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 .
