Device Manager - Storage Navigator pair status names and descriptions

The following table lists HDvM - SN pair status names and descriptions, including the level of S-VOL access.

HDvM - SN status	CCI status	Description	P-VOL access	S-VOL access
SMPL	-	The volume is not part of a pair.	Read/write enabled	Read/write enabled
SMPL(PD)	-	The pair is in the process of being deleted.	Read/write disabled⁴	Read/write disabled
COPY(PD)²	COPY²	The paircreate initial copy is in progress.¹ The storage system accepts read/write to the P-VOL but does not accept write operations to the S-VOL.	Read/write enabled	Read only
PAIR	-	The initial copy operation has completed and the volumes are paired. The storage system performs update copy operations. Data consistency is not ensured for SI pairs in this status.	Read/write enabled	Read only
COPY(SP)²	COPY²	The pair is in the process of being Steady Split. The storage system: Copies the differential data to the S-VOL.¹ The data in the S-VOL is identical to the data in the P-VOL. Splits the pair.	Read/write enabled	Read only
PSUS(SP)²	PSUS²	The pair is in the process of being Quick Split. The differential data is copied to the S-VOL in the background.¹ You cannot delete pairs in this status.	Read/write enabled	Read/write enabled
PSUS	PSUS³	The pair has been split. The storage system stops performing update copy operations but accepts write I/Os for the S-VOL. The storage system keeps track of updates to split P-VOLs and S-VOL so that you can Quick Resync.	Read/write enabled	Read/write enabled
COPY(RS)²	COPY²	The pairresync CCI command is in progress. The storage system does not accept write I/Os for S-VOL.¹ Resynchronizing split pairs copies only the differential data to the S-VOL.	Read/write enabled	Read only
COPY(RS-R)²	RCPY²	The reverse pairresync CCI command is in progress. The storage system copies only the S-VOL differential data to the P-VOL. The storage system does not perform update copy operations during a Reverse Copy or a Quick Restore. The storage system does not accept write I/O operations to S-VOL.¹	Read/write disabled	Read only
PSUE	-	The storage system does the following: Suspends the pair. Continues accepting read and write I/Os to the P-VOL. Stops update copy operations to the S-VOL. Marks the P-VOL as differential data. Resynchronizing a pair copies the P-VOL to the S-VOL.	Read/write enabled	Read only
Notes: The starting time of the copy depends on the numbers of pairs and the storage system environment. The pair status is displayed in the format of `screen pair status`/`CCI pair status`. CCI display is as follows: P-VOL: PSUS S-VOL: SSUS If the status was Read/write enabled before the transition to SMPL(PD), it is Read/write enabled.
