Pair status definitions

The following table lists and describes the Universal Replicator pair status names. The Device Manager - Storage Navigator pair status name and the CCI pair status name are both displayed in the Device Manager - Storage Navigator Status column. When the names are the same, the CCI pair status name is not displayed.

When checking the status of a pair, click File/Refresh to make sure the most recent information is displayed.


HDvM - SN status	CCI status	Description	P-VOL access	S-VOL access
(Unpaired- no HDvM - SN status)	SMPL	The volume is not assigned to a pair and is not in a journal.	Read/Write	Read/Write
COPY	COPY	The initial copy operation is in progress.	Read/Write	Read Only
PAIR	PAIR	The pair is synchronized. Updates to the P-VOL are duplicated on the S-VOL.	Read/Write	Read Only
HDvM - SN displays this status as PAIR	PFUL	If data in the journal volume exceeds the threshold (80 %), pair status changes to PFUL. The pair is not suspended; the copy operation continues. If the Inflow Control journal option is set to Yes when status changes to PFUL, host I/O is delayed because update I/O to the journal volume is delayed.	Read/Write	Read Only
PSUS	PSUS SSUS	The pair has been split by the user and the P-VOL and S-VOL are no longer synchronized. The primary and secondary systems keep track of journal data discarded during the split operation. When the operation is performed on the primary system, the status of both the P-VOL and S-VOL changes to PSUS. When the operation is performed on the secondary system, the status of the S-VOL changes to PSUS; the primary system detects this and changes P-VOL status to PSUS. SSUS is the S-VOL’s split status name. See also PSUS types and behaviors.	Read/Write	Read Only, but if you select Enable for Secondary Volume Write option then split pair from primary site, it is Read/Write (default is Disable).
PSUE	PSUE	The pair is suspended by the system due to an error; it is not synchronized. The primary and secondary systems keep track of journal data discarded during the suspension operation. The primary system keeps track of P-VOL tracks that are updated while the pair is suspended. When a Universal Replicator suspension condition is detected, the primary system changes P-VOL and S-VOL status to PSUE. If the secondary system detects the condition, it changes the S-VOL status to PSUE; the primary system detects this and changes P-VOL status to PSUE. See also PSUS types and behaviors.	HDvM - SN: Read/Write CCI: Read/Write if no error in P-VOL	Read Only
Suspending	(No equivalent CCI status)	The pair is not synchronized and in transition from the PAIR or COPY status to PSUS or PSUE status.	Read/Write	Read Only
Deleting (releasing)	(No equivalent CCI status)	The pair relationship is being deleted. When the operation completes, the status changes to unpaired.	Read/Write	Read Only
(No equivalent HDvM - SN status)	PFUS	This status results when the journal volume becomes full and suspends. Pair status changes from COPY, PAIR or PFUL to PFUS. The Universal Replicator pair is suspended and the copy operation stops. Make sure to review configuration of the remote path and journal volume. If a Dynamic Provisioning virtual volume (DP-VOL) is used as the Universal Replicator S-VOL, and the capacity of a pool-VOL is nearly full, Universal Replicator status becomes PFUS and the pair is suspended. If the journal option Inflow Control is set to Yes when status changes to PFUS, the pair is not suspended for the time set in the Data Overflow Watch field, even when the journal volume becomes full. During the time it takes for the journal data area to clear, the response to host I/O is delayed. See Changing options used by journals for more information on Data Overflow Watch.	Read/Write	Read Only, but if you select Enable for Secondary Volume Write option then split pair from primary site, it is Read/Write (default is Disable).
(No equivalent HDvM - SN status)	SSWS	After Takeover, SSWS is the status of the S-VOL. With this status, data can be written to the S-VOL.	Read Only	Read/Write
