    how to create a topology file with the MSB7890 and 2 HCA card

    pengchengzhu

      Hello , Mellanox Academy support team

           I am on studying the Infiniband Fabric ,and I have problem on create the topology file on the MSB7890 and 2 HCA card connect to it ,but I don't know how to create the topology file here ,some question here are :

      1: the course on the topology file is out of date and not clear to me ,it is focus on the SX6036/SX6025

      2: no ibnl file related tothe MSB7890 switch,

      3: no SM defined in the topology file

       

      here is what I do in my topology file :

       

      [root@node01 ~]# ibdmchk -t a.topo

      -------------------------------------------------

      IBDMCHK Cluster Design Mode:

      Topology File .. a.topo

      SM Node ........

      SM Port ........ 4294967295

      LMC ............ 0

      -I- Parsing topology definition:a.topo

      -W- Ignoring 'p13 -> HCA-1 node01 p1' (line:2)

      -W- Ignoring 'p17 -> HCA-1 node04 p1' (line:3)

      -I- Defined 1/2 systems/nodes

      -E- Fail to find SM node:

      [root@node01 ~]# cat a.topo

      MSB7700 MSB7700

      p13 -> HCA-1 node01 p1

      p17 -> HCA-1 node04 p1

       

       

      here is the link for my ib network :
