Johan, I opened a ticket with Veritas because I had a similar problem. I
think it is related to crossroads bridges - often relabelled by StorageTek
and HP as their own.

The workaround I received is to touch the file
/usr/openv/volmgr/database/AIX_OPEN_HBA

Fixed it for me...

Hi

Master / Media server â?? Windows with Netbackup 4_5_6M
Media server â?? AIX 4.3.3 with Netbackup 4.5_6M.
2 x LTO drives that can be seen by both servers.

The AIX server can see 2 LTO drives. They are there when we do a tpautoconf
â??t and when we check for them on device monitor. They come up as TLD
control. However, as soon as a backup starts and it allocated one of the
drives, this drive disappears from the system. If you do a tpautoconf â??t,
you can only see the one drive that is not in use. If we run the â??scanâ??
command, there is only one drive and it is not the one that is being used.
The backup however continues to run. When the backup completes and we do
our scans for the drives, then both are back again. Sometimes the drive
does not come back.

Can somebody explain why this happens and how we can prevent the drives
from disappearing on AIX?
