10.2.0.5
10.2.0.6

core switch to core switch communication is ok.

problem is core sw1 not pinging to core sw2 access switch

I don't see IP routing enabled anywhere in the switch configs. Are you routing between subnets through another device (like a firewall or router)?

[Laurent_Rillet]

For me, on these switch you need :
configure iproute add default 10.3.0.2

On the switches other side
configure iproute add default 10.2.0.2

On core :
each must have other core as default route next hop.

You may need to enable ipforwarding on your vLANs...
