Answer 1

Exactly, the 6500 config is fine, probably the NETAPP is not active or passive and it's just ON that won't work
show lacp 248 neighbor will show if you have a neighbor and if the LACP id is the same on both ports
Core1#sh lacp 2 neighbor
Flags:  S - Device is requesting Slow LACPDUs
        F - Device is requesting Fast LACPDUs
        A - Device is in Active mode       P - Device is in Passive mode
Channel group 2 neighbors
