Adding a paging VIOS partition to the shared memory pool

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 begin

Before you assign a paging VIOS partition to the shared memory pool, complete the following steps:
  1. Verify that only one paging VIOS partition is currently assigned to the shared memory pool.
  2. Verify that the paging VIOS partition that is currently assigned to the shared memory pool is running.
  3. Verify that the VIOS logical partition that you plan to assign to the shared memory pool is running.
  4. Verify that you are a super administrator or an operator of the HMC.

About this task

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.

For more information about managing shared memory pools, see Managing shared memory pools.

What to do next

After you assign a second paging VIOS partition to the shared memory pool, complete the following steps:
  1. 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.
  2. 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.
