Recovering from I/O errors during resynchronization

Snapshot resynchronization (started by vxsnap syncstart, or by specifying sync=on to vxsnap) stops if an I/O error occurs, and displays the following message on the system console:

VxVM vxsnap ERROR V-5-1-6840 Synchronization of the volume 
volume stopped due to I/O error

After correcting the source of the error, restart the resynchronization operation.
