.
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
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.
a
.
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
000002 hdisk2 00000 9500V.0051.0020
000003 hdisk0 00001 9500V.0051.0005
000004 hdisk1 00001 9500V.0051.0015
000005 hdisk2 00001 9500V.0051.0020
b
.
Execute the following command to find the parent device of hdisk
(the HBA device instance).
# lsdev -C -l hdisk4 -F 'parent'
fscsi0
c
.
Execute the following command to find the physical location code,
based on the HBA device instance.
# lscfg -vp -l fscsi0
The obtained physical location code is in the Uaa.bb-Pcc-Idd format.
The first letters, Uaa.bb, depend on the model of the host. HDLM
selects the path with the lowest value for aabbccdd. When the
physical location code is in another format, the priority of paths is not
decided. Note that the top priority path does not change because of,
for example, restarting a computer in the same environment.
