ProcedureHow to Upgrade Host Adapter Firmware

Upgrade your host adapter firmware if you want to apply bug fixes or enable new functionality.

Before You Begin

This procedure relies on the following prerequisites and assumptions.

  1. Determine the resource groups and device groups that are running on the node on which you plan to upgrade the host adapter firmware.

    # scstat
  2. Move all resource groups and device groups off Node A.

    # scswitch -S -h from-node
  3. Perform the firmware upgrade.

    For the procedure about how to upgrade your host adapter firmware, see the patch documentation.

  4. (Optional) Return the resource groups and device groups to Node B.

    # scswitch -z -g resource-group -h nodename
    # scswitch -z -D device-group -h nodename
