[c-nsp] Cisco blade switch config

I have (2) Cisco blade switches running in redundant mode and each is
connected to the same HP ROOT switch on the other end. Each blade switch
has an LACP / Etherchannel link of 2 cables going to the HP root. STP
enabled on the Cisco's.
Noticed this on my Cisco-SW1 today:
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
1 Po1(SU) LACP Gi0/1(I) Gi0/2(I) Gi0/3(I)
Gi0/4(D) Gi0/5(D) Gi0/6(I)
Gi0/7(D) Gi0/8(I) Gi0/20(P)
Gi0/22(P)
This shows that gi 0/20 & 0/22 are in use and bundled in port channel as
they should be. My blade servers (gi 0/1 - 0/8) (some of which are down I
know) show (I) independant? Can anyone advise why?
Also, anyone know why a server like gi 0/1 for example will not talk on
multiple vlans?
I mean, they are set correctly on the HP, as I can ping out fine to those
vlans over there. Here is the Cisco config for those vlans. Cisco talks on
VLAN 1 fine. But Vlans 2 & 3, it doesnt.
