Adding and removing paging space devices to and from the shared memory pool

Before you add a paging space device, complete the following tasks:

1. Configure the paging space device to the Virtual I/O Server (VIOS) logical partitions (hereafter referred to as paging VIOS partitions) that are assigned to the shared memory pool. If you plan to use logical volumes as paging space devices, then create the logical volumes. For instructions, see Creating a virtual disk for a VIOS logical partition by using the HMC.
2. Verify that all paging VIOS partitions are running.

Before you remove a paging space device, complete the following tasks:

• If no logical partition that uses shared memory (hereafter referred to as a shared memory partition) is using the paging space device, verify that the paging space device is inactive.
• If a shared memory partition is using the paging space device, verify that the shared memory partition is shut down.
• Verify that all paging VIOS partitions are running.

You must be a super administrator or operator of the HMC to add and remove paging space devices to and from the shared memory pool.
