Troubleshooting
Use the
errpt
command to identify the cause of failure. The
lsdev
command will provide the location of the component. For
example, if
errpt
identifies a loose cable on device hdisk1,
lsdev
will give an address similar to:
hdisk1 Available 00-02-01 Cambex SCSI...
and
lsattr -El hdisk1
will show:
clr_q no Device CLEARS it’s
Queue on error
location Location Label
lun_id 0x0 Logical Unit Num ID
node_name 0x20000080e511b744 FC Node Name
pvid none Physical Volume id
q_err yes Use QERR bit
q_type simple Queuing TYPE
queue_depth 16 Queue DEPTH
reassign_to 120 REASSIGN time out
rw_timeout 30 READ/WRITE timeout
scsi_id 0x0 SCSI ID
start_timeout 60 START UNIT timeout
ww_name 0x23000080e511b744 FC World Wide Name
Which indicates that the adapter is in card location 00-02, and the
drive is at SCSI ID 0, LUN 0.
