T430 issues with PERC H710P Secondary Array RAID 5
Hoping someone can halp with this?
I ran into an issue over the weekend that has me stumped.
I have a Dell T430 with PERC H710PController, Array 1 is a RAID 6 with 5 ea 480GB SSD working fine, Array 2 is RAID 5 with 5 ea IBM 9VW066-039 ST9600105SS 600GB 10K SAS 6gbps drives and is degraded.
One of the SAS drives was reporting eminent failure so I purchased two new identical IBM drives.
As per Dell instructions I set the drive offline in the controller and replaced the drive.
The drive shows as ready but cannot seem to get it to recognize it as part of the existing Array.
When I tried to add another drive to make global hot spare it says the drive is unsupported and "blocked"
My seconday array is still down and I need to recover the Data and start over to rebuild the array.
Looking for suggestions to either fix the array with what I have or recover the data and start over.
Data was static and backed up but client misplaced mobile HD with last known good backup.
Any help appreciated
Thank you

Hello JMZ_NM
Was Array2 degraded before you pulled the predictive fail drive?
I'm asking this because you say you added another drive, after replacing the pred fail drive, and that the array is down.
You can lose one drive on a RAID5 and the array would be Degraded. If you lose two drives, like pulling a drive on an array that is already degraded, the array would be failed.
If this is the case you need to try to get the last drive, that failed back, into the array.
Shut down, install all the original drives of the array, power up and see if it automatically imports. If not go into the controller BIOS and see if there is a Foreign Configuration you can import.
What typically should happen is the array is optimal with a pred fail drive. You would offline the pred fail drive and remove it. Install the replacement and the rebuild should start automatically. If it does not then you set that drive to a hot spare and the rebuild should start.
If you are unable to get the array functional then you may need to consider sending all the original member drives of the array to a data recovery company.

Thanks Charles ... Yes the array was degraded prior to drive removal but when I replaced with a new exact same make/model/revision drive the controller siad it was blocked or unsupported. So...I removed the new drive and replaced it with the original drive in the same slot and it says foreign config ... I import foreign config and the drive says "ready" but no option to rebuild or add the drive back to the array

Hello JMZ_NM,
Thank you for the update. As you are aware if you have a RAID5 that is degraded and remove another drive then that would fail the array.
Are you confident you have all the original member drives of the RAID5 that were installed when it was in a degraded state?
You may try shut down, unseat all the RAID5 drives, don't have to completely remove the, Boot up into the controller BIOS to see the array is not present. Then shut down and reseat all the RAID5 drives you had in initially when it was degraded and boot into the controller to see if you can import.
You can take some images of what you see in the controller BIOS and post them.

Thanks Charles, Yes 100% sure as I marked the drive I removed as well the new ones.
I have a week long project I will be on staring this week and this client is 3 hours away so I will post pics and provide updates when I get out there again. Data is not 100% critical for operational purposes but definitely need to recover it at some point.
Thanks thus far ... appreciated !
