FIX DATE DESCRIPTION
==== ======= =======================================================
1 7/8/94 PROBLEM:
The following errors occur during installation onto new
disk drives that have not been used before:
0516-796 Making hdisk0 a physical volume. Please wait.
/usr/sbin/mkvg: chdev: not found
sysrvg changed to create a vgda on the disk using chgdisk
command prior to executing the mkvg command.
When the install faile, enter maintenance mode, and type
the following command for each disk to installing on:
/etc/methods/chgdisk -l hdiskX -a pv=yes
Then reboot the system and start the install over again.
2 7/20/94 PROBLEM:
Because the filelist takes up space in /tmp after the
checking for free space, the bosboot command may fail
at the end of the install process if there is not
enough space in /tmp to build the boot image.
mkvgback command modified so as not to include any
temporary files, including the filelist, in the
volume group backup itself. Since no new files are
restored to /tmp during the install, there should be
adequate space for the bosboot to complete.
If the bosboot fails during install, enter maintenance
mode, remove all contents of the /tmp directory, and
run the "bosboot -a -d /dev/hdiskX" command. Then
exit to complete remainder of the install.
3 7/21/94 PROBLEM:
Exclude list was being ignored for non-rootvg volume
groups during a Full System Backup. Temporary exclude
list file was being erroneously removed after the
rootvg backup completed.
mkvgback command changed so as not to remove the
temporary exclude list file until all volume groups
have been backed up.
4 7/30/94 PROBLEM:
Backups to diskette did not support multiple volumes.
When reaching end of volume on diskette, the message
"Out of space writing to /dev/fd0" occured & backup
sbwrite and sbread commands enhanced to allow multiple
volumes on diskette. Prompts to change volumes without
5 7/30/94 PROBLEM:
When backing up to a disk file, default permissions
allow only owner to read the file. When performing
network installs, the sbnet user must have read
permissions to the image files.
sbwrite program will use default mask of -rw-r--r--
(0644) when creating disk files. Therefore, user need
not change permissions of files to make them available
for net installs.
Type "chmod 644 /usr/lpp/sysback/images/*" from root
before attempting network installs from disk images.
6 7/30/94 PROBLEM:
Network install failed to restore user data from
server. Error messages is: "sbinst not in /etc/services
file". Occurs because /etc/services is restored from
client image & overwrites maintenance services file.
If entry does not exist in restored services file, it
is readded before attempting to restore user volume
Continue with install, then restore the user volume
group data from the SMIT menus when system comes up.
7 8/02/94 PROBLEM:
Listing files on file/directory backup produced
error message "Invalid argument index".
Applied change to dirrestore program which was calling
incorrect message catalog number.
None. This problem does not affect the operation of the
8 8/02/94 PROBLEM:
Listing files on filesystem backup fails with syntax
error, and verifying files on filesystem backup locks
up. This only occurs when listing or restoring from a
local disk file backup.
Fix applied to jfsrestore program.
9 8/9/94 PROBLEM:
tapesvs id, used for remote backups, sometimes requires
a password be assigned, depending on OS level. Required
for use on AIX V4.1.
Changed cfgremsvs command to create a dummy password.
WORKAROUND: User may assign password using passwd command.
10 8/9/94 PROBLEM:
AIX inetserv command does not work under AIX 4.1. Used
with Sysback to configure network install server.
Changed cfginstsvr command to manually add entries to
services and inetd.conf files and refresh inetd daemon
instead of using AIX inetserv command.
Not needed on AIX 3.2 systems.
11 8/9/94 PROBLEM:
readsbheader program does not set tape block size back to
original when reading full system backup header if the
block size was different than current setting.
Changed readsbheader program to return block size when done.
User may change tape block size back to original manually.
12 8/11/94 PROBLEM:
Backup aborts when using an autoloader after the
first tape is changed. This problem occurs only after
applying fix number 4 above.
None. This was fixed prior to shipping the initial change
causing the problem.
13 8/11/94 PROBLEM:
mkvginfo locks when it encounters a volume group with
no logical volumes. This occurs when creating a full
Create a logical volume with at least 1 partition and
run the command again.
