•Patches to the auto_parms utility are needed to process the SYSINFO.TXT file during the boot of the disk. Please refer to the Download DRD and Patches webpage at https:// h20392.www2.hp.com/portal/swdepot/ displayInstallInfo.do?productNumber=DynRootDisk#download for information about the appropriate patches to install.

•A system administrator can execute the drd rehost command after cloning a system image to setup the clone to run on another system.

•The initial implementation of drd rehost only supports rehosting of an LVM-managed root volume group on an Integrity virtual machine to another Integrity virtual machine, or an LVM-managed root volume group on a Blade with Virtual Connect I/O to another such Blade.

•The format of the sysinfo file is defined in sysinfo(4), which is provided by a patch documented at the Download DRD and Patches webpage at https://h20392.www2.hp.com/portal/ swdepot/displayInstallInfo.do?productNumber=DynRootDisk#download. Only files conforming to sysinfo(4) can be used for rehosting.

•The disk to be rehosted must be a bootable disk and may be specified as the argument of the -toption. If no -toption is specified, the disk to be rehosted is the inactive system image. The inactive system image is either a clone created by the drd clone command, or the original booted image that was cloned, whichever is not currently booted.

•If no -toption is specified, the inactive image chosen is checked to ensure that it is managed by LVM. However, if a disk is specified using the -toption, the volume management of the disk is not checked.

•If a preview operation is run—by specifying the -poption—the syntax of the system information file is checked, but the file is not copied to the target.

The drd rehost command syntax is:

drd rehost [-?] [-p] -f system_information_file [-q] -t

device_special_file [-v][-xextended option=value] [-x-?][-Xoption_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 -poption, a DRD command performs analysis without running the command and reports any errors.

-fsystem_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 -toption. 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, -qqwill reduce the verbosity from the default value of 4 to 2. If both -x verbosity=5 and -qqqare included on the command line, the effective verbosity is 2. The minimum verbosity level is 0. (See also the -x verbosity option.)

-tdevice_special_file

Specifies the block device special file of a single writeable physical disk. The file specified by the -foption 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, -vwill increase the effective verbosity from the default value of 4 to 5. If both -x verbosity=1 and -vvare included on the command line, the effective verbosity is 3. The maximum verbosity level is 5. (See also the -x verbosity option.)
