I have Server Poweredge R710 running windows Server 2012, we use Raid 6i on.
Today someone was removed and back the Disk 0 and then the system reboot but dont back again to work!
the Bios Display : No Boot device available
Strike F1 to retry boot, F2 to System Setup, F11 for BIOS boot manager.
I was try all option and check the boot sequence and it's okay, but when I got for Perc6 Management I found Disk 0 and Disk 2 as foreign (DisK 1 and Disk 3 are online).
please how to resolve this problem, the data in is important and I have no backup.
You list 2 physical disks as being in a foreign state. You should just need to import them. This can be done from the PERC configuration screen. You would just need to highlight the controller, press F2, select foreign operations, and import the foreign configuration.
I would recommend importing the drives and this is described in detail in the manual I mentioned. The import operation will attempt to bring the drives back as active members of the array by scanning the metadata on the hard drives. If it is successful, your data should be accessible. This is the safest way to attempt to bring this back online.
If you cannot import the foreign configuration from VD Mgmt, you would need to deploy a new virtual disk. You could try retagging, which would be deploying an identical virtual disk to the last one. However, before doing this, I would definitely verify any backup solutions, first.
Clearing the foreign config gets rid of the metadata that identifies the RAID information for a virtual disk. We'll need to attempt to re-write it with the retag. Provided you have a backup, you would need to create a RAID array of the same parameters as the one that went foreign. You want to not perform an initialization, as that would cause data loss. If you create the array with the same RAID level and stripe size, it should be ok.
Before proceeding, please double check your backup. If the backup does not look good, you'll want to look at using some sort of a data recovery service.
For example:
With the foreign configuration cleared, the virtual disk would now be deleted. Once it is deleted, you would then make a new one exactly the same as the last. Do not change the RAID level or stripe size from what the last was. Proceed through the wizard and choose not to initialize. This will hopefully make that data available to you.

Hello,

You can get the PERC 6i manual through there, page 89 goes into greater detail with foreign configurations.
