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 DRD Web site, located at http://docs.hp.com/en/DRD.
