HP Dynamic Root Disk (DRD) A.1.10 The drd unrehost command, x mirrordisk=blockdevicespecialfile

-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.

A.1.10 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:// h20392.www2.hp.com/portal/swdepot/ displayInstallInfo.do?productNumber=DynRootDisk#download.
