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.
