Changing the ownership of a bus

 

A logical partition can own a system input/output (I/O) bus in one of two ways. It can own bus dedicated, or it can own bus shared.

When a logical partition owns a bus with own bus dedicated status, no other logical partition can share it.

If a logical partition owns a bus with the status of own bus shared, the partition can share the bus with another logical partition. However, that other logical partition must add that bus with the status of use bus shared.

Before you change a bus ownership type to own bus dedicated, first add all of the resources under that bus to that partition. When you change a bus' ownership type to own bus shared, resources under that bus can now be removed. Other logical partitions (primary partition and all secondary partitions) can now use these resources.

To change the ownership for a bus using My Connections, follow these steps:

1. In iSeries™ Navigator, expand My Connections or your active environment.

2. Select the primary partition of the system.

3. Expand Configuration and Service and select Logical Partitions.

4. Right-click the Logical Partition and select Configure Partitions. You are now working in the Configure Logical Partitions window.

5. Right-click the bus for which you want to change ownership and select Properties.

6. Select the Partitions page.

7. Select the partition that owns the bus in Owning logical partition, and then select the ownership type in Sharing. If the ownership type is shared, the partitions that share the bus appear in the list. Click Help if you need more information on these options.

8. Click OK.
