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
