Preparing to update individual nodes

Before you update nodes individually, ensure that the system is ready for the update.

Verify the prerequisites: Updating the system manually

After you verify that the prerequisites for a manual update are met, follow these steps:

  1. Use the management GUI to display the nodes in the system and record this information.
    For all the nodes in the system, verify the following information:
    • Confirm that both canisters are online.
    • Identify which canister is acting as the configuration node.
    • Record the service IP address for each canister.
  2. If you are using the management GUI, view External Storage to ensure that everything is online and also verify that internal storage is present.
  3. If you are using the command-line interface, submit this command for each storage system:
    lscontroller controller_name_or_controller_id
    where controller_name_or_controller_id is the name or ID of the storage system. Confirm that each storage system has degraded=no status.
  4. Verify that all hosts have all paths available to all the volumes that are presented to them by the system.
    Ensure that the multipathing driver is fully redundant, with every path available and online.
  5. If you did not do so previously, download the installation package for the level that you want to install. You can download the most current package from the following website:
