Slot number
This number indicates the position of the slot where an HBA is mounted.
You can find the order of the slot numbers by comparing their physical
location code.
The following describes how to obtain the physical location code.

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
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
Execute a command that changes the path priority number:
# chpath -l hdisk4 -p fscsi0 -w
50060e8005271720,31000000000000 -a priority=5
path Changed
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
node_name 0x50060e8005271720 FC Node Name False
state Enabled N/A True
priority 5 N/A True
Execute the following command to find hdisk, based on
AutoPATH_ID.
# /usr/DynamicLinkManager/bin/dlnkmgr view -drv
PathID HDevName OSPathID LDEV
000000 hdisk0 00000 9500V.0051.0005
000001 hdisk1 00000 9500V.0051.0015
