allocations (that is, to delete the paths) to the relevant LU from ports of the storage
system.
For details on canceling path allocations (deleting paths), see the manual provided
with the storage system.
3.
If you want to delete an HDLM device that corresponds to the LU without
restarting the host, perform steps 4 and 5. If you want to delete the LU and restart
the host, go to step 6.
4.
Delete the SCSI device for the path whose allocation was cancelled in step 2.
Since the host has not been restarted, the SCSI device for the path whose
allocation was cancelled in step 2 was not deleted. To delete the SCSI device, you
need to manually execute the command for deleting the device shown in
Table 4-3: Adding or Deleting a SCSI Device
.
5.
Execute the HDLM-configuration definition utility (
dlmcfgmgr -r
).
Apply, to the HDLM device, the information about the SCSI device that was
deleted in step 4.
The following is an example of executing the
dlmcfgmgr
utility:
# /sbin/dlmcfgmgr -r
6.
Restart the host on which HDLM is installed.
If you performed steps 4 and 5, you do not need to restart the host. Go to step 7.
7.
Execute the
dlmcfgmgr
utility (
dlmcfgmgr -v
) or the
view
operation
(
dlnkmgr view -drv
).
Make sure that all the SCSI device names corresponding to the LU for which path
allocations were cancelled in step 2 are represented with a hyphen (-) (optional).
The following is an example of executing the
dlmcfgmgr
utility with the
-v
option:
# /sbin/dlmcfgmgr -v
The following is an example of executing the
view
operation with the
-drv
option:
# /opt/DynamicLinkManager/bin/dlnkmgr view -drv
8.
Execute the
dlmcfgmgr
utility (
dlmcfgmgr -u
logical_device_file_name_of_HDLM_device
) on all the HDLM devices
corresponding to the LU for which path allocations were cancelled in step 2 to
unregister the HDLM devices.
Path information on the relevant HDLM device is deleted.
