Specifying Whether A Logical Unit Is To Be Managed By Hdlm (When Not Using Sun Cluster) - Hitachi XP P9500 User Manual

4 Execute the dlmcfgmgr utility for managing the HDLM configuration to
.
delete the LU, which is disconnected from the host, from the HDLM driver.
# /opt/DynamicLinkManager/bin/dlmcfgmgr -a
The HDLM device will be deleted without restarting the host.
5 Execute the dlnkmgr command's view -path operation to check the path
.
status after the configuration change.
The following shows an example of executing the command:
# /opt/DynamicLinkManager/bin/dlnkmgr view -path

The deleted LU is no longer output. In the example of the configuration
after the change, the path IDs 000002 and 000006 are deleted.
When an LU is deleted via dynamic reconfiguration, path IDs become
inconsecutive, as shown in this example. If you reboot the host, path IDs
might change because they are reconfigured during the reboot.

This section describes the procedures for modifying the configuration of an
HDLM-managed device.
You must use the dlmsetconf utility for creating the HDLM driver
configuration definition file to modify the configuration of an HDLM-managed
device, therefore you should also see
