I need to access our core switch from VDCx (Core_VDC) to VDCy (Admin_VDC) via L2 via SSH. Upon pinging, getting an RTO reply. This is just once device. Should be able to access without passing through the gateway since mgmt IP is within the same subnet.

it should work as expected, how is your mgmt0 interface connected ? where ?
VDC means 2 different devcies, that means, you need to have Layer 2 connectivity ?

mgmt0 is connected in the Server_VDC (Same device).
interface Ethernet5/31

This is just 1 physical device but different vdc.
I need to have a L2 connectivity in situation that FW is down. My only connection if ever FW is down is thru Core_VDC. No direct access to Admin_VDC in case our FW is down.

Trying to understand here, your management in VRF, that VRF need to extend to other VRF ?

Yes. Need to reach vrf management 172.26.1.6 from vrf management 172.26.1.8. They are on same device but different VDC.
