We recently had our FAS3210 installed and are now attempting to attach it to our XenServer 5.6 environment. I believe I'm correct in that the interface group type is lacp (even though when we run setup, it shows m. We've modified, rebooted and it still shows m). Our switch environment consists of (5) 3750 running 12.2. The switch configuration is as follow:
interface Port-channel31
switchport access vlan 193
switchport mode access
end
interface GigabitEthernet5/0/14
description ***NetApp Ctrl1 E0A***
switchport access vlan 193
switchport mode access
no cdp enable
channel-protocol lacp
channel-group 31 mode active
end
interface GigabitEthernet5/0/15
description ***NetApp Ctrl1 E0B***
switchport access vlan 193
switchport mode access
no cdp enable
channel-protocol lacp
channel-group 31 mode active
spanning-tree portfast
end
Within XenCenter, we attempt to create a new SR. We select Advanced StorageLink technology, provide a name and select NetApp as the storage system, provide the IP of the network interface storage group, use the same username/password as we use to access the controller via SSH and then I get the following error:

Scanning NetApp filer 10.1.93.50 for existing SRs...
Failed to connect to Netapp target
Check your settings and try again.
Ideas anyone?
