4 Setting up PRM
This chapter explains how to set up PRM. It covers the following topics:
• Installing PRM
• Setting up your disks
• Setting PRM to start automatically at reboot
Installing PRM
PRM is installed using the Software Distribution (SD) utilities.
Installation of PRM typically requires a kernel build and a reboot of the
system. For more specific information, see the release notes, which are
available in the /opt/prm/newconfig/RelNotes/ directory. See the release
notes on http://docs.hp.com for the most up-to-date information.
During installation, a minimal /etc/prmconf file is created. After
installation, PRM is unconfigured and disabled; the standard HP-UX
resource management still controls the system.
PRM is installed at /opt/prm/.
Setting up your disks
To use PRM’s disk bandwidth management, the disks to be controlled by
PRM must be mounted and under the control of HP’s Logical Volume
Manager (LVM) or VERITAS Volume Manager (VxVM).
If you would like to use disk bandwidth management with LVM, install
patch PHKL_28150.
If you would like to use disk bandwidth management with VxVM, you
will need to install a patch if you are using HP-UX 11i v1 (B.11.11). (For
information on this patch, visit http://www.hp.com/go/prm.) On HP-UX
11i v2 (B.11.23) and later, no patches are needed.
