Servicing your system in a high-availability environment

Learn how to service your system in a high-availability service environment using Live Partition Mobility (LPM) and the PowerHA® SystemMirror®.

Some system parts can be repaired or upgraded using concurrent maintenance, and do not require the system to be powered off during service. The repair or upgrade of other system parts require dedicated maintenance, and the system must be powered off during service. If the system is in a multi-system environment and dedicated maintenance is required, critical workloads can continue to run during service if the you are using LPM or PowerHA SystemMirror.
