Changing partition profile properties
You can change the properties of a partition profile using the Hardware Management Console (HMC). Changing the properties of a partition profile changes the resource amounts that are assigned to a logical partition when you shut down and restart the logical partition using the changed partition profile.
A partition profile stores the required number of processors, memory, and hardware resources assigned to that profile. Any partition profile property changes are not applied to the logical partition until you activate the partition profile.
If you plan to change a partition profile that specifies dedicated memory to a partition profile that specifies shared memory, be aware of the following actions:
- The HMC automatically deletes all of the physical I/O adapters specified in the partition profile. You can assign only virtual adapters to logical partitions that use shared memory.
- You must specify shared processors. Logical partitions that use shared memory must also use shared processors.
To change partition profile properties using the HMC, follow these steps:
- In the navigation pane, open , and click the name of the managed system.
- In the work pane, select the logical partition whose partition profile you want to change, click the Tasks button, and click .
- Select the partition profile that you want to change and click .
- Make the appropriate changes and click OK.
If you created at least one virtual fibre
channel adapter, complete the following tasks to connect the logical
partition to its storage:
- Activate the logical partition. When you activate the logical partition, the HMC assigns a pair of worldwide port names (WWPNs) to the virtual fibre channel adapter. For instructions, see Activating a logical partition.
- Restart the Virtual I/O Server (that provides the connection to a physical fibre channel adapter) or run the syscfg command. This enables the Virtual I/O Server to recognize the WWPNs of the virtual fibre channel adapter on the client logical partition For instructions, see Restarting Virtual I/O Server logical partitions using the HMC.
- Assign the virtual fibre channel adapter on the client logical partition to a physical port of a physical fibre channel adapter. For instructions, see Changing virtual Fibre Channel for a Virtual I/O Server using the HMC.
