.
Make sure that the boot disk is configured with the specified number of
paths.
The following shows an example of executing the command:
# bootlist -m normal -o
hdisk0 blv=hd5
hdisk0 blv=hd5
hdisk1 blv=hd5
...
Deleting a Path (of a Volume Group Other than rootvg)
The following shows an example of deleting a path of a volume group other
than rootvg.

.
Execute the following HDLM command to check the OS management path
ID of the path that is to be deleted and to determine the devices (hdisk
name) connected to the path.
# /usr/DynamicLinkManager/bin/dlnkmgr view -drv
PathID HDevName OSPathID LDEV
000000 hdisk5 00000 USP.0014050.0065
000001 hdisk5 00001 USP.0014050.0065
000002 hdisk5 00002 USP.0014050.0065
000003 hdisk10 00000 9500V.5457.0102
000004 hdisk10 00001 9500V.5457.0102
000005 hdisk10 00002 9500V.5457.0102
For each path ID (PathID column), check the entries in the HDevName and
OSPathID columns. In the following steps, device-name and OS-
management- path-ID refer to the HDevName and OSPathID items,
respectively, that you checked in this step.

.
Execute the following command to check the parent device and
connection of the path to be deleted:
Specify the device-name checked in step 1 in executing the following
command:
# lspath -Hl device-name -F "name path_id parent connection"
When hdisk10 is specified, the command and the execution results would
be as follows:
# lspath -Hl hdisk10 -F "name path_id parent connection"
name path_id parent connection
hdisk10 0 fscsi4 50060e800436e240,6a000000000000
hdisk10 1 fscsi4 50060e800436e250,6a000000000000
hdisk10 2 fscsi5 50060e800436e240,6a000000000000
Search for lines in which the path_id item matches OS-management-
path-ID. If matching lines are found, check the parent and connection
entries. In the following steps, the checked parent and connection items
correspond to fscsi-number and connection-position, respectively.

Delete the path.
