You need to ensure that the minimum requirements are met for a valid deployment of SnapMirror over Fibre Channel.
- You must use supported switches and compatible firmware.
Note: Supported switches and firmware versions for them are specified in
Requirements for SnapMirror over Fibre Channel transport (asnychronous, synchronous, and semi-synchronous modes) on
the NOW site.
- There must be at least one switch between source and destination.
- The SAN configuration must be homogenous with respect to the switch vendors.
- SnapMirror over Fibre Channel requires frame in-order delivery (IOD), even during the fabric reconfiguration process. Therefore, users need to turn on the IOD-related options on the Fibre Channel switch. For example, on a Cisco switch, configure VSAN with the in-order guarantee option.
- The path between source and destination must use dedicated switches or the Storage Area Network (SAN) must be configured such that SnapMirror traffic occurs in a dedicated zone. For Cisco switches, you can use the dedicated VSAN capability.
- You must use the native Fibre Channel fabric deployment, that is, no Fibre Channel over IP protocol conversions in the SnapMirror data path.
- Brocade Fibre Channel router in the SnapMirror data path is not supported.
- The storage system must be configured with FC NIC (X1024 or X1124).
