Table 31 Continuous Access Journal pair status (continued)
Secondary Primary Continuous Access Journal Pair Status Status
R/W enabled R enabled After Takeover, SSWS is the status of the S-VOL. With this status,
data can be written to the S-VOL. SSWS
•
SSWS is displayed by RAID Manager, from which the
horctakeover command is issued.
•
Remote Web Console displays this status as PSUS or PSUE.
R enabled R/W enabled If data in the journal volume exceeds 80-percent, pair status changes
to PFUL. The write data that inflows then is monitored during the Data
Overflow Watch. PFUL
PFUL status is displayed by RAID Manager. Remote Web Console
displays this status as PAIR.

Legend:
Accepted = Accepted and executed. When the operation terminates normally, the status changes to the indicated number.
Acceptable = Accepted but no operation is executed.
Rejected = Rejected and operation terminates abnormally.
Pairsplit of a Continuous Access Asynchronous volume is returned after verification of state transition
that waits until delta data is synchronized from P-VOL to S-VOL.
NOTE: In the case of the SSWS status after SVOL-SSUS-takeover execution, the pairresync
command (from P-VOL to S-VOL) is rejected because the delta data for S-VOL becomes dominant,
and its status is expected to be using the -swaps(p) option of pairresync. If the pairresync command
(from P-VOL to S-VOL) is rejected, confirm this special status using the -fc option of the pairdisplay
command.
Following table shows the relation of command acceptances for paired status and Business Copy.
