The data replication function realized by HW may cause errors given below, in addition to ordinary
HW faults. These errors can be checked from the iSM Client screen. These errors may abnormally
stop ReplicationControl commands.
(1) Copy Fault
Detecting a copy fault
If copy operation between MV and RV is not executed normally due to a connection failure
between them, a transition to the following states may occur depending on the timing and type of
the failure.
•
Separate state due to a failure (failure separation)
•
Suspend state due to a failure (abnormal suspend)
If a transition occurs to one of the states above, you can use Replication Screen to check the status
of the copy fault (Figure 2-9).
