Path priority number
This number indicates the priority level set for each path. Priority levels can be
set from
1
to
255
. The lower the number, the higher the priority. The default is
1
.
The priority level is set by using OS commands. The following shows an example
of the procedure for setting the path priority number.
1.
Execute a command that displays the path information for the LU:
# lspath -l hdisk4 -F"name parent path_id connection
path_status status"
hdisk4 fscsi0 0 50060e8005271720,31000000000000
Available Enabled
hdisk4 fscsi1 1 50060e8005271730,31000000000000
Available Enabled
hdisk4 fscsi2 2 50060e8005271740,31000000000000
Available Enabled
hdisk4 fscsi3 3 50060e8005271750,31000000000000
Available Enabled
2.
Execute a command that displays the information for the path whose path
priority number you want to set:
# lspath -l hdisk4 -p fscsi0 -w
50060e8005271720,31000000000000 -E
scsi_id 0x651400 SCSI ID False
node_name 0x50060e8005271720 FC Node Name False
state Enabled N/A True
priority 1 N/A True
3.
Execute a command that changes the path priority number:
# chpath -l hdisk4 -p fscsi0 -w
50060e8005271720,31000000000000 -a priority=5
path Changed
4.
Execute a command that displays the information for the path for which a
new path priority number has been set:
# lspath -l hdisk4 -p fscsi0 -w
50060e8005271720,31000000000000 -E
scsi_id 0x651400 SCSI ID False
