Command to check the Ethernet Backend Switch on Isilon Cluster

[Anubhav Ahuja]

Hi All, 

Is there any command to run on the Isilon Cluster to get the information about what Ethernet Backend Switch we are connecting to and how many ports are left for expansion. I know we can run ibnetdiscover if there is infiniband switches on the cluster. But i couldn't find any command if there are Ethernet switches. 

Thanks in Advance

I don't know how to view info from the switch, but this will tell you where the nodes are connected and you should be able to deduce how many remaining ports there are:

"# isi_dump_fabric int-a" and "# isi_dump_fabric int-b"

It should return the switchport for each connected node. If you have any gen-6 nodes with 10G using 4x breakouts they'll show up as logical interfaces, but I don't have one in front of me to see how they are mapped out on the switch.

e.g.:

A2000, 10G

        {

            "uname": "Isilon OneFS v8.2.2.0 B_8_2_2_007(RELEASE)",
            "hostname": "node-20",
            "port_name": "mlxen1",
            "address": "10.1.2.30",
            "switchport": "99"
        }, 

F800, 40G

        {
            "uname": "Isilon OneFS v8.2.2.0 B_8_2_2_007(RELEASE)",
            "hostname": "node-21",
            "port_name": "mlxen1",
            "address": "10.1.2.31",
            "switchport": "27"
        },

Try running it again...I had the same happen on one of my clusters but it returned the second time.

node-6# isi_dump_fabric int-a

Could not discover switch address.

node-6# isi_dump_fabric int-a

If you are using ethernet switch you should be able to ssh switch from isilon cli. You can check for knowledge base article at support site for same
