Dynamically managing physical adapters

You can use the Integrated Virtualization Manager to change the physical adapters that a running partition uses.

You can change the physical adapter settings for a logical partition at any time if the partition is capable of dynamic I/O adapter changes.
Note: You cannot assign a physical adapter to an IBM® i partition. Because there is no physical I/O assigned to an IBM i partition, the partition is not capable of dynamic I/O adapter changes.

When making dynamic I/O adapter changes, consider the following restrictions:

  • You might lose data if you remove a physical adapter from a running partition.
  • You cannot assign a physical adapter to another partition if it is being used by the operating system of the partition to which it is currently assigned. If you attempt to reassign the adapter, an error message is displayed. You must unconfigure the device by using the tools of the appropriate operating system before you can change the partition assignment for the adapter.

Before you start, ensure that the Integrated Virtualization Manager is at version 1.5 or later. To update the Integrated Virtualization Manager, see Viewing and updating the code level of the Integrated Virtualization Manager management partition.

To dynamically change the adapters that a running logical partition uses, complete these steps in the Integrated Virtualization Manager:
  1. If no client partitions exist, begin at the step 6.
  2. In the navigation area, select View/Modify Partitions under Partition Management. The View/Modify Partitions page is displayed.
  3. Select the partition for which you want to change the physical adapter assignments.
  4. From the Tasks menu, click Properties. The Partition Properties page is displayed.
  5. On the General tab, verify that Yes is the value for I/O adapter DLPAR Capable. You might need to click Retrieve Capabilities to verify this value. If No is the value for Processing DLPAR Capable, then you cannot dynamically change the physical adapters that the partition uses while the logical partition is active.
  6. From the navigation areas, select View/Modify Physical Adapters under I/O Adapter Management.
  7. Select the adapter for which you want to change the partition assignment and click Modify Partition Assignment.
  8. Select the partition to which you want to assign the physical adapter and click OK. If you want to make this adapter available to any client partition, including those not yet created, select None for the New partition value.
