  1. Download the firmware from the Sun Download Ceneter (SDLC).

  2. Obtain the LIDs from the fabric for the Infiniscale-IV devices.


    # ibswitches
Switch  : 0x002128183ea40050 ports 36 "Sun Blade 6048 InfiniBand QDR Switched NEM I4B" base port 0 lid 4 lmc 0 
Switch  : 0x002128183ea40040 ports 36 "Sun Blade 6048 InfiniBand QDR Switched NEM I4A" base port 0 lid 3 lmc 0

    Example shows that I4B’s LID is 4 and I4A’s LID is 3.

  3. Use flint tool to update the switch firmware on both switches.


    # flint -d lid-3 -i ./QNEM-04-I4A-1.9.BIN b

  4. Reset the switches.

    If the node board is installed in the shelf slots 0-5, reset the I4B switch before resetting the I4A switch. If the node board is installed in the shelf slots 6-11, reset the I4A switch before resetting the I4B switch. Ensure that the reset completes before resetting the other switch. A switch reset could take up to 90 seconds to complete.
