Last night I powered on my DEC tape library. I had forgotten to power it on earlier in the week after a maintenance session. Backups to tape were queueing up. Bits needed to be moved. Queues needed to be emptied.

I powered on. I ran camcontrol rescan followed by camcontrol devlist. The tape library was not showing up. Did I manage to kill it? Did I unseat the SCSI card? After removing the system from the rack, reseating the card, trying another card, and trying another tape library, I still had no tapes.

[root@kraken ~]# camcontrol rescan 12
Re-scan of bus 12 was successful
[root@kraken ~]# camcontrol devlist | grep DEC
[root@kraken ~]# 

What was left?

The cable.

I tried a new cable:

[root@kraken ~]# camcontrol rescan 12
Re-scan of bus 12 was successful
[root@kraken ~]# camcontrol devlist | grep DEC
<DEC TL800    (C) DEC 0326>        at scbus12 target 0 lun 0 (ch0,pass12)
<DEC TZ89     (C) DEC 2561>        at scbus12 target 5 lun 0 (pass11,sa0)
[root@kraken ~]# 

WOOT!
