4. HDLM Operation
376
The following is an example of executing the
dlmcfgmgr
utility:
# /sbin/dlmcfgmgr -u
logical_device_file_name_of_HDLM_device
9. Check
/var/opt/DynamicLinkManager/log/dlmcfgmgr1.log
or execute
the
dlmcfgmgr
utility (
dlmcfgmgr -v
) to make sure that the HDLM device that
corresponds to the deleted LU was deleted.
The following is an example of executing the
dlmcfgmgr
utility:
# /sbin/dlmcfgmgr -v
(5) Deleting a Path to an Existing LU
To delete a path to an existing LU (HDLM device):
1.
Stop all accesses to the relevant LU.
2. Use the management program of the storage system to delete a path to the relevant
LU.
For more information on deleting a path, see the manual provided with the storage
system.
3. When you want to delete a path to the LU without restarting the host, go to step
4. When you want to delete a path while restarting the host, go to step 5.
4. Delete the SCSI device for the path that was deleted in step 2.
Since the host has not been restarted, the SCSI device for the path that was deleted
in step 2 was not deleted. Execute the command for deleting the device shown in
Table 4-3: Adding or Deleting a SCSI Device to manually delete the SCSI
device.
5. Restart the host on which the HDLM is installed.
If you performed step 4, the host does not have to be restarted. Go to step 6.
6. Execute the HDLM-configuration definition utility (
dlmcfgmgr -v
) or the
view
operation of the
dlnkmgr
command (
dlnkmgr view -drv
) (optional).
Check if the SCSI device name of the HDLM device whose path was deleted in
the above step 2 is represented with a hyphen (-).
The following are examples of executing the command or utility:
When executing the
dlmcfgmgr
utility with the
-v
option:
# /sbin/dlmcfgmgr -v
When executing the
view
operation with the
-drv
option:
# /opt/DynamicLinkManager/bin/dlnkmgr view -drv
