Mike, how is your zoning setup in the tape san environment? What model fibre 
switch  and tape library are you using?
 
You may be able to resolve the issues that you are seeing by creating a 
seperate zone for every media server that is using the SAN tape drives. So if 
you have 5 media servers create 5 zones and in each zone put the tape devices 
and one of the media servers.
 
This method has resolved many issues for me in the past where servers were 
losing tape devices in a shared tape environment.

Subject: [Veritas-bu] Losing tape drives on Windows 2003 media servers


More recently I started losing tape drives from the OS at a alarming
rate. In the past it was one here, one there, but now I am losing a few
each week on each server. I am running out of options where to go next.
I also have other Windows servers configured the same way and they never
lose drives. The server that does not lose drives is using the same
driver and all servers are using persistent binding. I did notice one
difference in the HBA driver setting. The problem servers have
"TapeResetMask" disabled. But, I would not expect that to cause this
problem. The tapes drives always remain visible in HBA Anywhere, but do
not show up in device manager. Any help would be appreciated. Thanks.
