Veritas Volume Manager 5.0.1 Administrator's Guide, HP-UX 11i v3, First Edition, November 2009

LIF LABEL record is initialized with volume extent information for the stand,
root, swap, and dump (if present) volumes.
See “Setting up a VxVM root disk and mirror” on page 115.
From the AR0902 release of HP-UX 11i onward, you can choose to configure either
a VxVM root disk or an LVM root disk at install time.
See the HP-UX Installation and Configuration Guide.
See the Veritas Volume Manager Troubleshooting Guide.
VxVM root disk volume restrictions
Volumes on a bootable VxVM root disk have the following configuration
restrictions:
■ All volumes on the root disk must be in the disk group that you choose to be
the bootdg disk group.
■ The names of the volumes with entries in the LIF LABEL record must be
standvol, rootvol, swapvol, and dumpvol (if present). The names of the
volumes for other file systems on the root disk are generated by appending
vol to the name of their mount point under /.
■ Any volume with an entry in the LIF LABEL record must be contiguous. It can
have only one subdisk, and it cannot span to another disk.
■ The rootvol and swapvol volumes must have the special volume usage types
root and swap respectively.
■ Only the disk access types auto with format hpdisk, and simple are suitable
for use as VxVM root disks, root disk mirrors, or as hot-relocation spares for
such disks. An auto-configured cdsdisk format disk, which supports the
Cross-platform Data Sharing (CDS) feature, cannot be used. The vxcp_lvmroot
and vxrootmir commands automatically configure a suitable disk type on the
physical disks that you specify are to be used as VxVM root disks and mirrors.
■ The volumes on the root disk cannot use dirty region logging (DRL).
■ In this release, iSCSI devices cannot be used for VxVM rootable disks. HP-UX
11i version 3 does not support iSCSI devices as system root disks, because
iSCSI depends on the network stack which is initialized after the boot.
In addition, the size of the private region for disks in a VxVM boot disk group is
limited to 1MB, rather than the usual default value of 32MB. This restriction is
necessary to allow the boot loader to find the /stand file system during
Maintenance Mode Boot.
