Does anybody know the difference between FC aliases, Device Aliases and Global Aliases?
The FC (aka zone?) aliases are held in the running config on the switch and also seem to be specific to a VSAN.
Global Aliases seem to be a Fabric Manager thing - does the Fabric Manager server hold a database of aliases so that they are still recognised if you plug the device into a seperate physical SAN managed by the same FM server? Presumably if you connect via a different FM server to the same switch you would get different global aliases because you are connecting to a different database?
Device aliases seem to be an extension of fc aliases (in that they are stored in the running config) that are not VSAN specific and are not restricted to being used for zoning only.
Is that about right? Which of the above are people using and how do you find it? I'm still using fcaliases, purely because I haven't tried the others, although Device Aliases looks like an interesting option...
