Thin Image pair status definitions

The P-VOL and V-VOL access columns in the following table indicate whether the volumes accept read/write.

For more information about the corresponding CCI pair command results, see CCI pair command results.

The following table describes the HTI pair status definitions, the S-VOL access for the status, and the corresponding status that is shown in CCI.


Pair status	Description	S-VOL access	Status shown in CCI
SMPL(PD)	The pair is in the process of being deleted. You cannot perform pair tasks when the pair is in this status, and you also cannot assign an S-VOL to snapshot data, release assignment, or change assignment.	Read/write disabled	SMPL
COPY	The storage system has accepted the paircreate CCI command. The P-VOL accepts read/write operations, but the S-VOLs do not accept read/write operations.	Read/write disabled	COPY
PAIR	The volumes are paired. The S-VOL does not accept read/write operations.	Read/write disabled	PAIR
PFUL	While the volumes are paired (“PAIR” status), you exceeded the data pool threshold.	Read/write disabled	PFUL
PFUS	While the pair is split (“PSUS” status), you exceeded the data pool threshold.	Read/write enabled	PFUS
PSUS	The pairsplit CCI command has completed. The Update Copy operation has stopped. The S-VOL can accept read/write operations. 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.	PSUS for P-VOLs SSUS for S-VOLs
RCPY	A Reverse Copy is in progress. The S-VOL does not accept read/write operations.* The starting time of the copy depends on the number of pairs in your storage system. Only S-VOL differential data is copied to the P-VOL. The Update Copy operation is not performed during Reverse Copy or Quick Restore.	Read/Write disabled	RCPY
PSUE	The pair is suspended. The S-VOL does not accept read/write operations.	Read/Write disabled	PSUE
* Starting time of the copy depends on numbers of pairs and your system environment.
