Unrehosting overview | HP Dynamic Root Disk (DRD) instruction

3.The rehosted disk should be chosen from the EFI menus for boot.

4.After the system is booted, the DRD registry can be removed by issuing the command:

# rm /var/opt/drd/registry/registry.xml

If the rehosted disk is the only disk to be moved to the new system, the disk can be booted by interrupting the boot sequence and booting with the command: hpux –lq /stand/vmunix. The -lqoption will disable quorum checking, allowing you to boot from the single copy.

7.4 Unrehosting overview

For details of the drd unrehost command, including available options and extended options, see The drd unrehost command.

The drd unrehost command removes EFI/HPUX/SYSINFO.TXT, and optionally preserves a copy of it in a file on the booted system.

You can execute the drd unrehost command after previously executing 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), see the Download DRD and Patches webpage, located at https:// h20392.www2.hp.com/portal/swdepot/ displayInstallInfo.do?productNumber=DynRootDisk#download.
