Creating copy destination volumes
When creating copy destination volumes for remote copy, note the following:
The type of a copy destination volume must be OPEN, standard or TPV.
SDV or SDPV cannot be used as a copy destination volume for remote copy.
The size of a copy destination volume must be the same as that of copy source volume (the original volume).
For procedures about creating a copy destination volume, refer to "Create the volume" in the "ETERNUS SF Web Console Guide".
Setting of port mode
FC-RA ports or iSCSI-RA ports are required for REC.
Change the port mode of FC port or iSCSI port to Remote Adapter (RA).
Setting of copy paths
This setting is required for all storage systems that perform REC.
Create a data transmission path by combination of FC-RA ports or iSCSI-RA ports.
Setting of REC buffers
When using the Consistency mode, REC buffers are used. Up to four REC buffers can be set. Set the REC buffer size for both data transmission and reception units. You can use a single buffer for unidirectional data transfer only. Therefore, if you use the bidirectional data transfer, you must also set the buffer for reverse directional data transfer.
