You can use the Integrated Virtualization Manager to
change the physical adapters that a running logical 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
logical 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 logical 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:
- If no client logical partitions exist, begin at the step 6.
- In the navigation area, select View/Modify Partitions under Partition
Management. The View/Modify Partitions
page is displayed.
- Select the logical partition for which you want to change
the physical adapter assignments.
- From the Tasks menu, click Properties. The Partition Properties page is displayed.
- 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 logical partition uses while the logical
partition is active.
- From the navigation areas, select View/Modify
Physical Adapters under I/O Adapter Management.
- Select the adapter for which you want to change the partition
assignment and click Modify Partition Assignment.
- Select the logical partition to which you want to assign
the physical adapter and click OK. If
you want to make this adapter available to any client logical partition,
including those not yet created, select None for
the New partition value.
