v Every logical partition must have access to an alternate IPL IOP/device. It can be dedicated or
switchable.
v Every logical partition must have a load source disk.
To add a new logical partition follow these steps:
1. Power down all of the secondary partitions.
2. Perform an initial program load (IPL) of the entire system in manual mode to dedicated service tools
(DST).
3. Verify that the secondary partitions are powered down.
4. Remove the processing resources from the primary partition or secondary partitions for the new
secondary partition.
5. Remove the I/O resources from the primary partition or secondary partitions for the new secondary
partition.
6. At the Work with System Partitions display, select option 5 (Create a new partition).
7. Press F9 for a list of limits.
8. Provide the required information for:
v Partition name. (A partition name can be any word (except PRIMARY), not exceeding 8 characters
(A - Z and 0 - 9)).
v Number of partition processors.
v Size of main storage (MB).
v Partition interactive performance.
v Connect to system Virtual OptiConnect.
v Connect to system HS-Connect (High Speed Link).
9. Press Enter.
If you have entered a value that is out of range, you will receive a message to change your numbers.
You can also adjust limits for the following:
