Another thought I just got this info from one of the other postings good stuff
not my idea but might work.
"If your environment is SSO I will give you 2 tips.
Wait for the completion of all backups and then run make_scsi_dev. Then
configure all Linux drives.
After that comment (#) the make_scsi_dev line at the NetBackup startup script.
And do not reboot the system. If you do it you must run the make_scsi_dev
before netbackup start (and all drives must be idle)
I have install several linux systems and all working fine.
Smpt"

Pat,
I have 4 Linux media servers two san and two regular running SUSE9 with a
Solaris master. The san media servers seem to be doing fine as for the others
so so! I have one that crashes every time the make_scsi_dev command runs.
When NB is started by the../bin/goodies/netbackup script, it runs a
make_scsi_dev on boot that creates entries in /dev/st & /dev/sg. These
/dev/st entries are sym-links back to the /dev/nstXX device names. The problem
is it scans all scsi devices and if any are busy we get I/O errors, and if the
scsi device is in any way associated with the kernel ----down goes the
system--.
Also the trouble is that when NB is (re)started, if the tape drive is assigned
by
another media server, then the scan of the tape drives on the Linux media
server returns an I/O error for that assigned drive that the make_scsi_dev
binary interprets as a bad drive & the /dev/st link is not built. tpconfig
doesn't match & the tape daemons don't start right - not to mention that my
drive count is also wrong.
This has been a consistent problem that neither IBM nor Veritas can figure out.
We get the generic response "upgrade to the latest kernel" which is not always
going to work (Veritas storage foundation) that is another discussion.
I am still working on a solution, I think what I am going to do is create a
script to remove the /dev/st and /dev/sg devices before Netbackup starts. And
limit recycling Netbackup on the linux servers to a min.
I know this was long winded and I apologize.
Thanks
