SAN Backup failed - backup active with error robot operation failed

[Imra_backup]

Hi fellow friends;

I have issue with SAN backup.

Component:

1. Master Server: Windows 2008R2 Server
2. Media Server: IBM AIX 7.1
3. Tape Library: Quantum i80, 4 units tape drives (LTO5)
4. SAN Switch (Brocade)
5. Veritas Netbackup v7.1

Issue:

When run backup 'policy' for Media server (IBM AIX 7.1), media keep mounting forever then got robot operation failed (status from activity monitor). This policy configure to use storage unit define to backup through SAN network.

If run backup for other client & using different storage unit, backup running OK and normally ended up status=0,  completed.

In summary: can conclude backup over SAN not OK while backup through LAN network is OK.

Appreciated advice/comments/recommendation. Thank you in Advance..

I have cleared the solution - this post is NOT the solution!!!

two things. 1. have you check if there is a tape in the drive. check it with robot panel or robtest. robtest must run from the robot control host. 2 check the cleaning remaining s number of your cleaning tape. If the number is 0 or if there is no cleaning tape, clean the drive manualy with a new cleaning tape.

Imra - you will agree with me that OS restart did the same as per my suggestion on 30 January?

Try to remove and recreate devices at OS level. Work with your AIX sysadmin.

o rmdev -dl rmtx

o rmdev -dl smcx
o cfgmgr -v
o lsdev -Cc tape

This was never done at the time, right?
