Partitions
WLM manages virtual partitions and nPartitions through a global arbiter. WLM’s global
arbitration uses non-secured communications. A rogue user could manipulate the
communications, resulting in one or more partitions being granted an incorrect number of
cores. Use global arbitration only on trusted local area networks.
By default, wlmpard communicates to the partitions on a system through port 9691.
If the partitions use a firewall or if you are using the HP-UX Bastille product on the
partitions, it is likely that communications on this port are being blocked. To use wlmpard in
your environment, specifically allow port 9691 or another port to be open to incoming
connections. If you use a port other than 9691, be sure to restart wlmpard to communicate on
the new port.
If you use Bastille or the Install-Time-Security Levels to configure the IPFilter firewall, you
may want to put the rules regarding which port to leave open in the following file:
/etc/opt/sec_mgmt/bastille/ipf.customrules
After that, run bastille -b to load the rules and make sure that Bastille does not remove
them later during subsequent runs/lockdowns.
