Pair operations history
The following table describes the operations displayed in the History window.
Operation | Description |
Pair definition | A pair was defined. |
Paircreate Start | Creation of the pair was started. When you use UR with TC and if you specify Entire Copy for the Delta Resync Failure option (Edit Mirror Options window), Paircreate Start is displayed because all P-VOL data is copied to the S-VOL if delta resync is not executed. When you use UR with GAD, specifying Entire Copy for the Delta Resync Failure option is invalid. |
Paircreate Complete | Creation of the pair was finished. When you use UR with TC and if you specify Entire Copy for the Delta Resync Failure option (Edit Mirror Options window), Paircreate Complete is displayed because all P-VOL data is copied to the S-VOL if delta resync is not executed. When you use UR with GAD, specifying Entire Copy for the Delta Resync Failure option is invalid. |
Pairresync Start | Restoring of the pair was started. |
Pairresync Complete | Restoring of the pair was finished. |
Pairsplit-r Start | Splitting (Suspending) of the pair was started. |
Pairsplit-r Complete | Splitting (Suspending) of the pair was finished. |
Pairsplit-r(Failure) | The pair was split (suspended) because of a failure. |
Pairsplit-S Start | Release of the pair was started. |
Pairsplit-S Complete | Release of the pair was finished. |
Status Change by MCU(SMPL to COPY) | The status of the pair was changed from SMPL to COPY because of an operation from the primary storage system. |
Status Change by MCU(SMPL to PAIR) | The status of the pair was changed from SMPL to PAIR because of an operation from the primary storage system. |
Status Change by MCU(COPY to PAIR) | The status of the pair was changed from COPY to PAIR because of an operation from the primary storage system. |
Status Change by MCU(COPY to PSUS/PSUE) | The status of the pair was changed from COPY to PSUS or PSUE because of an operation from the primary storage system. |
Status Change by MCU(PAIR to PSUS/PSUE) | The status of the pair was changed from PAIR to PSUS or PSUE because of an operation from the primary storage system. |
Status Change by MCU(PAIR to SMPL) | The status of the pair was changed from PAIR to SMPL because of an operation from the primary storage system. |
Status Change by MCU(COPY to SMPL) | The status of the pair was changed from COPY to SMPL because of an operation from the primary storage system. |
Status Change by MCU(PSUS/PSUE to SMPL) | The status of the pair was changed from PSUS or PSUE to SMPL because of an operation from the primary storage system. |
Status Change by MCU(PSUS/PSUE to COPY) | The status of the pair was changed from PSUS or PSUE to COPY because of an operation from the primary storage system. |
Status Change by RCU(Pairsplit-r Start) | The status of the pair was changed because an operation for splitting a pair started at the secondary storage system. |
Status Change by RCU(Pairsplit-r Complete) | The status of the pair was changed because an operation for splitting a pair finished at the secondary storage system. |
Status Change by RCU(PSUS/PSUE to SMPL; Pairsplit-S Start) | An operation for releasing a pair has been started at the secondary storage system. The status of the pair will change from PSUS or PSUE to unpaired (SMPL). |
Status Change by RCU(COPY to SMPL; Pairsplit-S Start) | An operation for releasing a pair has been started at the secondary storage system. The status of the pair will change from COPY to unpaired (SMPL). |
Status Change by RCU(PAIR to SMPL; Pairsplit-S Start) | An operation for releasing a pair has been started at the secondary storage system. The status of the pair will change from PAIR to unpaired (SMPL). |
Status Change by RCU(Pairsplit-S Complete) | The status of the pair was changed because an operation for releasing a pair finished at the secondary storage system. |
Ready for Delta resync | A pair became ready for delta resync. |
Ready for Delta resync(Failure) | The failure occurred with the pair which was ready for delta resync. |
Status Change for Delta resync | The status of the P-VOL was changed to HOLD because of a delta resync operation. |
Status Change by MCU(SMPL to HOLD) | The status of the pair was changed from unpaired (SMPL) to HOLD because of an operation from the primary storage system. |
Status Change by MCU(HOLD to PAIR) | The status of the pair was changed from HOLD to PAIR because of an operation from the primary storage system. |
Status Change by MCU(HOLD to COPY) | The status of the pair was changed from HOLD to COPY because of an operation from the primary storage system. |
Status Change by MCU(HOLD to SMPL) | The status of the pair was changed from HOLD to unpaired (SMPL) because of an operation from the primary storage system. |
Status Change by RCU(HOLD to SMPL; Pairsplit-S Start) | An operation for releasing a pair has been started at the secondary storage system. The status of the pair will change from HOLD to unpaired (SMPL). |
Status Change to HOLD | The status of the S-VOL was changed to HOLD because of a delta resync operation. |
