7.3 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.
