- ONTAP 9
The Data ONTAP DSM supports both FC and iSCSI paths to the same LUN for clustered Data ONTAP.
The DSM does not support both FC and iSCSI paths to the same LUN for Data ONTAP operating in 7-Mode. Because ALUA is required for FC paths, and ALUA is not supported for iSCSI paths to 7-Mode LUNs. All paths must have the same ALUA setting. But can still have FC paths to some 7-Mode LUNs and iSCSI paths to other 7-Mode LUNs.
