There is either an IPL problem, a main storage dump problem, or a software error with a partition.

Perform any actions listed in the "Description/Action" column in the SRC table.

During the IPL or main storage dump of a partition, a complex problem was detected. The serviceable event view on the HMC has to be searched or the SRC history list on the HMC for the partition with the problem has to be analyzed in sequence. If the partition is a "Guest" partition, then the SRC history list of the "Hosting" partition must be analyzed.
