Use the following procedure to replace a Myrinet system interconnect board, InfiniBand system interconnect board, or a Quadrics system interconnect board in an CP6000 system. The example commands in the procedure use node n3.
Log in as superuser on the head node.
Ensure that no applications are running on the node with the faulty system interconnect board:
# scontrol update NodeName=n3 State=DRAINING \
Reason="Removing node" |
Use the stopsys command to shut down the node (on which the card is to be replaced) in an orderly way:
If the faulty system interconnect board is on the head node, shut down the node with the shutdown command:
Remove the old system interconnect board.
Install the new system interconnect board.
Invoke the startsys command to turn on the node's power:
# startsys --image_and_boot n3 |
“Using the System Interconnect Diagnostic Tools” describes diagnostic tools for the Myrinet, InfiniBand, and Quadrics system interconnects.
