Change the IPL source for a logical partition

You can choose a separate initial program load (IPL) source (type) for each logical partition.

Each IPL source (A, B, C, or D) on a system with logical partitions works just like it would on a system without logical partitions.

For information on how each IPL source works and why you may need to change it, refer to IPL Type for more information.

Attention: Only a hardware service representative should use IPL source C. Only use IPL source C under the direction of your service representative. Severe data loss can occur with improper use of this function.

To change the IPL source for a partition, you should be working with the remote control panel. You need a Service Tools user ID with operations or administration authority to the System Partitions function in Dedicated Service Tools (DST) to work with the remote control panel.

Refer to Control panel functions for information on how to use the remote control panel and Change operating modes and IPL types for instructions on how to change the IPL source for a partition.
