[Veritas-bu] Serious problem - DLT7000 tape drives gone "not functional"

Hello all,

We're running a Solaris w/ NetBackup 5.0 master server environment with 
a SCSI attached StorageTek L700 library with eight DLT7000 drives.  We 
ran into an "event" the other night which cleared the L700 configuration 
which reset all of the drive SCSI ID's to Invalid.  I manually 
reconfigured the SCSI ID's 00 through 08 (skipping 07 which we cannot 
use).  SGSCAN sees the drives but when I try robtest or run manual 
backups the environment goes crazy and DOWN's all the drives.  I've got 
a support ticket opened with StorageTek but at this point they're not 
sure what the problem could be.  The LCD display on the L700 library 
says "NOT FUNCTIONAL" for all the drives even after a reboot.

Here's some information from sgscan / tpconfig && robtest:
