from being managed immediately after execution of the utility, except
when the specified HDLM device is in use. If the specified HDLM device is
in use, an error occurs.
You can use this parameter to exclude the HDLM devices that are no
longer required to be managed by HDLM. The excluded HDLM devices are
not displayed with the dlnkmgr command's view operation and the HDLM
device files for these devices are not created. Therefore, these devices
become unavailable to the user.
-i {logical-device-file-name-of-the-HDLM-device ...|all}
Use this parameter to reset the HDLM device that has been excluded from
being managed to an HDLM management target.
You can specify one or more logical device file names of an HDLM device
(/dev/sddlm[aa-pap]) as a parameter value. For details on logical device
files for HDLM devices, see
2-11.
If all the HDLM devices are the target, specify all. Specifying all
together with a logical device file name of an HDLM device causes an
error.
Specifying the -i parameter without a parameter value causes an error.
If you specify a logical device file name of an HDLM device that does not
exist, non-HDLM device, or HDLM device that is already defined as a
management target, the specification is ignored.
The dlmcfgmgr utility with this parameter can be executed a number of
times while Linux is running. The specified HDLM device becomes
available immediately after execution of the utility.
You can use this parameter to reset an HDLM device that must be
managed again to a management target. The HDLM devices reset to a
management target are displayed with the dlnkmgr command's view
operation, and the HDLM device files for the devices are created.
Therefore, these devices become available to the user again.
-v [-udev]
Use this parameter to display the management status and configuration
information of all the HDLM devices recognized by HDLM.
Specify this parameter when you want to get the current status of
management, configuration, or other information for the HDLM device.
With this parameter, the message confirming that the utility is executed is
not displayed at execution of the utility even if you omit the -s
parameter. Unlike the -o, -i, or -u parameter, the utility with this
parameter specified can operate during the I/O processing to and from
the HDLM device.
If you also want to check the udev name assigned to the SCSI device that
corresponds to the HDLM device, specify the -udev parameter.
-u {logical-device-file-name-of-the-HDLM-device ...|all}
Use this parameter to delete the paths displayed as hyphens (-) in the
Device column of HDLM device configuration information that is displayed
by specifying the -v parameter.
