Changing the shared memory pool size by using the Integrated Virtualization Manager
You can use the Integrated Virtualization Manager to increase or decrease the amount of physical memory that is assigned to the shared memory pool. You can perform this task if the managed system supports the PowerVM® Active Memory™ Sharing technology for using shared memory.
Use any role
other than View Only to perform this task. The
View Only role can view the properties, but it cannot change them.
You can increase the size of the shared memory pool only if enough physical memory is available in the system to do so. If you want to assign more memory to the pool than is available, you must decrease the amount of assigned memory for one or more partitions that use dedicated memory or you must add more physical memory to the server.
To change the size of the shared memory pool, complete the
following steps in the Integrated Virtualization Manager:
- From the navigation area, select View/Modify Shared Memory Pool under Partition Management.
- In the Pending field for Assigned memory, specify the amount of memory that you want to assign to the shared memory pool.
- In the Pending field for Maximum memory, specify the maximum amount of physical system memory that the shared memory pool can have for distribution to shared memory partitions. The pending maximum amount of memory for the shared memory pool must be equal to, or greater than, the pending assigned amount of memory. Although you can specify a maximum value that is greater than the total amount of memory installed in the system, the assigned memory cannot be changed to a value higher than what is available on the system.
