We are experiencing a situation where NetWorker 7.0 on Solaris fails to offline 
a device on our Scalar 1000 tape robot.
Yet at the same time if as soon as we see this happening we run an "mt -f 
/dev/rmt/0cbn offline" command the drive immediately starts to unload as it 
should have earlier.

It does this with all of the drives.
Sometimes it works but most often fails

Several complicating factors:
        The library is on a SAN (All Brocade switches)
        The tape library is an ADIC Scalar 1000 with 7 DLT8000 scsi tape drives
        The FC to SCSI routing is done with an FCR 250 (Crossroads)

Why isn't NetWorker getting the unload command to the drive (thru the NetWorker 
server HBA thru the SAN thru the FCR to the drive.

So you can see there are multiple places for the command to get lost etc.

Anyone have any ideas ?

thanks - John
