Sounds VERY much like the Robot is hosed! And hence why Netbackup is having
huge, huge problems.

Contact the vendor for support on this; Assuming you are on support with
them ?

As an alternative, are you in any position to do a DSU Backups with
sufficient disk space? Just a thought.... Or another spare robotic library.

Sorry, not much help really here :-(

Subject: [Veritas-bu] Serious problem - DLT7000 tape drives gone
"notfunctional"


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:
