dlmcfgmgr Utility for Managing the HDLM Configuration

For management by HDLM, the HDLM-configuration definition utility obtains

the SCSI device information stored by Linux by detecting the information on

the path between the host and storage system to register in HDLM, and then

creates, updates, or deletes the HDLM devices. Also, this utility sets an HDLM

device as a management target or excludes it from being managed.

When an existing device is updated during execution of this utility, the

definition of the HDLM device is inherited.

Whenever you make any changes to the storage system configuration

(adding or deleting an LU or path), LU partitions, or hardware configuration

on the host, restart the host or execute the dlmcfgmgr utility to re-configure

the HDLM devices.

The operation log is obtained while the dlmcfgmgr utility is executed.
