SAN Copy provides one-time migration of Block resources from a 3rd-party array, using either iSCSI or FC connections. When using FC, note that SAN Copy must use different ports than the FC ports which are designated for Synchronous Replication. This is true even if Synchronous Replication is not actively being used.
To lessen the impact of SAN Copy migrations on other host activity, consider reducing the number of host connections on the FC ports used for SAN Copy.
