Maximum number of volumes to resynchronize concurrently

For the configurations that have sufficient I/O bandwidth, multiple volumes can be resynchronized simultaneously, to complete resynchronization sooner. This parameter specifies the number of volume pairs that are resynchronized simultaneously. A volume pair consists of a source volume and its snapshot (or mirror) volume.

The default is 1, which means that volume pairs are resynchronized one at a time. Accept the default if the I/O bandwidth in your clients and disk storage cannot support simultaneous synchronization of volumes. A major factor in I/O bandwidth is the number and speed of HBAs on each client.
