Paging space devices on systems that are managed by the Integrated Virtualization Manager
You can learn about the paging storage pool on systems that are managed by the Integrated Virtualization Manager.
When you create the shared memory pool, you assign a paging storage pool to the shared memory pool. The paging storage pool provides the paging space devices for the shared memory partitions that are assigned to the shared memory pool.
When you activate the shared memory partition, the Integrated Virtualization Manager allocates a paging space device from the paging storage pool to the shared memory partition that best fits the size requirements of the shared memory partition.
- For AIX® and Linux shared memory partitions, the paging space device must be at least the size of the maximum logical memory size of the shared memory partition.
- For IBM® i shared memory partitions, the paging space device must be at least the size of the maximum logical memory size of the shared memory partition plus 8 KB for every megabyte.
The Integrated Virtualization Manager automatically creates a paging space device for the shared memory partition in one or more of the following situations:
- No paging space devices exist in the paging storage pool.
- No paging space devices that are in the paging storage pool meet the size requirements of the shared memory partition.
- All of the paging space devices in the paging storage pool are assigned to other shared memory partitions.
The Integrated Virtualization Manager allocates only one paging space device to a shared memory partition at a time. If you do not assign a paging storage pool to the shared memory pool, you need to assign a minimum of one paging space device to the shared memory pool for each shared memory partition. After you create the shared memory pool, you can add or remove paging space devices to or from the shared memory pool as needed.
