SUMMARY: What no warm reboots?

Original question was:-


>SunManagers,

>I have an E250 running Solaris 2.6 that dies on
>'init 6' and occasionaly on 'shutdown'. It is only
>re-bootable by a power off-on cycle and ignores all
>key presses until then. Nothing out of the ordinary
in
>/var/adm/messages but, on the first occasion I ran an
>init 6 in single user mode I got:-
>failed write to utmpx entry "s6"
>failed write to utmpx entry "rb"
>and then the following message repeated
> ad-infinitum
>Warning /pci@1f, 4000/scsi3 (glm0):
>Disconnected tagged cmd(s) (1) timeout for Target 0.0


>It has a mirrored disk system and the usual patches
> - although not all are up to the most recent
> releases.


>Is this a patch problem, a dodgey disk problem or
>something completely different? Any pointers in the
>right direction gratefully accepted.

I think there may be un underlying disk stability
problem that I will look into, but the real cause 
of the hang was this lock file:-

ls -la /var/sadm/pkg/TSIgfxOW
total 22
-rw-r--r--   1 root     other          0 Jun 20  2000
!I-Lock!
drwxr-xr-x   4 root     other        512 Jun 20  2000
.
dr-xr-xr-x 315 root     sys         6656 Apr 21 14:12
..
drwxr-xr-x   2 root     other        512 Jun 20  2000
install
-rw-r--r--   1 root     other        429 Jun 20  2000
pkginfo
drwxr-xr-x   2 root     other        512 Jun 20  2000
save

This is one of the two packages that are installed to
support the Raptor GFX (sounds like something out of
Rug Rats) pci card. Special thanks to Vinnie & Julie
both of whom pointed me in the direction of suspect
graphic drivers. I'm guessing that the lock file is
generated when a driver is being installed or upgraded
and is normally removed afterwards.
