Setting partition-availability priorities for your managed system

To avoid shutting down mission-critical workloads when your server firmware deconfigures a failing processor, you can use the Hardware Management Console (HMC) to set partition-availablity priorities for the logical partitions on your managed system. A logical partition with a failing processor can acquire a replacement processor from logical partitions with a lower partition-availability priority. The acquisition of a replacement processor allows the logical partition with the higher partition-availability priority to continue running after a processor failure.

1. In the navigation pane, open Systems Management and click Servers.
2. In the work pane, select the managed system whose partition-availability priorities you want to set, click the Tasks button, and select Configuration > Partition Availability Priority.

   The HMC Classic interface is not supported in Hardware Management Console (HMC) Version 8.7.0, or later. The functions that were previously available in the HMC Classic interface are now available in the HMC Enhanced+ interface.

   When the HMC is at version 8.7.0, or later, complete the following steps to set partition-availability priorities:

   1. In the navigation pane, click the Resources icon .
   2. Click All Systems. The All Systems page is displayed.
   3. In the work pane, select the system and click System Actions > Legacy > Partition Availability Priority.
3. Select the logical partitions whose partition-availability priority you want to set, set Availability priority to the partition-availability priority value that you want to use for all selected logical partitions, and click OK. You can enter any value from 0 to 255 into Availability priority, or you can select one of the preset choices. All selected logical partitions are set to the same partition-availability priority value.
4. Repeat this procedure for other logical partitions to set the partition-availability priority for those logical partitions.
