An administrator is preparing to upgrade a PowerFlex cluster. What steps should they follow to ensure success?

Question

Options

• ABackup the current cluster configuration
• BValidate hardware compatibility for all nodes
• CEnable deduplication for all volumes
• DVerify the cluster health status in PowerFlex Manager

• A
  81% (30)
• B
  5% (2)
• C
  14% (5)

Explanation

Before upgrading a PowerFlex cluster, backing up the current cluster configuration (A) protects against data loss or misconfiguration if the upgrade fails, while verifying cluster health status in PowerFlex Manager (D) ensures there are no underlying issues that could cause the upgrade to fail or compound existing problems - both are standard pre-upgrade prerequisites in Dell PowerFlex best practices.

Hardware compatibility validation (B) is important when adding new nodes or planning a major version jump, but it's not a required pre-upgrade step for an existing, already-running cluster. Enabling deduplication (C) is a storage efficiency feature completely unrelated to upgrade readiness and could actually introduce unnecessary risk by changing volume settings right before an upgrade.

Memory tip: Think "Back up, then Check up" - always Back up config and Check cluster health (via PowerFlex Manager) before any upgrade. If the system isn't healthy going in, it won't be healthy coming out.
