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.
-p Sets preview mode. When run with the -p option, a DRD command performs analysis without
running the command and reports any errors.
-f system_information_file
Specifies the file containing the system information (hostname, IP address, network information,
etc.) to be copied to EFI/HPUX/SYSINFO.TXT on the disk specified by the -t option. See
sysinfo(4) for the syntax of this file. If not specified, the file defaults to /etc/opt/drd/
default_sysinfo_file.
-q Decreases the verbosity level by one each time it is specified. For example, -qq will reduce
the verbosity from the default value of 4 to 2. If both -x verbosity=5 and -qqq are
included on the command line, the effective verbosity is 2. The minimum verbosity level is 0.
(See also the -x verbosity option.)
-t device_special_file
Specifies the block device special file of a single writeable physical disk. The file specified
by the -f option will be written to EFI/HPUX/SYSINFO.TXT in the EFI partition of this disk.
If no target is specified, the inactive system image is used as a target.
-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.
