Dynamic Root Disk A.3.13* Administrator's Guide HP-UX 11i v2, HP-UX 11i v3 (766142-001, March 2014)

-v Increases the verbosity level by one each time it is specified.
For example, -v will increase the effective verbosity from
the default value of 4 to 5. If both -x verbosity=1 and
-vv are included on the command line, the effective
verbosity is 3. The maximum verbosity level is 5. (See also
the -x verbosity option.)
-x extended_option=value Sets the extended option to a value.
-x -? Displays the list of possible -x (extended) options.
-X option_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={true|false}
(Default is false) Controls whether a clone fails when an
unmounted file system in the root volume group is detected.
-x
logfile=/var/opt/drd/drd.log
This is the path to the log file for this command. Each time
DRD is run, this file will grow larger. This can be changed,
for example, to a month-specific location for easier
archiving, off-host backup, and rotation.
-x log_verbosity=4 (Default.) Specifies the level of log verboseness. Replace 4
with the following values:
0 Only ERRORS and the starting/ending BANNER
messages.
1 Adds WARNING messages.
2 Adds NOTE messages.
3 Adds INFO messages (informational messages preceded
by the * character.)
4 (Default) Adds verbose INFO messages.
5 Adds additional detailed INFO messages.
-x
mirror_disk=block_device_special_file
Specifies the target's block device special file of the mirror
disk. The block device special file should refer to an entire
disk, not to a partition. This option requires that LVM
mirroring is installed. The block device special file specified
is used to mirror each logical volume in the target of the
clone operation.
-x overwrite={true|false} Specifies whether drd clone should overwrite existing
information on the target disk. That is, it controls whether a
disk containing boot, LVM, or VxVM records can be
overwritten. The -x overwrite=false (default) prevents
a disk that contains boot, LVM, or VxVM records from being
overwritten. The -x overwrite=true allows a disk to
be overwritten, even if it contains boot, LVM, or VxVM
records. Note that DRD does not overwrite a disk associated
with an active LVM volume group or VxVM disk group,
regardless of the setting of the overwrite option. If a
previously created clone is mounted, use the drd umount
command to unmount it before attempting to create a new
clone on the disk.
