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.
You can specify one or more logical device file names of an HDLM device (
/
dev/sddlm[
aa-pap
]
) as a value of the
-u
parameter. For details on logical
device files for HDLM devices, see 2.6 Logical Device Files for HDLM Devices.
Specifying the
-u
parameter without the parameter value cases an error.
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. If you specify the
logical device file name for an HDLM device that does not exist or a non-HDLM
device, the specification is ignored.
The
dlmcfgmgr
utility with this parameter can be executed a number of times
while Linux is running. The re-configured HDLM device becomes available
immediately after execution of the utility.
You can use this parameter to delete information about HDLM device paths for
which a compatible SCSI device does not exist (paths displayed as hyphens (
-
) in
the
Device
column of the HDLM device configuration information that is
displayed by specifying the
-v
parameter), and to release the registration of the
path from HDLM.
In general, the path information for the HDLM device is added at HDLM startup
