HP LTO Drive Firmware Revs For Veritas 9.1

Hi, I am an HP Customer Engineer that had to replace a Storageworks 1/8 tape autoloader (With LTO Ultrium-1 drive) for a customer running Veritas 9.1 rev 4691. It is running on a Compaq Proliant DL360 running MS Windows 2000 Server 5.00.2195 Svc Pack 4. Now it doesn't work, just hangs the SCSI bus, times out, etc.

The customer told me that he remembered the autoloader (C9572CB) had to stay at a particular older drive firmware revision in order to work, but does not remember what that version is. The original library was replaced before I got involved and I am now stuck trying to figure out which firmware the library needs to be compatible with Veritas 9.1.

This is a shot in the dark so I ran across this site and thought I'd ask this question. So do you know of any LTO /Tape Library firmware matrixes for Veritas 9.1??

I've Googled until I'm Google-eyed with no luck.. Feel free to e-mail me at: frank.petrarca@hp.com.
