I am troubleshooting a STP looping issue with a iSCSI SAN environment, many servers in the
server farm share the SAN through both SAN side switches (see the diagram attached), I am a cisco guy and these SAN side switches are Procurve, but all flat lan.
Customer think 192.168.130.0/24 and 192.168.131.0/24 lan segments are will not talk to each other.
I think the link between the switches are the issue, but they need that for redundancy isn't it. How can I prevent looping and keep the interswitch link.
or any other solution.
You only have one connection between the 2 switches and that should not cause any loop. Is there a way you can create a vlan on both HP switches and put all the ports in it and see if the problem goes away?
Sorry, not familiar with HP switches.
