Checking the system's condition before upgrading software

Before upgrading a StorageGRID system, you must verify the system is ready to accommodate the upgrade. You must ensure that the system is running normally and that all grid nodes are operational.

Procedure

  1. Sign in to the Grid Manager using a supported browser.
  2. Check for and resolve any active alarms or alerts (preview in StorageGRID 11.3).
    For information about specific alarms or alerts, see the monitoring and troubleshooting instructions.
  3. Confirm that no conflicting grid tasks are active or pending.
    1. Select Support. Then, in the Tools section of the menu, select Grid Topology.
    2. Select site > primary Admin Node > CMN > Grid Tasks > Configuration.

      Information lifecycle management evaluation (ILME) tasks are the only grid tasks that can run concurrently with the software upgrade.

    3. If any other grid tasks are active or pending, wait for them to finish or release their lock.
      Note: Contact technical support if a task does not finish or release its lock.
  4. Refer to the lists of internal and external ports in the 11.4 version of the installation instructions for your platform, and ensure that all required ports are opened before you upgrade.

    Specifically, you must ensure that this port is not blocked between sites or nodes:

    • 18019: Used for internal traffic between Storage Nodes related to the Chunk service (used for erasure coding)
    Attention: If you have opened any custom firewall ports, you are notified during the upgrade precheck. You must contact technical support before proceeding with the upgrade.
  5. If you configured an SNMP agent for StorageGRID 11.3, confirm that your definition for community_strings is correct.
    There are no longer separate fields for IPv4 and IPv6, and only five strings are now supported. Each string must be 32 characters or less.
    Attention: A StorageGRID 11.4 upgrade precheck will fail if your existing community strings are too long.
