Network Issue

stefano colombo_1 — Thu, 30 Sep 2010 13:40:31 GMT

I'm setting up a P4000 cluster with 5 nodes.
we have 2 HP Procurve 2910al-24g switches .
We created a VLAN to be used for iscsi.
We configured jumbo frame on that vlan as well as on the P4000 ethernet ports .
Flow control is enabled

A trunk of two port has been set between the two switches.

With such configuration we configured each P4000 node with ALB bound.

Then we tried to create a management group but got many failures ( recv errors and similar ) .

At the end found that disconnecting a P4000 port on each node .

Is there something wrong in our settings ?
Can anyone provide a guide on this ?
thanks

I know you probaby don't need to do this for it to work "properly", but can you confirm communications between the switches?

assign an ip address to vlan 10 on each switch, then from the cli, ping the other one.

Based on the running config, I take it your p4000 nodes are plugged into ports between 1 and 14 (as well as the servers attaching to them..)

Can you paste the output from show vlans..

each p4000 has one nic on on eswitch each .
P4000 and servers are connected to ports 1-14
If I don't make a bound and assign an IP to each p4000's NIC I see no lost packets .

As soon as I make a bound some ping were lost.

Also when I try to create a MG I got the errors

Cannot connect to the switches now
thanks
