-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.
-x preview={true|false}
If true, run this command in preview mode only. That is, complete the analysis phase and exit;
no changes are committed to disk. This option has the same effect as specifying -p on the
command line. The default is false. This option is available on every DRD command except
drd runcmd.
-x reboot={true|false}
If true, specifies the system is rebooted at the successful completion of a drd activate
operation. The default is false.
-x verbosity=3 (Default.)
Specifies the level of stdout/stderr verboseness. Replace 3 with the following values:
0 Only ERRORS and the starting/ending BANNER messages.
1 Adds WARNING messages.
2 Adds NOTE messages.
3 (Default) Adds INFO messages (informational messages preceded by the * character.)
4 Adds verbose INFO messages.
5 Adds additional detailed INFO messages.
