VERITAS Volume Manager
Chapter 460
VERITAS Volume Manager
Base VERITAS Volume Manager 3.1 for HP-UX (VxVM), is a
state-of-the-art online disk management software product. It is the
default disk storage mechanism for HP-UX 11i Version 1.5 (B.11.20).
VxVM is functionally equivalent to the HP Logical Volume Manager
(LVM) and the HP MirrorDisk/UX products.
Base VERITAS Volume Manager 3.1 for HP-UX is bundled with all
HP-UX 11i Version 1.5 (B.11.20) systems and includes:
• support for managing the root disk (i.e., rootability)
VERITAS Volume Manager 3.1 for HP-UX (B9116AA) is an optional
product available at an extra charge. The add-on VxVM product includes
features such as mirroring, RAID-5, and DMP for active/active devices.
See VERITAS Volume Manager 3.1 for HP-UX Release Notes for more
information about the add-on VxVM product.
VxVM Libraries
VxVM adds two new kernel libraries, libvxvm.a and libvxdmp.a, that
get built into the base HP-UX kernel. VxVM also provides tunables
defined in /usr/conf/space.h.d/vxvm_space.h and
/usr/conf/space.h.d/vxdmp_space.h, these tunables can be found in
/usr/conf/master.d/vxvm and /usr/conf/master.d/vxdmp. Detailed
information of these tunables can be found in the VERITAS Volume
Manager 3.1 Administrator's Guide on the http://docs.hp.com web site.
VxVM adds four new init scripts:
• /sbin/rc0.d/K930vxvm-daemon-kill
• /sbin/rc1.d/S092vxvm-startup2 starts VxVM I/O daemons and
enables the VxVM configuration daemon which rebuilds the
/dev/vx/dsk and /dev/vx/rdsk directories. This script also rebuilds
the user level nodes for all the DMP devices in /dev/vx/dmp and
/dev/vx/rdmp that were detected by the kernel.
• /sbin/rc1.d/S093vxvm-reconfig VxVM reconfiguration init script
• /sbin/rc2.d/S095vxvm-recover handles recovery of stale volumes.
Also starts the VxVM watch daemon, vxrelocd (1M), which sends
email to the system administrator when any problems are found.
