The following table describes the Thin Image Advanced pair status definitions, the S-VOL access for the status, and the corresponding status that is shown in HDvM - SN.

S-VOL access |
Status shown in HDvM - SN |
|---|---|---|---|
|
COPY |
The storage system has accepted an operation for creating a pair. The P-VOL accepts read/write operations, but the SVOLs do not accept read/write operations. | Read/write disabled. | COPY(PD) |
| PAIR | The volumes are paired. The S-VOLs do not accept read/write operations. | Read/write disabled. | PAIR |
| PFUL | The usage rate of the DP pool exceeds the depletion threshold when the pair status is PAIR. | Read/write disabled. | PFUL |
| PSUP | The pair with the snapshot attribute is in the process of being split. The S-VOLs do not accept read/write operations. After the pair is split, the pair status is automatically changed to PSUS or PFUS. | Read/write disabled. | PSUS(SP) |
| PSUS | The pair with the snapshot attribute is split. The S-VOLs can accept read/write operations. When the pair status is PSUS or PFUS, the storage system records differential data between the P-VOL and S-VOLs so that you can immediately resynchronize the pair. | Read/write enabled (Can be mounted to the S-VOL.) | PSUS |
| PFUS | The usage rate of the DP pool exceeds the depletion threshold when the pair status is PSUS. | Read/write enabled. | PFUS |
| COPY | Normal Copy is in progress (snapshot data is being deleted). The S-VOLs do not accept read/write operations. | Read/write disabled. | COPY(RS) |
| RCPY | The pair accepted Reverse Copy operation and the pair is in the process of being copied for pair restoration.2 The P-VOL and S-VOLs do not accept read/write operations. | Read/write disabled (Read/Write disabled also for P-VOL) | COPY(RS-R) |
| CPYP | For the pair with snapshot attribute, assigning an S-VOL, releasing the assignment of the S-VOL, or changing the assignment of the S-VOL is in progress. The S-VOLs do not accept read/write operations. When the processing is complete, the pair status returns to the status before the processing. | Read/write disabled | COPY(SP) |
| SMPP1 | The pair is in the process of being deleted. You cannot perform pair tasks when the pair is in this status, and you cannot assign an S-VOL to snapshot data, release an assignment, or change an assignment. When the processing is complete, volumes are unpaired. | Read/write disabled | SMPL(PD) |
|
PSUE |
The storage system suspended the Thin Image Advanced pair due to a failure. The P-VOL continues accepting read/write operations, but S-VOLs do not accept read/write operations. Snapshot data is lost. |
Read/Write disabled. |
PSUE |
|
Notes: 1. SMPP is displayed if the -key detail option is specified for the raidcom get snapshot command. 2. Starting time of the copy depends on numbers of pairs and your system environment. |
