system hang at c06 after attempted install
Question:
Customer accepted offhour charge.
.ENV: AIX 3.2.4, model 550
.DESC: Customer installed the ptf U428287 but he ran out of space.
He then rebooted the system but it hang at c06.
.ACT: I had customer boot from the mksysb tape. We ran fsck on
the system. I then had him ran /usr/sbin/logform /dev/hd8,
next type "exit" to mount the filesystems.
.Had him ran "df" and the results.
hd4 1104 free 91% used
hd2 1232 free 99% used
hd3 11348 free 7% used
hd9 14884 free 9% used
.I had him ran the bosboot -a -d /dev/hdisk1, and it returned these
messages:
. cannot load program /usr/sbin/bootinfo
symbol _system _cofiguration in ksh is undefined.
error was: exec format error
/usr/bosboot 991!: test: argument expected
missing the proto type /etc/ascsidd
.I advised him to edit the /sbin/rc.boot file in line
'BOOTYPE=`bootinfo -t` to BOOTYPE=1
Had vi didn't work, terminal settings seems to be good.
\# lppchk -v -> no output
.Had him run bosboot command but same error messages.
.I had customer remove files in the /usr/lib/drivers

.We tried to run "bosboot -a -d /dev/hdisk0" but got the same
error:
. cannot load program /usr/sbin/bootinfo
symbol _system _cofiguration in ksh is undefined.
error was: exec format error
/usr/bosboot 991!: test: argument expected
bosboot: boot image is 11049 512 byte blocks
.When we tried to boot from the new boot image, the system hung at
led 554.
.Told customer that he will have to reload the system from the mksysb
Customer is going to talk to his software support and he will call
back if he needs further information.
Response:
Act: Conferenced in Jim and his customer Tom. The system is
in maintenance mode and they are having problems accessing
a non-root volume group. They want to just backup the datavg
and reinstall a mksysb since the system seems unrecoverable.
'lspv' shows 3 disks instead of 6.
hdisk0 rootvg
hdisk1 none
hdisk2 none
hdisk3,4,and5 are external disks off a different scsi
adapter and are listed as defined by 'lsdev -Cc disk'.
The disk are also mirrored as follows:
hdisk0---hdisk5 rootvg
hdisk1---hdisk3 root2vg
hdisk2---hdisk4 root2vg
Running 'exportvg root2vg' 'importvg -y root2vg hdisk1'
fails with a quorum error like it cannot access the external
drives at all.
'mkdev -l hdisk3' failed and 'cfgmgr' caused the machine to
crash after several 'unable to configure device into kernel'
errors.
We booted back into maintenance and ran diagnostics. The external
drives were not listed, although they did blink during the boot.
Running diagnostics on the scsi adapter for the external disks
returns:
"A problem was detected, a device failed to configure.
869-271 50% fuse, 45% scs1, 5% software"
'lslpp -h | grep BROKEN' finds no problems, but it could be
software related because it looks like the original installation
of the ptf U287287 did not complete.
'lppchk -v' shows several missing ptfs,
including the device driver update U427864.
hdisk0 was 100% full, so we removed hd1 (/home=2GB) and increased
/usr by 50MB since it was 99% full. Also increased /(root) to
8MB to make room to complete the installation.
Trying to install the 3.2.5 maintenance following the 'led554 fax'
failed becaue it is not on the tape. Instead we used:
ifreqs | installp -BNXacgq -d /dev/rmt0.1 -f- 2>&1 | tee /tmp/ifreqs.log
to install the missing ptfs which failed during the initial install.
Hopefully, this will solve the 'bosboot' problems and install the
drivers necessary to access the external drives.
NExt: waiting for install to complete
Response:
Act: The installp command completed successfully installing
several ptfs. After completion, the bosboot command
works. We ran:
syncvg -v rootvg
synclvodm -v rootvg
bosboot -a -d /dev/hdisk0
sync; sync; sync
shutdown -Fr
and booted in normal. This time we got a login. All disk
are listed by 'lspv' but the nonroot vg was not imported.
Ran 'importvg -y root2vg hdisk1' and 'varyonvg root2vg'
This completed, but mounts failed with:
506-324 mount failed due to format of the media
Running fsck on the root2vg logical volumes solved the
problem and they mounted successfully after that.
Next: Ran 'synclvodm -v root2vg'. Jim and Tom will recreate
a /home logical volume and restore /home from tape.
