Important Information
This update will not run if any of the following conditions exist
1. Any Virtual Disk that is not optimal.
2. A RAID container that is performing a Background Initialization or Consistency Check.
3. A Rebuild, Resync, or copyback function is taking place.
4. A RAID set that is Partially Degraded or in a Degraded state.
This update will run on drives remaining in a RAID set that is in a Offline state.
There is an architectural constraint with Dell DUP HDD firmware update utility, related to system memory utilization, which is typically encountered on systems with minimal system memory, memory-intensive configurations, multiple RAID controllers, or memory-intensive applications. This issue is typically reported as - The operation was not successful because the device buffer write has failed. And will result in an aborted attempt to update firmware on the identified HDD. Error codes associated with this failure mode include 8009 and 8017. Once an error is detected, the update session is aborted. There is no data integrity or data availability risk associated with this issue. Subsequent attempts to update the HDD firmware may succeed, particularly if system resources are freed up.
