Power On a Fabric Card

In this procedure, you issue commands to both the CMC and the Linux InfiniBand host.

1. Identify the prerequisite and subsequent tasks you must perform in conjunction with this procedure, to achieve a goal.

   See the table in Servicing the Fabric Cards and Fabric Card Fillers.

2. On the CMC, enable the fabric card using the enablestby command.

   For example, to enable fabric card 0:

   # enablestby fc 0
   fc 0 is now enabled
   #

3. If your InfiniBand fabric uses the fat-tree algorithm, you must update the root GUID file with the new GUIDs.

   Otherwise, go to Step 4.

   1. Type the following command on the CMC to retrieve the fabric card base GUID:

      # getbaseguid fc slot

      where slot is the number of the fabric card you installed. For example:

      # getbaseguid fc 0
      Base GUID = 0x00bad0fc0009f000
      #

   2. For the GUID, add the following values to make two new sums:

      • 0xa2

      • 0xb2

      ---

      Note - For a GUID that ends with two zeros (00), you are effectively replacing the zeros with a2 and b2.

      ---

      For example, 0x00bad0fc0009f000 becomes:

      • 0x00bad0fc0009f0a2

      • 0x00bad0fc0009f0b2

   3. On the Linux InfiniBand host, use a text editor to add these two new entries to the /etc/opensm/guid.txt file.
   4. Restart the Subnet Manager on the Linux InfiniBand host:

      # /etc/init.d/opensmd stop
      Stopping IB Subnet Manager..-.                             [  OK  ]
      # /etc/init.d/opensmd start
      Starting IB Subnet Manager.                                [  OK  ]
      #

4. On the CMC, power on the fabric card with the activate command.

   For example, to power on fabric card 0:

   # activate fc 0
   #

5. If necessary, upgrade the firmware inside of the fabric card and fabric card filler:

   See Upgrading the Firmware.

6. (Optional) Display and record the fabric card FRU ID information:

   # clia fruinfo IPMB_address 0

   where IPMB_address is from Component Addressing.

   The following example is the output for fabric card 0:

   # clia fruinfo 94 0 
   Pigeon Point Shelf Manager Command Line Interpreter
   94: FRU # 0, FRU Info
   Common Header:    Format Version = 1

        Version     = 1
