Adding a paging VIOS partition to the shared memory pool using the HMC

You can use the Hardware Management Console (HMC) to assign a second Virtual I/O Server (VIOS) logical partition (hereafter referred to as a paging VIOS partition) to the shared memory pool.

Before you assign a paging VIOS partition to the shared memory pool, complete the following steps:

Verify that only one paging VIOS partition is currently assigned to the shared memory pool.
Verify that the paging VIOS partition that is currently assigned to the shared memory pool is running.
Verify that the Virtual I/O Server logical partition that you plan to assign to the shared memory pool is running.
Verify that you are a super administrator or an operator of the HMC.

When you assign a paging VIOS partition to the shared memory pool and both paging VIOS partitions have access to the same paging space devices, those paging space devices become common.

To assign a paging VIOS partition to the shared memory pool, complete the following steps from the HMC:

In the navigation pane, expand Systems Management and click Servers.
In the work pane, select the server on which the shared memory pool is configured.
From the Tasks menu, click Configuration > Virtual Resources > Shared Memory Pool Management. The Pool Properties window is displayed.
Click the Paging Space Devices tab.
Click Add/Remove Devices. The Shared Memory Pool wizard is displayed.
Follow the steps in the Shared Memory Pool wizard to assign a paging VIOS partition to the shared memory pool.

After you assign a second paging VIOS partition to the shared memory pool, complete the following steps:

If no common paging space devices are assigned to the shared memory pool, assign them to the shared memory pool. For instructions, see Adding and removing paging space devices to and from the shared memory pool.
Configure the logical partitions that use shared memory to use the paging VIOS partition that you assigned to the shared memory pool. For instructions, see Changing the paging VIOS partitions assigned to a shared memory partition.
