I would like to know how redundant ports (FED) work when one port fails.
For e.g. 1A and 2A are said to be in pairs/redundant ports. Will 2A take over if 1A fails? If we need the host to be zoned to both 1A and 2A to have redundant paths, why they are said to be in pairs? Cant we use 1A and 6B (any other port) to have same redundant configuration?
