Applies to

  • E-series
  • I/O Module (IOM) firmware

Answer

  • Yes, the storage system automatically downgrades a replacement IOM if it has a newer firmware version.
  • Conversely, if the replacement IOM has an older firmware version, the system automatically upgrades it.
  • This ensures that a spare IOM can be used in any system regardless of its firmware revision.
