v Installing new hardware.
v Adding a new logical partition.
v Change communication options.
v Deleting a secondary partition.

Changing a secondary partition name

Each logical partition has an 8 character unique identifier called the partition name. This identifier does not
have to be the same as the system name for each logical partition. When you change a secondary
partition name, the following rules apply:
v You cannot change the primary partition's name.
v Secondary partitions cannot share the same name.
v Names cannot exceed eight characters.
v Names must have at least one character (no all space names)
v Legal characters are A through Z, 0 through 9, and blanks.
You can change a secondary partition's name from dedicated service tools (DST) on the primary partition.
To change a secondary partition name, follow these steps:
1. Go to a DST menu.
2. From DST select option 11 (Work with system partitions) and press Enter.
3. Select option 3 (Work with partition configuration).
4. Use the cursor to choose the logical partition you want to change.
5. Select option 1 (Change partition name).
6. The Change Partition Name display appears. Type the new name for your logical partition and press
Enter.
7. The Confirm Changed Partition display appears. Press Enter to confirm your changes.

Changing bus ownership type for logical partitions

|
| A logical partition can own a system input/output (I/O) bus one of two ways, own bus dedicated, and 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.
