When a GAD pair is suspended, the suspend type is displayed in Status field of the Storage Navigator View Pair Properties window. The suspend type is not displayed by CCI.

The following table lists and describes the GAD suspend types.

Suspend type Volume Description
Primary Volume by Operator P-VOL The user suspended the pair from the primary storage system. The S-VOL suspend type is "by MCU".
Secondary Volume by Operator P-VOL

S-VOL

The user suspended the pair from the secondary storage system.
by MCU S-VOL The secondary storage system received a request from the primary storage system to suspend the pair. The P-VOL suspend type is Primary Volume by Operator or Secondary Volume by Operator.
by RCU P-VOL The primary storage system detected an error condition at the secondary storage system, which caused the primary storage system to suspend the pair. The S-VOL suspend type is Secondary Volume Failure.
Secondary Volume Failure P-VOL

S-VOL

The primary storage system detected an error during communication with the secondary storage system, or an I/O error during update copy. In this case, the S-VOL suspend type is usually Secondary Volume Failure. This suspend type is also used when the number of paths falls below the minimum number of paths setting on the Add Remote Connection window.
MCU IMPL P-VOL

S-VOL

The primary storage system could not find valid control information in its nonvolatile memory during IMPL. This condition occurs only if the primary storage system is without power for more than 48 hours (that is, power failure and fully discharged backup batteries).
Initial Copy Failed P-VOL

S-VOL

The pair was suspended before the initial copy operation was complete. The data on the S-VOL is not identical to the data on the P-VOL.
