Pair Status
Simplex TCE pair is not created. Simplex volumes accept Read/
Write I/Os. Not displayed in TCE pair list on Navigator 2
GUI.
Synchronizing Copying is in progress, initiated by Create Pair or
Resynchronize Pair operations. Upon completion, pair
status changes to Paired. Data written to the P-VOL
during copying is transferred as differential data after
the copying operation is completed. Copy progress is
shown on the Pairs screen in the Navigator 2 GUI.
Paired Copying of data from P-VOL to S-VOL is completed.
While the pair is in Paired status, data consistency in the
S-VOL is guaranteed. Data written to the P-VOL is
transferred periodically to the S-VOL as differential
data.
Paired:split When a pair-split operation is initiated, the differential
data accumulated in the local array is updated to the S-
VOL before the status changes to Split. Paired:split is a
transitional status between Paired and Split.
Paired:delete When a pair-delete operation is initiated, the differential
data accumulated in the local array is updated to the S-
VOL before the status changes to Simplex. Paired:delete
is a transitional status between Paired and Simplex.
