-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:

0Only ERRORS and the starting/ending BANNER messages.

1Adds WARNING messages.

2Adds NOTE messages.

3Adds INFO messages (informational messages preceded by the * character.)

4(Default) Adds verbose INFO messages.

5Adds 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={truefalse}

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={truefalse}

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 -pon the command line. The default is false. This option is available on every DRD command except drd runcmd.

-x reboot={truefalse}

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:

0Only ERRORS and the starting/ending BANNER messages.

1Adds WARNING messages.

2Adds NOTE messages.

3(Default) Adds INFO messages (informational messages preceded by the * character.)

4Adds verbose INFO messages.

5Adds additional detailed INFO messages.
