Recovery with VxVM Boot Disks (Itanium)
This section describes some basic recovery steps using the VxVM Maintenance Mode Boot
(MMB) in HP-UX 11i Version 1.5 (B.11.20). It is based on the Whitepaper located on

ndCacheTok=com.vignette.cachetoken (you can also search google for ‘vxvm_mmb
site:hp.com’ and it should pull the document as well). VxVM MMB is intended for use on
systems where the boot disk is a VxVM disk and a bootup has failed due to problems in starting
the VxVM configuration daemon. A VxVM boot disk is a disk that is made up of VxVM
volumes that contain the root, stand and possibly other file systems. On such a system, you must
resolve the VxVM problem before being able to perform a standard boot once again.
