I have 5 ProLiant ML350 Gen8s. Four of them are in service running Raid-5 with three 450gb SAS drives. The last one will not let me configure Raid-5. It seems to only allow Raid-0. The only difference that I know of is that server is using three 600gb sas drives. All five servers have an embedded P420i controller. Any ideas how I can get Raid-5 running on this machine.
