Setting up PRM
Setting PRM to start automatically at reboot
Chapter 486
LVM divides the disk in much the same way as the hard partitions
implemented under earlier versions of HP-UX. However, logical volumes
are much easier to reconfigure than partitions, and they can span two or
more disks. These two attributes make LVM a much more powerful and
flexible tool than hard partitions.
LVM is the most common disk-management method for current versions
of HP-UX on all platforms.
LVM uses the concept of a volume group, which is a collection of one or
more disks. A volume group can be divided into several partitions, which
are called logical volumes.
NOTE When setting up LVM, do not create swap partitions in any volume group
that is under PRM control.
For information on using LVM, see HP-UX System Administrator’s Guide
(HP-UX 11i v3) or Managing Systems and Workgroups (HP-UX 11i v1 or
HP-UX 11i v2). This book is available on the web at http://docs.hp.com.
Setting PRM to start automatically at reboot
After rebooting your system, PRM is unconfigured and disabled if you
have not previously configured the PRM startup script.
To preserve your configuration across reboots, modify the variables in the
PRM startup script /etc/rc.config.d/prm to automatically configure PRM
on reboot. This startup script configures PRM using the file you specify
in /etc/rc.config.d/prm. If you do not specify a file, PRM uses an internal
copy of the previous configuration file (either /var/tmp/PRM.prmconf or
/var/tmp/PRM.prmconf.old if PRM.prmconf is not present).
For information, see the file /etc/rc.config.d/prm or “Protecting the PRM
configuration from reboots” on page 194.
