HP Matrix Operating Environment 7.0 Release Notes

4. Create a placeholder logical server to prevent the MAC addresses from being
assigned to new logical servers:
1. Create a new logical server template without specifying any storage entries in
the storage configuration.
2. In the network selection page, click Add Network Entries.
NOTE: LSM shows the MAC addresses that were part of the unmanaged
logical server.
3. Click Next and then Finish to create the logical server template.
This Integrity VM logical server template cannot be activated because it lacks
storage entries, but the new template prevents the MAC addresses of the
unmanaged logical server from being used again.
You may now create and activate Integrity VM logical servers.
• To correct duplicate MAC and/or WWNs:
1. Delete the newly created Integrity VM logical server (after backing up its data, if
necessary).
2. Perform one of the procedures described above under To prevent duplicate MACs and/or
WWNs.
You may now create and activate Integrity VM logical servers.
HP Logical Server Automation service may run out of memory on large scale systems
On large scale systems, with large numbers of managed nodes and/or large numbers (1000+)
of logical servers on a 64-bit CMS, the HP Logical Server Automation service may run out of
memory and display out of memory errors in the /logs/hp_lsa_service.log or /logs/
vselog.lsm.log file. You may see the following errors:
java.lang.OutOfMemoryError: GC overhead limit exceeded
java.lang.OutOfMemoryError: Java heap space
java.lang.OutOfMemoryError: PermGen space
For more information, see “Configuring HP Insight Management for large environments” in the HP
Insight Management 7.0 Installation and Configuration Guide at Matrix OE Information Library.
Suggested action 1
To correct the GC overhead limit and/or Java heap space errors, modify the configuration file to
increase memory allocation:
1. Modify the configuration file (shown in the default location) at C:\Program Files\HP\
Virtual Server Environment\conf\hp_lsa_service.conf.
2. Increase the value of wrapper.java.maxmemory=1024. HP suggests a value of 2048.
3. Restart the HP Logical Server Automation service.
Suggested action 2
To correct the PermGen space error, modify the configuration file to increase permanent generation
size:
1. Modify the configuration file (shown in the default location) at C:\Program Files\HP\
Virtual Server Environment\conf\hp_lsa_service.conf.
2. Add the following line. (Change additional.2 to additional.3 if a line with
additional.2 already exists; change additional.2 to additional.4 if lines with
additional.2 and additional.3 already exist, and so on.)
wrapper.java.additional.2=-XX:PermSize=32m -XX:MaxPermSize=128m
3. Restart the HP Logical Server Automation service.
