Ah yes, the patch cluster problem.  I've seen this before as well and it's a
result of the patch cluster overwriting configuration files with a default
one.  It's depends on exactly what patches are part of the cluster but I've
seen the sd.conf and st.conf files effected in the past.  Yes, this is just
plain stupid on the part of Sun but I digress... I suggest you scower your
conf files in /etc and /kernel/drv to make sure they are correct.  In the
future, save *.conf in /etc and /kernel/drv.

Subject: [Veritas-bu] Tape drives keep going down upon use on Solaris 8
master server after upgrade


Hi, last week, I configured my drives from the OS (solaris 8) through NBU
(datacenter) and everything was happy. Yesterday, I installed the most
recent 8_Recommended patch set. Everything looked OK and I left it. Today, I
notice that the drives go down every time I try to use them through NBU.
When I kick off a job, I get this error:
Aug 28 14:41:29 backup1.dmc.org avrd[1912]: Fatal open error on
IBMULTRIUM-TD13
(device 1, /dev/rmt/5cbn), errno = 6 (No such device or address), DOWN'ing
it

If I drop to the OS level, the drives are there just as they should be
(/dev/rmt entries pointing to /devices/... entries. I have also noticed
this:
# mt -f /dev/rmt/0 status
/dev/rmt/0: No such device or address

But, if I do a reconfig reboot the drives are put back in their normal
place, and n sgscan sees the drives where I would expect it to.

This problems was occuring beforehand, but I did also upgrade from NBU
datacenter 4.5GA to 4.5 MP5 today.

Any thoughts? I am stuck and our backups are dead in the water.
