Setting up cross-partition management
The following steps give an overview of how to implement cross-partition
management.
Step 1. (Optional) Set up secure WLM communications.
Follow the procedure HOW TO SECURE COMMUNICATIONS in
wlmcert(1M)—skipping the step about starting/restarting the WLM
daemons. You will do that later in this procedure.
Step 2. Create a WLM configuration file for each partition.
Each partition on the system must have the WLM daemon wlmd running.
Create a WLM configuration file for each partition, ensuring each
configuration uses the primary_host keyword to reference the partition
where the global arbiter is running. For information on the
primary_host syntax, see “Setting up your WLM configuration file” on
page 264.
NOTE If the cntl_base_previous_req tunable is set to 0 in a WLM
configuration that contains goal-based SLOs, those SLOs may not
release cores properly when the cores are no longer needed.
cntl_base_previous_req is set to 1 by default. For more information,
see “Releasing cores properly (optional)” on page 233 or see wlmconf(4).
On systems with WLM installed, you can use the example configuration:
/opt/wlm/examples/wlmconf/par_usage_goal.wlm
NOTE Do not edit this configuration file in place. Copy it to a location outside
/opt/wlm/. Then edit and activate the configuration from the new
location.
