HP Dynamic Root Disk (DRD) drd umount -? -p -q -v -x extended option=value -x -? -X optionfile

The drd umount command fails:

•If the inactive system image was created by a drd clone command and no file system is mounted at /var/opt/drd/mnts/sysimage_001.

•If the inactive system image was the original source system when a drd clone command was run and no file system is mounted at /var/opt/drd/mnts/sysimage_000.

If a cloned file system is mounted, drd umount unmounts the file systems, unmounting the root file system (/) last. For a system with an LVM root, drd umount uses deactivate and vgexport to export the inactive volume group from the system. This makes the unmounted inactive system image invisible to LVM management commands. For a system with a VxVM root, the inactivate image must remain imported to ensure that it is bootable.

The drd umount command syntax is:

drd umount [-?] [-p] [-q] [-v] [-x extended option=value] [-x -?] [-X option_file]

Options

-?

Displays the usage message for a DRD command. This option cannot be used with other options.

-p

Sets preview mode. When run with the -poption, a DRD command performs analysis without running the command and reports any errors.

-q

Decreases the verbosity level by one each time it is specified. For example, -qqwill reduce the verbosity from the default value of 4 to 2. If both -x verbosity=5 and -qqqare included on the command line, the effective verbosity is 2. The minimum verbosity level is 0. (See also the -x verbosity option.)

-v

Increases the verbosity level by one each time it is specified. For example, -vwill increase the effective verbosity from the default value of 4 to 5. If both -x verbosity=1 and -vvare included on the command line, the effective verbosity is 3. The maximum verbosity level is 5. (See also the -x verbosity option.)

-xextended_option=value

Sets the extended option to a value.

-x -?

Displays the list of possible -x(extended) options.

-Xoption_file

Gets the extended options from a file.

Extended options

The following extended options are available:

-x alternate_bootdisk=block_device_special_file

This is the alternate boot disk. The alternate boot disk must be specified as a block device special file.

-x HA_alternate_bootdisk=block_device_special_file

This is the High Availability alternate boot disk. The High Availability alternate boot disk must be specified as a block device special file. High Availability alternate boot disk is supported only on Itanium-based architecture and for PA-RISC systems that support hardware partitions.

-x ignore_unmounted_fs={truefalse}

(Default is false) Controls whether a clone fails when an unmounted file system in the root volume group is detected.