14 8/18/94 PROBLEM:
Integrated Ethernet adapter does not appear in list
of installaion devices when selecting to change install
device during install process.
Fix applied. This problem only occurred on model 250.
15 8/19/94 PROBLEM:
When installing a Full System Backup from multiple
physical devices, the block size of the secondary
(non-boot) drives are not being set properly prior
to beginning the restore.
Code existed to perform this function but was not
working properly. Fix applied.
Fix can be applied to another system, where a set of
install diskettes can be created and used to boot and
install from the original tapes where the problem
16 8/19/94 PROBLEM:
Tape drives are inadvertently rewound after reading
a parallel backup. Install process may fail to restore
data for non-rootvg volume groups.
Fix applied to sbread program to prevent rewinding of
tape drives if /dev/rmt*.1, etc used.
If install fails to restore data for non-rootvg volume
groups, the data may be restored after reboot using SMIT
option to restore files from a full system backup.
17 8/20/94 PROBLEM:
When changing LV attributes during install, the minimum
LPs for a filesystem is not accurate if user excluded
files in that filesystem from the backup. It cannot be
overridden, so there is no way to shrink or select not
to create the filesystem even if there is adequate
remaining free space.
Installation process enhanced with the following changes:
a) If user chose to exclude entire filesystem from the
backup, or if filesystem was unmounted at time of
backup, the minimum LPs will be set to 0, and user may
select to reduce or not to create without warnings.
b) Warning message appears if user attemps to change LPs
to less than minimum, but allows them to override.
c) Warning message appears if user selects not to create
a filesystem and there is not enough room in the parent
filesystem for the minimum LPs, but user may override.
d) Screen displaying logical volumes for a volume group
now shows both LPs and Minimum LPs to more easily
determine where free space may be acquired.
None. Without this enhancement, there is no way to
override the minimum LPs for a filesystem.
18 8/26/94 PROBLEM:
Performing remote backups, if user name is 8 characters,
user and hostname are concatenated when reported on the
19 8/26/94 PROBLEM:
Recreating volume groups or logical volumes from a Full
System backup via SMIT does not execute command correctly.
The device name and hostname (if any) are not being
added to the command to execute.
Fix applied. Device name, hostname and device for remote
volume prompt now appear on the SMIT screen.
Use the remakevg command from the command line instead
20 9/1/94 PROBLEM:
Recreating a volume group from a volume group or
full system backup displays the message:
"No physical volumes have been selected!" and the
Fix applied to message catalog. The program is operating
properly, but the wrong message is being displayed on
the screen from the message catalog.
Set the LANG environment variable to "C" and try again.
This will bypass the use of the erroneous message catalog.
21 9/7/94 PROBLEM:
Sysback would not allow backups to be performed to remote
tape drive if the block size of the drive was set to 0.
Removed this restriction.
None. The block size of the tape drive must have been set
to other than 0 if used as remote device.
22 9/15/94 PROBLEM:
If vdev0 is deleted, "0" is not reused for next virtual
device description as with vdev1, etc.
Fix applied. If vdev0 is deleted, next vdev created will
Edit /usr/lpp/sysback/.virdevs file and change virtual
device names manually as desired.
23 9/15/94 PROBLEM:
If space & dash ( -) entered in description field in smit
when performing backup, command fails with syntax message.
Fix applied. Dashes may be used in description field
24 9/26/94 PROBLEM:
Need to supress erorr messages regarding socket files not
being backed up.
Change applied to mkdirback and mkvgback commands so as not
to attempt to backup socket files, supressing the error
message by the backup command.
Ignore irrelevant message.
25 9/26/94 PROBLEM:
When CTRL-C used to abort backup, SMIT screen ends with OK.
Backup commands now exit with return code 1 on interrupt.
Ignore bogus return code on interrupt.
26 9/27/94 PROBLEM:
Message "The volume on - is not in backup format"
occurs when attempting to install from a network
install image, which was made in compressed format,
and a file /tmp/..header exists on the server and
is NOT owned by sbnet user.
Fix applied. This problem will be seen by few users.
On server, remove the file /tmp/..header and
restart the install.
