Determining the available physical memory on the destination server

You can determine whether the destination server has enough physical memory available to support the mobile partition and then make more physical memory available, if necessary, by using the Hardware Management Console (HMC).

1. Identify the amount of physical memory that the mobile partition requires:
   1. In the navigation pane, expand Systems Management > Servers.
   2. Click the source server on which the mobile partition is located.
   3. In the work pane, select the mobile partition.
   4. From the Tasks menu, click Properties. The Partition Properties window is displayed.
   5. Click the Hardware tab.
   6. Click the Memory tab.
   7. Record the dedicated minimum, assigned, and maximum memory settings.
   8. Click OK.
2. Identify the amount of physical memory that is available on the destination server:
   1. In the navigation pane, expand Systems Management and click Servers.
   2. In the work pane, select the destination server to which you plan to migrate the mobile partition.
   3. From the Tasks menu, click Properties.
   4. Click the Memory tab.
   5. Record the Current memory available for partition usage.
   6. Click OK.
3. Compare the values from steps 1 and 2. If the destination server does not have enough physical memory available to support the mobile partition, you can add more available physical memory to the destination server by performing one or more of the following tasks:
   • Dynamically remove physical memory from logical partitions that use dedicated memory. For instructions, see Removing dedicated memory dynamically.
   • If the destination server is configured with a shared memory pool, dynamically remove physical memory from the shared memory pool. For instructions, see Changing the size of the shared memory pool.
