Hiya.

I have a media changer:

  install# grep ch0 /var/run/dmesg.boot 
  ch0 at isp0 bus 0 target 0 lun 1
  ch0: <HP MSL G3 Series 6.00> Removable Changer SCSI-5 device 
  ch0: 400.000MB/s transfers
  ch0: Command Queueing Enabled
  ch0: 48 slots, 2 drives, 1 picker, 0 portals

I can read status info from it:

  install# chio status | tail -8
  slot 42: <ACCESS>
  slot 43: <ACCESS>
  slot 44: <ACCESS,FULL>
  slot 45: <ACCESS>
  slot 46: <ACCESS>
  slot 47: <ACCESS,FULL>
  drive 0: <ACCESS,FULL>
  drive 1: <ACCESS,FULL>

But I can't send it commands:

  install# chio move drive 0 slot 45
  chio: /dev/ch0: CHIOMOVE: Device not configured
  install# tail -6 /var/log/messages
  Jan  2 22:05:19 install kernel: (ch0:isp0:0:0:1): MOVE MEDIUM. CDB: a5 0 0 0 0 1 4 16 0 0 0 0 
  Jan  2 22:05:19 install kernel: (ch0:isp0:0:0:1): CAM Status: SCSI Status Error
  Jan  2 22:05:19 install kernel: (ch0:isp0:0:0:1): SCSI Status: Check Condition
  Jan  2 22:05:19 install kernel: (ch0:isp0:0:0:1): ILLEGAL REQUEST asc:25,0
  Jan  2 22:05:19 install kernel: (ch0:isp0:0:0:1): Logical unit not supported
  Jan  2 22:05:19 install kernel: (ch0:isp0:0:0:1): Unretryable error

What am I missing?

Thanks.  :)
