Symptoms

A Sun Fire[TM] 12K/15K/20K/25K domain fails HPOST (Hardware Power On Self Test) with the following error.

The IOC (I/O Controller) on the I/O Board and the HBAs controlled by the IOC are taken out of the configuration by HPOST.

NOTE: If the SC configuration is SMS 1.4 or higher, CHS (Component Health Status) would set the IOC status to faulty and prevent it from being configured into the domain again at all (and HBAs).

The post log shows the failure:

As displayed above, IOC 1 has been failed, the cassettes and HBAs it controls were crunched by the failure, leaving them unusable. How do we correct this situation?
