For AIX, it's default distritubion mode (what it implements the hash against) is the destination IP address. In other words, it has the same quasi-load-balancing as etherchannel. If the switch is also hashing on the destinitation IP address, then you will get little or no inbound (to the tsm server) load balancing since all tsm nodes send to the same destination - the tsm server. The only true load-balancing distribution policy is round-robin, which I believe should NOT be used with a switch - only servers connected back-to-back.
