how to check the switch if its using Enhanced zoning or not ?

I think that will work, but as I do not have a test environment where I can run that. And I say it will work with caveats. First, you commit to vsan 10 and then activate the zoneset on vsan 100. I assume this is a typo.

I prefer a more direct method that documents explicitly what I am doing. I'll show you another way that I think is better since it incorporates the vsan in the zone command.

switch(config)# zone name UX120_LPFC0_SYM0441_9AB vsan 10
switch(config-zone)# member pwwn 10000000c93abe16
switch(config-zone)# member pwwn 50060482ccb4fe68

While this does not seem major, this way allocates the zone to the vsan directly and allows you to create many zones all in a row without having to "commit" each one individually. Once you have all of them created, you activate the zoneset as follows:

switch(config)# zoneset name Production_A_ACTIVE vsan 10
switch(config-zoneset)# member UX120_LPFC0_SYM0441_9AB

switch(config-zoneset)# zoneset activate name Production_A_ACTIVE vsan 10

As you will no doubt see, there are a number of ways to do the same thing. Pick one that works for you. My caution is to always be explicit in what you are doing and do not ever assume that a command will be acting against a default zoneset.
