-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.
The drd sync command
The drd-sync(1M) command propagates file system changes—whose modification time is newer
than the clone creation time—from the booted original system to the inactive clone image.
NOTE: The initial implementation of drd sync only supports refresh of the inactive clone from
the booted original system.
A file in the root LVM volume group or VxVM disk group on the booted original system is copied
to the inactive clone if all of the following criteria is satisfied:
• The file does NOT reside in the following non-synchronized locations:
/stand/*◦
◦ /tmp/*
