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.
