A Unity storage system is installed with 10 Gb optical SFPs in CNA ports 4 and 5 of both Storage Processors. The storage administrator has had a request from a user to connect to the storage system through Fibre Channel.
How can the administrator reconfigure the CNA ports for 16Gb Fibre Channel SFPs?
Once you set the network protocol on the CNA ports you cannot switch to a different network protocol.
