Split Remote Replication Pair

This help page provides information to guide you through the procedure for splitting a replication pair. It contains the following topics:

• Overview

• Splitting a Pair

Overview    (back to top)

 Data is copied to an S-VOL at every update cycle until a pair is split.

• When the split is executed, all differential data accumulated in the local array is updated to the S-VOL

• After the split operation, write updates continue to the P-VOL but not to the S-VOL

After the Split Pair operation:

• S-VOL data is consistent with the P-VOL data at the time of the split. The S-VOL can receive read/write instructions

• The TrueCopy pair can be made identical again by re-synchronizing from the primary-to-secondary or secondary-to-primary

The pair must be in Paired status. The time required to split the pair depends on the amount of data that must be copied first to bring the S-VOL in line with the current P-VOL.
