Specifies the delay in milliseconds between synchronizing successive sets of regions as specified by the value of the previous parameter (Sync region size in MB). You can use this option to change the effect of synchronization on system performance.

The default is 0 milliseconds (no delay). Increasing this value slows down synchronization. It also reduces the competition for I/O bandwidth with other processes that may access the volume at the same time.

This option is the same as the slow=iodelay parameter on the VxVM vxsnap command. For more details on the slow=iodelay parameter, see the Veritas Volume Manager Administrator's Guide.
