Dynamic Root Disk A.3.13* Administrator's Guide HP-UX 11i v2, HP-UX 11i v3 (766142-001, March 2014)
-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 unrehost command
The drd-unrehost(1M) command removes EFI/HPUX/SYSINFO.TXT, and optionally preserves a
copy of it in a file on the booted system.
A system administrator can execute the drd unrehost command after having previously issued
the drd rehost command, specifying the same target, if the disk should not be rehosted.
The format of the sysinfo file is defined in sysinfo(4). To determine the most recent patch that supplies
sysinfo(4), please refer to the Download DRD and Patches webpage at https://

productNumber=DynRootDisk#download.
The drd unrehost command syntax is:
drd unrehost[-?] [-p] -f system_information_file [-q] -t
device_special_file [-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.