27 9/27/94 PROBLEM:
Message "The volume group information file contains
no version information!" appears when attempting to
install from or recreate a volume group from a
full system backup.
SOLUTION: Fix applied. Only occurs if install image
is not at same level of Sysback as boot image.
None. Must install this update and create new
28 10/11/94 PROBLEM:
"cfgremtape: not found" appears when trying to list defined
remote tape devices from SMIT if /usr/sbin is not in the
Fix applied to use full pathname of command.
Either add /usr/sbin to user's path or type
"/usr/sbin/cfgremtape -l" from the command line.
29 10/20/94 PROBLEM:
Clients could log onto the server using the "tapesvs"
id with rlogin.
Change applied so that tapesvs id is created without
Use SMIT to change the "rlogin" attribute for user
"tapesvs" to "false".
30 10/21/94 PROBLEM:
Diskette drive not a valid device for full system backups
Remove diskette option from backup device list when
performing full system backup/restore/etc
31 10/28/94 PROBLEM:
Message "The volume group information file contains
no version information!" appears when attempting to
recreate a VG or LV from a full system backup.
Fix applied. Same problem as \#27, but change needed to
be applied to editvginfo program as well as remakevg.
This problem will only occur when selecting to edit
the attributes prior to recreating.
Customer may manually remove check for "$VER" in
/usr/sbin/editvginfo program or simply not select
to view or change the information prior to creating.
32 11/2/94 PROBLEM:
Message "sbread: cannot exec ttymsg!" appears during
full system install when reaching end of tape volume.
ttymsg mprogram was not being included in maintanence
mode. This program is used to display volume prompts
on the screen. The program should continue normally, but
the message to change volumes will not appear properly.
When the message appears, insert next volume. After
installing this fix, you may create and boot from
diskettes, and install fro the tape in which the error
was encountered and the problem will no longer occur.
33 11/4/94 PROBLEM:
When remaking a VG in normal mode, if a VG has no PVs
selected, the message does not appear correctly and the
Fix applied to display proper error message and require
user to select PVs for the VG.
Make sure at least one PV is selected for each VG.
If this error is encountered, CTRL-C will break out.
34 11/4/94 PROBLEM:
When backing up an unmounted filesystem using the
mklvback program, it complains that the -F (force) option
must be used to backup unmounted filesystems.
Low impact problem since mklvback is not ordinarily used
to backup filesystems. However, a fix has been applied
so that the filesystem may be backed up, either mounted
or unmounted, without complaint.
Mount the filesystem and try again.
"remakevg" command displays the message
"No physical volumes have been selected" before
attempting to recreate the VG.
This is a message catalog error. The correct message to
be displayed is "Are you sure you wish to recreate the
xxx volume group?". Message catalog ID was changed in
remakevg command to display correct message.
User may either type "y" and ENTER to continue, or
may reset the LANG environment variable to "C" and
restart the command.
36 11/14/94 PROBLEM:
editvginfo command displays negative number for amount
of disk space selected on greater than 2 GB disk drives.
Select to override the prompt that not enough space
is selected and the program will continue
37 11/14/94 PROBLEM:
The remakevg and editvginfo commands will fail on
7135 RAID, when creating the volume group and
logical volumes. Error as follows:
Making raid5vg1 volume group on disks:dac0
hdisk2 hdisk5 ..
0516-794 mkvg: dac0 is not configured. Please configure
the disk before trying this command again.
Unable to create volume group raid5vg1.
Fix applied. AIX bootinfo command supplies extra
arguments on RAID devices that must be parsed differently.
38 11/16/94 PROBLEM:
User not allowed to specify a LV size greater than
500 PPs when PP size is 4 MB and LV is used for a
filesystem. Should allow size up to 512 PPs (2 GB)
on AIX version 3 (up to 64 GB for Version 4).
Fix applied. Was incorrectly calculating maximum number
39 12/27/94 PROBLEM:
jfsrestore produces the following error message when
listing or restoring from remote backups:
/usr/sbin/jfsrestore: 0: unknown test operator
Fix applied. This does not impact operation of the program
None. This message may be ignored.
