The following document describes the procedure to upgrade the Microcode on the IBM p590 systems. Upgrading the microcode requires the each frame in the pair to be powered-down, causing all systems running on the frame to be shutdown. Since production databases are running on each frame, a microcode upgrade requires the coordination of the AIX system administration team, DBA's, and application administrators.

1. The first phase of this process is to upgrade the HMC associated with the p590 frames.
2. Then failover all production systems to the alternate frame. Non-production systems will not be failed over, they will simply be shutdown.
3. Next, power off the p590 frame and perform the Microcode upgrade.
4. After microcode upgrade is complete and verified, power up the p590 and restart all systems.
5. Failback all production systems and test.
6. Repeat this process for the second p590 frame.
