Why is my RAID controller in a foreign state?
The loveliest error in the world. When I went into the RAID configuration it showed no virtual disks but under the Foreign View it shows all 3 disks, 2 of which are online. The other is in a rebuild state. Any ideas?? Does the PERC allow you to import the foreign drives? The PERC believes that the drives are from another system.

Per dell server administrator a drive had a ‘foreign’ state. Not sure if the drive was bad or not, we got a used replacement drive, hot-swapped it and it also has a ‘foreign’ state. How can I erase the foreign state and have it rebuild the raid 1?
What kind of RAID controller does Dell R320 have?
I have a Dell R320 that has two physical drives in a RAID1 array. The RAID controller is a PERC H310 Mini. During routine maintenance I discovered that one of them was showing as faulty. I had to reboot the server and now the previously fault one is showing as foreign (but not faulty).
Is the PERC H310 mini RAID controller faulty?
The RAID controller is a PERC H310 Mini. During routine maintenance I discovered that one of them was showing as faulty. I had to reboot the server and now the previously fault one is showing as foreign (but not faulty). I will be replacing the drive regardless, but I’m unsure as to what to do once I physically replace the drive that has failed.
