Tape changer, small issue

[Eric Anderson]

When accessing a tape changer, after moving one of the tapes to a new 
slot, I can't access the changer anymore.  A 'camcontrol rescan -v' 
makes it accessible again.

Here's what I did:




# chio status -v
picker 0:  voltag: <:0>
slot 0: <ACCESS> voltag: <:0>
[..snip..]
slot 57: <ACCESS,FULL> voltag: <000026L3:0>
portal 0: <INEAB,EXENAB,ACCESS,FULL> voltag: <000024L3:0>
portal 1: <INEAB,EXENAB,ACCESS,FULL> voltag: <000025L3:0>
drive 0: <ACCESS,FULL> voltag: <000027L3:0>
drive 1: <ACCESS> voltag: <:0>

# chio move drive 0 slot 56
(takes some time as expected)
# chio move slot 12 drive 0
(returns instantly, and I see this in /var/log/messages: isp0: command 
timed out for 0.132.0)

# chio status -v
chio: /dev/ch0: CHIOGSTATUS: Input/output error
(I try it a few more times, same issue)

Then, I do:
# camcontrol devlist -v
scbus0 on isp0 bus 0:
[..snip other devices..]
<OVERLAND NEO Series 0512>         at scbus0 target 132 lun 0 (ch0,pass6)
<HP Ultrium 3-SCSI L24H>           at scbus0 target 133 lun 0 (sa0,pass7)
<HP Ultrium 3-SCSI L24H>           at scbus0 target 134 lun 0 (sa1,pass8)
[..snip other devices..]
<  >                               at scbus0 target -1 lun -1 ()
scbus1 on isp1 bus 0:
<  >                               at scbus1 target -1 lun -1 ()
scbus-1 on xpt0 bus 0:
<  >                               at scbus-1 target -1 lun -1 (xpt0)


Now I can move tapes around again just fine.

Any ideas?

Eric
