Answer

  • Estimated time depends on if the firmware is upgraded Offline (Parallel) or Online.
  • Timing of the drive firmware download operation:
    • The parallel drive firmware download operation can take as long as 90 seconds to complete if all drives are updated on a 24-drive system. On a larger system, the execution time is slightly longer.
    •  The online drive firmware download operation will take approximately two minutes per drive to complete. Actual time depends on several factors, including the following:
      •  I/O load on the storage array and the amount of I/O activity occurring during an online firmware download operation (write-heavy workloads will cause the online firmware download time to increase)
      • Number of drives that are participating in the download
      • Drive performance
      • Number of volumes and size of volumes that reside on the drives that are participating in the download
      • RAID level of the associated disk pool or volume group

Notes:

  • SSD Cache drives must be offline and suspended to complete the upgrade.
  • The start and complete time of Online Drive Firmware Upgrade (ODFU) can be confirmed by the following event from MAJOR-EVENT-LOG:
    • Start time
