Performing DLPAR Physical IO Moves with Enhanced HMC GUI

Question & Answer


Question

How to move a physical IO adapter from one partition to another using the enhanced UI?

Answer

The enhanced UI does not support dynamic logical partitioning (dlpar) move. The user must first remove the adapter from the current owning partition then add the adapter to the target. The operating system device needs to be "varied off' prior to removing the adapter from the owning partition.

1. Remove the adapter from current partition.

From the partition signon, Vary off the resource

Select Resources > All partitions.

Select the partition that owns the resource now.

select partition


Then, click on the Physical I/O Adapters:

Properties - physical IO

Select the I/O adapter to remove.


select adapter

Click Action > Remove Adapter.

At the prompt "The selected adapter will be removed. Do you want to continue?" Click OK

Click the Save button at the top of the physical I/O Adapter panel to apply the changes.
This will remove the adapter from the partition.

Note: The device would need to be varied off prior to removing the adapter.

2. Add the adapter to the target partition.


Select the target partition

Select Physical I/O Adapters:

Click Add Adapter.
select physical adapters



Select the adapter to add, then click OK:
add phys IO

Click the Save button at the top of the physical I/O Adapter panel to apply the changes

The IO adapter should now report in to the target partition.
