SOLVED Failed perc damaged multiple disks, how to fix?

[Daisuke]

I had a H710 perc that failed in my Dell R720xd. I replaced it with a new one and when I started Scale, the polls were ruined with several platter disks showing as faulted or degraded. Since this is a new setup, there was no data into pools, so I decided to destroy all pools and start over. Re-creating the pool was difficult, I had to wipe each of 12 disks. Once all disks wiped, the pool was created but the disks show the same status, faulty or degraded.

What should I do next, to fix this issue? Is there a command I can run in a Linux livecd to re-format the disks properly? Everything is a mess. I also have 2 SSDs installed that it takes forever to create an applications pool in mirror.

Code:

# zpool status default
  pool: default
 state: DEGRADED
status: One or more devices are faulted in response to persistent errors.
    Sufficient replicas exist for the pool to continue functioning in a
    degraded state.
action: Replace the faulted device, or use 'zpool clear' to mark the device
    repaired.

I get tons of errors like:

Are you sure the replacement PERC is in IT mode? It's possible your replacement PERC is also bad.

 

[Daisuke]

Yes, I flashed the perc to IT mode successfully. If the perc would be defective, I would not see the disks, prior making the pool. When the first perc failed, a big red X was showing next to each pool. Before destroying the pool with new perc installed, it was showing several disks online:

Code:

# zpool status -v default

    Sufficient replicas exist for the pool to continue functioning in a

It has be a way to destroy the pool and wipe the disks properly, I don't think the UI is the right choice in my situation.

 

[Samuel Tai]

Try reseating the replacement PERC, and cleaning the contacts with alcohol.

 

[Daisuke]

The alcohol did something, no more issues! The perc was seated properly, I'm familiar with how delicate they are.

Next time try blowing hard on it from an angle... oh wait, PERC isn't a Nintendo game cartridge. :)

@anodos, I take it you've seen Nick Robinson's epic Blastoise resurrection video?
