i have a HP ProLiant DL380e Gen8 Server with ah P420 Raid Controller. I have configured Raid 5 with 3 Disks. I want to expand the Raid with 2 more Disks. But i cannot access the Raid Controller -> HP Smart Storage Administrator anymore. On Bootup screen it says press F5. When i press F5 it recognize it but it stucks for 10 seconds and then boots to Ubuntu.
Does anyone have an idea why i cannot access it anymore?
