Dell PERC 6i RAID 5 and Two Foreign Disks
Posted on 2014-07-31
On a Dell PowerEdge server with a PERC 6i SAS RAID v 6.2.0 controller and RAID 5 configured with three drives, two of the three drives say Foreign when viewing the bootup/BIOS level raid configuration utility. Since two of the three drives are in the Foreign state the system will not boot and the Dell OMSA util cannot be run. The two drives listed as Foreign are flashing green and appear to be okay. How does one get the drives to become part of the existing RAID 5 array and configuration again while preserving the existing configuration (and data, OS, etc...) ?
