Managing persistent memory volume

You can view and manage the persistent memory volume that is assigned to a logical partition by using the Hardware Management Console (HMC).

Before you begin

When you are using HMC version 9.1.940, or later, and when the firmware is at level FW940, or later, you can view and manage the persistent memory volume that is assigned to a logical partition by using the Hardware Management Console (HMC). You can manage the persistent memory volume only when the logical partition is in the Not activated state. You cannot add virtual Persistent Memory (PMEM) volumes to a logical partition in which the Simplified Remote Restart (SRR) capability is enabled.

Note:
If a live partition mobility (LPM) operation fails due to insufficient memory in the destination system, complete the following steps to resolve the issue:
  1. Check if any of the logical partitions are in the Not Activated state.
  2. Check whether you require vPMEMs of the logical partition in the destination system.
  3. If the vPMEMs are not required in the destination system, delete all vPMEMs of the logical partition and resume the LPM operation.
