Dynamic Root Disk A.3.13* Administrator's Guide HP-UX 11i v2, HP-UX 11i v3 (766142-001, March 2014)

-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.
The drd runcmd command
The drd-runcmd(1M) command runs a DRD-safe command, which is specified by command <args>,
on the cloned (inactive) system image.
The drd runcmd command runs the designated command on the inactive system image. Several
commands, known as DRD-safe commands, can be executed with drd runcmd . See Maintaining
Software on the Cloned Image for more information about the DRD-safe commands.
The drd runcmd command mounts the inactive system image if it has not been mounted. Generally,
when drd runcmd completes, it unmounts the inactive system image. However, if the inactive
system image was mounted before the command, drd runcmd leaves it mounted after completion
of drd runcmd.
