Prerequisites
- The communication is normal between the two storage systems in the remote replication relationship.
- The two storage systems in the remote replication relationship support capacity expansion in split state.
- The LUNs for which you want to expand capacity are in normal state.
- The storage pool where the primary and secondary LUNs reside has sufficient space.
Perform capacity expansion for both the primary and secondary LUNs. The primary and secondary LUNs should have the same capacity after the expansion.
Procedure
- Split the remote replication pair.
NOTE:If the remote replication pair for which you want to perform capacity expansion has been added to a consistency group, split the consistency group first and synchronize the consistency group manually after the capacity expansion. - Expand the capacity of the primary LUN and the secondary LUN respectively.
NOTE:For details about how to expansion the capacity of a LUN, see section Expanding a LUN in the Capacity Expansion Guide of the corresponding product model. - Scan the primary LUN on the host.
- Start the remote replication pair synchronization manually.
