Greetings.

Environment - Windows 2000 SP3, NBU 341 patched to 341_3A,
Compaq TLX891 Mini-Library.

I have a dire situation here where backups to a SAN-attached tape 
library are failing intermittantly. This is not the first time this problem 
has occurred, and in the past it's been because other servers have 
interfered with the hardware, and I've been able to get by it by 
disabling the tape drive and media changer devices on all those 
servers except my master/media server.

However, that isn't working this time. Ideally, I'd like to properly 
zone the library to make it invisible to everything but the master/media 
server, but that solution is prohibitively expensive and will not happen. 
So I'm looking into SCSI reserve/release as described on pages 11-18 
of patch 341_3A release notes. I can find very little general information 
about this online, and I hope someone here can fill me in.

Does Windows 2000 support this? And if so, how is it "set up properly"?
What are passthru drivers and how do I determine if they have access 
to all shared drives?
With the exception of two servers, none of the servers that can see the 
tape library has NetBackup installed. Does that make a difference?
Does the ENABLE_SCSI_RESERVE file only have to exist on the 
master/media server or all servers?

Thanks!
Lee Anne
