about the LUs that are to be deleted but still contains information about
other LUs.
3. Execute the HDLM configuration management utility (dlmcfgmgr) to
delete the path that was disconnected from the host from the HDLM
driver.
# /opt/DynamicLinkManager/bin/dlmcfgmgr -a
The HDLM device is deleted. After it is deleted, the host is not restarted.
4. Execute the view -path operation of the HDLM command to review path
statuses after the configuration change.
The following is an example of the command:
# /opt/DynamicLinkManager/bin/dlnkmgr view -path
Paths:000006 OnlinePaths:000006
PathStatus IO-Count IO-Errors
Online 27 0

Deleted paths are not output. In the example (above) of path statuses
after a configuration change, the path IDs 000002 and 000006 are
deleted.
As shown above, if a path is removed by dynamic reconfiguration, the
remaining path IDs are not consecutive. Then, if you perform a reboot,
reconfiguration of the path IDs might cause the path IDs after the reboot
to be different from the path IDs before the reboot.
Specifying Whether a Logical Unit Is To Be Managed by HDLM (When
Not Using Solaris Cluster)
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
The dlmsetconf Utility for Creating the
HDLM Driver Configuration Definition File on page 7-23.
