It’s not unusual to get a “History Of Failure” warning sign in your Dell EqualLogic PS Series storage array.
Dell EqualLogic storage arrays are a great option for small businesses because they’re affordable and easy to use. But like all storage arrays, they’re not immune to problems.
History Of Failure message appears when the disk failed before. Usually, the solution is to click on History of Failure and agree to keep using the drive. You may also need to update the array’s firmware.
But if you see this message too often, it’s time to replace the disk. Dell EqualLogic doesn’t support hot-swapping, so you’ll have to schedule some downtime.
You may check your disks on the health status of the disk:
Up status: Online, Spare
Warning status: Alt-Sig, History Of Failures, Replacement
Down status: Encrypted, Failed, Not Approved, Offline, Preempt Failed, Too Small, Unhealthy, Unsupported Version
To avoid data loss from a History of Failure warning, you must monitor the disks on your array, checking for any issues, and update your Dell EqualLogic firmware regularly. New versions often include fixes for known issues, including those that can cause data loss.
Making the disk with a history of failure as your spare disk is a quick solution. It prevents complete disk failure and consequent data loss. Then you can replace the disk later. Only remember that the new disk must have the same size as the others on the array in order to work properly.
Step 1. Download the latest Dell EqualLogic RAID firmware from the Dell support website. If you don’t have an account yet, you’ll have to create an account to access the firmware update kit.
Step 2. Decompress the file and run it.
Step 3. Follow the instructions in the wizard to update your Dell EqualLogic RAID firmware.
