RAID 1 rebuild on P300 - what is the "Recovery" option in machine BIOS ?

2021-04-02, 15:43 PM

I have a ThinkStation S10 and the on-board RAID apparently works slightly differently than the P300.

On my machine I get the  "Press CTRL-I .." prompt to enter raid config.

 

On my friend's P300 there is no  CTRL-I prompt and RAID functions are accessible on the  "ADVANCED" section of the main BIOS.

This seems weird...but ok...

 

His machine has 2 x 2TB standard SATA drives and WAS set up for RAID1.

The drives are physically connected to SATA 0 and SATA 1 on the motherboard.

One drive started failing ... 

The drive on SATA 0 seems to be the sick one - Event Viewer posts bad-block events to "DR0" and the drive makes the funny re-calibrate noises from time to time.

 

My friend was messing around with it ...

swapped drive positions, disabled and re-enabled ports... stuff he should not have been doing ...

 

and it seems like he apparently destroyed the RAID config.

The machine is still running and bootable but no longer reports that it is RAID 1.

From the OS we see this:

 

 

 

Interestingly LSS shows a RAID exists???:

 

From F1 --> machine BIOS--> Advanced it shows no RAID:

 

 

 

If I go to the create RAID page I see this:

 

 

I can not find mention of the "Recovery" option in the manual.... 

 

Long story short:  Does anyone have any suggestions on the best way out of this mess?

 

I do have a current image of the entire drive that I made with Macrium s/w.

 

THANKS!

Jim

You should be able to rebuilt a RAID 1 a lot easier than a RAID0.  From your screenshots, it appears that the RAID array has been deleted.  The reason why you could still likely boot to the single drive (without RAID setup) is because the metadata is still there on the drive(s).  You might could recreate the RAID 1 array from within the BIOS oprom for the Intel SATA controller and be luckily enough that it still boots.

Thank you  mebsterbball   

 

yes I think my buddy somehow deleted the array config. when he was messing around.

One drive is going bad, and I have a replacement.

 

So when I have a safe interval to work in I will:

Remove the bad drive

install the new drive

Access the RAID Oprom in BIOS and create a RAID1 config. reboot and then see what happens  :-)

 

I'm not sure what  "Recovery" actually does, but since there is not a valid RAID config. stored,

I expect it would not do anything good for me.

 

I'll post back with the results, it may be a while this it a tax-accounting server ... and this is tax season  :-/
