Pre-Upgrade Health Check Utility

Hypercheck: Pre-Upgrade Check Tool

Cisco recommends running Hypercheck health check tool before the upgrade to validate all upgrade requirements are met. The Hypercheck: HyperFlex and Pre-Upgrade Check Tool are automated health and pre-upgrade checks that are designed to ensure your clusters are healthy before you upgrade. It is imperative that this health check is not just performed, but that you take corrective action on any cluster that is found to be unhealthy. Correct all issues reported by the Hypercheck health check before continuing with the upgrade.

If you prefer not to run the Hypercheck tool, please refer to manual checklist in chapter 14. These checks are not as comprehensive as Hypercheck so manual validation is not recommended.

Hypercheck Pre-Upgrade Utility for Cisco HX Release 4.5 and Later

The HyperCheck 4.5 script is included with the product and Rest APIs integration has improved performance. When a cluster is deployed, Hypercheck is included as part of the cluster. New features and checks include: Cluster Information table, DR (local and remote network) and SED checks for users who have them enabled.

Procedure

Step 1

Run the hypercheck command to start the checks.

Step 2

Once check is complete, verify results. If there are failures, perform the steps for any given workaround solutions, confirm the cluster storage capacity, and check settings. For more settings details see, Preparing for Upgrade.
