TIP: A volatile storage system failure is a condition in which storage system memory enters a
volatile state due to 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.
Performing primary site storage system maintenance
The following are the procedures for primary site storage system maintenance.
The procedure below applies when you perform a failover to remote site 1. To perform a failover
to remote site 2, replace remote site 1 with remote site 2 in the procedure.
