NOTE: The term "storage system failure, with information lost from memory," indicates a failure
that causes the loss of information in memory. In such a failure, the copy pair information and the
data are completely lost, so the hardware information must be reconfigured.
This section provides maintenance and troubleshooting procedures for 3DC Multi-Target (Cnt Ac-J
Z x Cnt Ac-J Z) configurations.
The figures in the procedures in this section use the following legend.
The bullet lists under the figures in the procedures show the commands that must be executed.
