Switch – set the Ca name on unmanaged mellanox switch

infinibandmellanoxswitch

How can I set the Hostname/Description of a Mellanox/Infiniband unmanaged switch?

I would like a way to abstractly distinguish quickly which switches are which when doing 'ibswitches' or 'ibnetdiscover'.

For HCAs that are in Servers, the hostnames are set, which is great. Just need a solution for switches.

Example: (All of the switches come up as the following "SwitchX – Mellanox Technologies") 

[26]    "S-e41d2de300756550"[25]                # "SwitchX -  Mellanox Technologies" lid 6 4xFDR
[27]    "S-e41d2de30074bc40"[21]                # "SwitchX -  Mellanox Technologies" lid 5 4xFDR

This would be beneificial when looking for ibnetdiscover and being able to quickly find which HCA card goes into which switch….

vendid=0x2c9
devid=0x1011
sysimgguid=0xf45214d300514560
caguid=0xf452140300514560
Ca      1 "H-f45214d300514560"          # "mgmt2 HCA-2"
[1](f45214d300514560)   "S-e41d2dd3007551f0"[15]                # lid 11 lmc 0 "SwitchX -  Mellanox Technologies" lid 10 4xFDR

You can specify "--node-name-map FILE" for ibnetdiscover and configure the mapping between GUIDs and your desired names, so this name would be shown when running ibswitches/ibnetdiscover.

--node-name-map <node-name-map>
    Specify a node name map. The node name map file maps GUIDs to more
    user friendly names. See file format below.
