Which conditions must be met to begin a PowerFlex upgrade? (Choose two)

Question

Options

• AAll nodes must be online
• BCluster health status must be green
• CAll fault sets must be reconfigured
• DMetadata Managers must be active

• A
  6% (2)
• B
  84% (26)
• C
  10% (3)

Explanation

Before a PowerFlex upgrade can begin, the cluster health status must be green (B) - this ensures no pre-existing faults would be compounded during the upgrade process, which involves rolling node restarts. Metadata Managers must be active (D) because they coordinate data placement and protection; if they're unavailable, the cluster cannot safely manage the data redistribution that occurs during upgrades.

Why A is wrong: Not all nodes need to be online simultaneously - PowerFlex is designed for rolling upgrades, so the system intentionally takes nodes offline one at a time. Requiring all nodes online would actually conflict with how the upgrade works.

Why C is wrong: Fault sets do not need reconfiguration before an upgrade. They are a protection configuration that remains in place; reconfiguring them would be an unusual, disruptive pre-step with no basis in the upgrade prerequisites.

Memory tip: Think "Green light, Managers ready" - like a flight pre-check, you need a clear health signal (green status) and your air traffic controllers (Metadata Managers) active before you're cleared for takeoff.
