I have a 3583 library connected through SCSI to a 4500R IBM server. I
recently updated the firmware (22U0 on the drives and V2_72_12.lif)  on
the drives and the library. When I finished the library would not accept
commands. I can query the drives and they are on-line and I can query the
library. Does anyone have any suggestion on what the problem could be? TSM
only sees two of my 6 drives, I have checked my connections.

Thanks,
