Snapshot resynchronization (started by
syncstart, or by specifying
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.
To recover from I/O errors during resynchronization
vxsnap [-b] [-g diskgroup
] syncstart volume
