We are having some issue accessing any of the tapes on the device. I issued a "omnisv stop" and "omnisv start" command while the device was in the process of backing up a file. When I then later brought up the data protector GUI I noticed that slot 7 was showing as being empty. This was the slot that the tape was in that was being used at that point in time.
I was able to get the tape back into the slot using the menu on the physical device. Now none of my backups want to work and I am not able to format any new tape that I insert into the device.
Now I am getting a "[90:54] Cannot open device (/dev/rtape/tape2_BESTn)" error message. It almost feels like the software thinks there is still a tape in use.
"I did "devbra -devices" and got nothing on the screen."
I don't know if 'devbra -devices' will give the same output as 'devbra -dev', which is how the command should be run
Assuming that the output is accurate, this means that DP sees no locally-attached devices (Devices in a SAN are considered to be Locally Attached), you will need to reboot the HPUX media agent, which descovers all locally-attached devices, and run 'devbra -dev' again
As a last attempt before calling support I looked at the unix side of the equation and found that I had a session running on one of the hosts. I then killed the session and I was able to format tapes again.
ps -ef | grep omni
kill -9 nnnnn
Thanks to everybody for their help and suggestions.
