Cant ping a switch on 1 VLAN, can on the other.

Against my will , I replaced a Cisco Switch with an Extreme one. Im better versed at iOS then EXOS, but I can fumble my way through, and I'll need to get better as we are for some reason switching everything from Cisco to Extreme.

With all that out of the way, I set up an X460. Its got 2 VLANs on it, M200 and M201 . M200 is for the data vlan, 201 is the DMZ. From the SonicWALL, I try to ping the X460 that is directly plugged into it on 2 ports (1 for each VLAN) and I am able to ping 192.168.201.254. I am unable to ping 192.168.200.254

I am able to ping the VM hosts and VMs running on the 200 VLAN from the sonicwall and even from across the VPN. I can ping 192.168.200.254 from the servers and hosts plugged into the switches. I just cant ping it from anything above it.

Both VLANs are setup identically. Is there something glaringly obvious I'm glossing over?

FIXED

g-3-0 got it right, the Gateway was wrong. This switch was moved from 1 location to another, and the gateway was never changed. Thanks for all the help, upvotes, and downvotes. You guys rock.
