Managed System Compartment Software

Table 2-8 lists the supported versions of the products that provide the compartments that gWLM manages. A system managed by gWLM must have at least one of these products installed.

Table 2-8 Managed System Compartment Software

Software Requirements

nPartitions

Instant Capacity version 8.02 or later (but not including version 9.0 or later) is required to simulate CPU movement between GiCAP group members.

Virtual Partitions

vPars version A.03.01.05 or later is supported. However, vPars version A.03.04 or later is strongly recommended due to potential stability issues. With vPars versions earlier than version A.03.04, a race condition can occur when gWLM migrates CPU resources rapidly. In rare cases, this can cause the virtual partition to crash. It can also produce a panic. For more information about this problem, see the HP Virtual Server Environment Management for Integrity Version 4.0 Release Notes (section entitled “Rare Incompatibility with Virtual Partitions”).

The following tunable kernel parameters must be configured as specified:

max_thread_proc: at least 256
nkthread: max_thread_proc + the number of threads needed by all the other processes on the system

Virtual machines

HP Integrity Virtual Machines version A.02.00 or later. For HP-UX 11i v2, install patches PHKL_33052, PHKL_33604, and PHKL_33605.




	NOTE: These patches might have additional patch dependencies and might be superseded by more recent patches.

The following tunable kernel parameters must be configured as shown:

max_thread_proc: at least 256
nkthread: max_thread_proc + the number of threads needed by all the other processes on the system

Processor sets (psets)

For HP-UX 11i v1, you must download and install the following free products from http://software.hp.com:

HP-UX Processor Sets
The HP-UX 11i Version 1 Quality Pack

This software is already included in HP-UX 11i v2 and HP-UX 11i v3.

Fair-Share Scheduler (FSS)

The PRM-Sw-Krn.PRM-KRN fileset must be installed. The following command displays the fileset information if it is installed on the system. Any version of the fileset is acceptable.

# /usr/sbin/swlist PRM-Sw-Krn.PRM-KRN

If this fileset is not installed, it is available for installation as part of the bundle PRMKernelSW, which is available from Software Depot (http://software.hp.com).

The following patches are required:

HP-UX 11i v1: PHKL_30034, PHKL_30035, PHKL_31993, PHKL_31995, PHKL_32061.
HP-UX 11i v2: PHKL_33052, PHKL_33604, PHKL_33605.




	CAUTION: A system panic will result if you attempt to deploy an SRD based on FSS groups on a system without these patches.




	NOTE: These patches might have additional patch dependencies and might be superseded by more recent patches.

The following tunable kernel parameters must be configured as shown:

max_thread_proc: at least 256
nkthread: max_thread_proc + the number of threads needed by all the other processes on the system
