ch (Mickey Coggins)
SMIT only allows 64. Try this:
odmget -q"attribute=num and uniquetype=pty/pty/pty" PdAt |
sed "s/0-64/0-512/" |
odmchange -q"attribute=num and uniquetype=pty/pty/pty" -o PdAt
chdev -l pty0 -anum=256 -P
reboot

1.132: How do I remove a non-existant physical volume?
Thanks to Johnny Shieh (shieh@austin.ibm.com)
To delete a phantom disk from the ODM use reducevg with the pvid
instead of the disk name. You are running some command such as lsvg
or varyonvg and it is griping about a disk that is no longer findable
right? In that warning message, it should give you a pvid. Try one
of the following, (note: reducevg updates the VGDA but not the ODM).
reducevg -f <vgname> <pvid>
ldeletepv -g VGid -p PVid
-g Required, specify the VGid of the volume group you are
removing the physical volume from
-p Required, specify the PVid of the PV to be removed
1.133 How do I kill a process that ignores kill -QUIT -KILL -STOP
If there is i/o pending in a device driver, and the driver does not
catch the signal, you can't kill it - a reboot is the only way to
clear it.
Furthermore, if the process stays hung for more than a few minutes,
you can find out what device is wedged by doing this --
% echo trace -k $(expr <pid> / 256) | crash | tee stack
If you can't figure out what is wrong, print that trace out and call
1-800-237-5511 and tell them that something is broken. Tell them you
want to fax in the nice stack trace that you have as your testcase.
1.134: How can I see "console" messages?
From: crow@tivoli.com (David L. Crow)
Use the swcons command to redirect the console to a file. Or use
chcons to do it permanently.
1.135: Where can I find TOP for AIX?
TOP functionality is included in an AIX package called Monitor
availible from aixpdslib.seas.ucla.edu:/pub/monitor among other
places.
1.136: How can I restrict root logins to specific terminals?
From: jfh@austin.ibm.com (John F. Haugh II)
Read FAX 2737 availible from the 800-IBM-4FAX number discussed in
section 6.02. Refer to APAR IX45701 for fixes related to the rsh style
commands.
1.137: How do I merge my /etc/password and /etc/security/password for Crack
/usr/sbin/mrgpwd. You must have permissions to read /etc/security/password.
1.138: I lost the root password, what should I do?
(From: [a posting by] dramm@csusm.edu (Donald E. Ramm))
Boot from boot diskettes, bootable tape, or bootable CD.
At the Installation/Maint menu select item 4, "Start a limited function
maintenance shell.
At the subsequent "#" prompt enter the command:
getrootfs hdiskN
(where "N" is replaced by the number of a disk on your system
that is in rootvg.)
That will run for about a minute or so and you get a # prompt back. At this
point you are logged in as root in single user mode.
Change to /etc/security and edit the passwd file. Delete the three lines
under root: password, update time (or whatever it's called), and
flags. Save the file.
Then at the prompt, give root a new password.
Shutdown/reboot in normal mode. Log in with new password.
1.139: How can I resolve DEV_WAIT status for a local print queue?

1.142: How can I get PTF (fixes) via ftp? What is fixdist?
Get a copy of IBM's fixdist package. This X-windows program can help
you find and transfer PTFs from IBM to your machine. It is availible
from <URL:ftp://aix.boulder.ibm.com>/ and further instructions are
displayed after you login. It is worth noting here that the files
fixdist retrieves are often quite large and therefore not recommended
for those with slow connections.
