HDLM device that is not managed by HDLM, that HDLM device will not be
managed by HDLM.
-o {
logical-device-file-name-of-the-HDLM-device
...|all}
Use this parameter to exclude the management-target HDLM device from being
managed.
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
2.6 Logical Device Files for HDLM Devices
.
If you want to exclude all the HDLM devices from being managed, specify
all
.
Specifying
all
together with a logical device file name of the HDLM device
causes an error.
Specifying the
-o
parameter without a parameter value also 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
non-HDLM-managed device, 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 can be excluded 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
2.6 Logical Device Files for HDLM Devices
.
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
