HP Insight Global Workload Manager 6.3 User Guide

Workaround
Time a gwlm list command on the CMS. If it takes more than 10 seconds, perform the following
steps:
1. In the file /etc/opt/gwlm/conf/gwlmcms.properties (HP-UX) or
install-path\VirtualServerEnvironment\conf\gwlmcms.properties
(Windows), increase the CMS database cache size by increasing the value of the
com.hp.gwlm.cms.cachesize property by 25%. (The cache is more memory efficient if
the size is near a power of 2. If your target cache size is close to a power of 2, round it up
to the next power. For example, if your target cache size is 60,000, round it up to 66,000.)
2. Stop and restart gwlmcmsd using the following commands.
NOTE: Stopping gwlmcmsd disables Virtualization Manager and Capacity Advisor.
# gwlmcmsd --stop
# gwlmcmsd
Combining psets and virtual partitions
When using psets on virtual partitions, assigning CPUs to virtual partitions by either path or cell
specification can result in processes losing their processor set affiliations when CPUs are removed.
Workaround
Two workarounds are available:
• Do not assign CPUs to virtual partitions by either path or cell specification.
• Set the gWLM policy minimum for pset 0 (the default/OTHER workload) to be greater than
or equal to the sum of path-specific CPUs and cell-specific CPUs.
Error during discovery of compartments
The following message might be displayed when you use the Manage New Systems wizard or
the gwlm discover command:
Error during discovery of compartments.
In addition, the /var/opt/gwlm/gwlmagent.log.0 file contains the following message:
com.hp.gwlm.common.PlatformException: /usr/sbin/parstatus -w exited
with a non-zero exit status. Captured stderr is: Error: Unable to get
the local partition number.
Workaround
This is most likely due to having an outdated version of the nPartition Provider software. Global
Workload Manager uses a command that is made available by the nPartition Provider, which is
typically in every version of HP-UX, to determine system capabilities.
You can also use the /opt/vse/bin/vseassist command to diagnose the issue.
Install the latest nPartition software, even if you are not using nPartitions.
For HP-UX 11i v1, use version B.11.11.01.03.01.01 or later.
For HP-UX 11i v2 on HP 9000 servers, use version B.11.23.01.03.01.01 or later.
For HP-UX 11i v2 on HP Integrity servers, use version B.11.23.01.04 or later.
You can find the nPartition Provider at the following locations:
• The quarterly AR CD starting May 2005
• The Software Depot website: http://software.hp.com
