Deleting A Path (Of A Volume Group Other Than Rootvg) - Hitachi XP P9500 User Manual

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.
1 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
000000 hdisk5
000001 hdisk5
000002 hdisk5
000003 hdisk10
000004 hdisk10
000005 hdisk10
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.
2 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
hdisk10
hdisk10
hdisk10
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.
3 Delete the path.
.
# rmpath -l device-name -p fscsi-number -w connection-position
The following example deletes the path whose OS-management-path-ID
is 2:
# rmpath -l hdisk10 -p fscsi5 -w 50060e800436e240,6a000000000000
4 Check that the path has been deleted.
.
# /usr/DynamicLinkManager/bin/dlnkmgr view -drv
