Evening all! We've having some ongoing weird iSCSI problems that we're trying to track down. Specifically, we're logging a huge amount of disconnects in our ESX hosts that connect to our EMC Clariion storage arrays. Our VMs are still running well despite this, but the sheer number of errors is getting somewhat alarming.
Our core is a pair of Nexus 5548s with a few 2200 Fabric Extenders thrown in the mix. We're using 10-gig TwinAx and -SR Fiber connections. iSCSI is on its own dedicated vlan and mapped using standard access ports to each ESX host. I'm not seeing any significant errors on the interfaces themselves, and the utilization is well below 10gigs. The CPU on the EMC isn't high at all, but still, something's behaving strangely. So my question is...are there any apps that will listen on my iSCSI vlan and detect any weird network anomalies? I'd like something iSCSI specific. Basically I'd like to make sure there aren't any strange traffic floods, responses from multiple IPs, stupid RSTs, and so forth. Worst case I'll throw up a Wireshark box, span the traffic and eyeball it, but automated tools are always much easier. Any help or tips are much appreciated. - Mike -- 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0 _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
