System: Power Egde R420, Perc H710, 4x 1TB Sata disk,
There was a raid 5 with 4 disk. 1 disk is displayed as foreign (online).
In the disk utility, i cleared the foreign configuration. the mentioned disk show 2 green LED. After a while the disk blinks orange, and then it shut off.
Physical disk shows me just the other 3 disk.
When I reboot the system, all disk are again there, but the one who was foreign is displayed foreign (online) again.
What can I do to reset the disk, so that I can create a Raid 5 with 4 disk?????
Please help
