Virtual Disk array configuration lost after a reboot
Hi,
I have the biggest issue right now. I have a PowerEdge Sever with 3 MD1200 direct attached storage. The MD1200 are connected via H800 Perc controller.
I remotely rebooted the server this morning and it got stuck during the boot process. I can by the office only to see the screen shows that a drive was removed. I power cycled it and hit any key to continue. To my surprise, the bios did not see any drives on the Perc H800. it did see the virtual drive that were configured on the H710P controller which houses my boot OS.
When I went to the raid management. it has a failed disk. I have it set to raid 10 so I was under the impression that it will still work regardless of a failed disk.
I'm now in a dilemma on whether to rebuild the array without initializing the disk. The MD1200 houses multiple DB's for my SQL. I do not want to loose any data. I have a full backup yesterday but I'd rather not loose any data on the disk.
My question is why did it loose the array configuration? How can I rebuild back the VD array without erasing any data on the drives.
Anybody here that had the same issue, please point me to the right direction.

Hello Lainezki,
Have you tried to reboot your MD1200 stack? Was there any updates that were applied recently? When you go into the PERC H800 bios what is it displaying?
Please let us know if you have any other questions.

Hello,
I have the same problem with md1200. I am also looking for a solution to recover the configuration of virtual drives without losing any data. But I do not see such a possibility even though the della page is written using openmanage. There is no option to import a foreign configuration. Please help.

Hello Sait0,
If you go in to the PERC BIOS, & you look under disk management what is listed? Were there any updates done to your PERC card or your MD1200 prior to it not being seen?
Please let us know if you have any other questions.

We too have lost our RAID controller configuration after performing a system reboot of our PowerEdge 2950.
We didn't not perform any update and our RAID management controller is PERC 6/i.
On BIOS here is what it shows under PD Mgmt:
Drive ID Vendor Size/MB Type State DG
--:00:00 ATA 953344 SATA Foreign
--:00:01 ATA 953344 SATA Foreign
--:00:02 ATA 953344 SATA Foreign
--:00:03 ATA 953344 SATA Ready
--:00:04 ATA 953344 SATA Foreign
At this point, is it safe to import Foreign Config in BIOS under VD Mgmt ?

Hello support_gestion-ressources,
Your PERC6/I is for your internal drives and not for your MD1200. Your MD1200 should connect to a PERC 6/e.
What you want to do is to import the configuration. Once the import is completed then you should be able to exit VD management and let the server boot.
Please let us know if you have any other questions.

Hello,
Thank you for your quick response.
In fact, it concerns our PERC6/I RAID Controller for our internal drives since we do not have an MD1200.
We did import foreign configuration but there was an error message saying that 3 import failed (out of our 6 internal disks) with the following error code 0x54.

Hello support_gestion-ressources,
What is the current version of firmware for your PERC 6/i? Do you have a backup of your data that was on your VD? If you don’t have a tested backup of the data then I would contact a software recovery company to see if they can recover the data. You can also try to do a retag on the VD. Now if you try to do a retag but doing a retag can cause data loss in some cases.
Please let us know if you have any other questions.

You can get back your lost array configuration and even get the data recovered from those drives using a tool named Stellar Data Recovery Technician as this tool rebuilds the virtual RAID to recover data from failed, broken or corrupt RAID arrays. You can get your problem fixed using this tool and can also recover any kind of lost data. Try free trial of this software to reconstruct the RAID and get a preview of recoverable data.
