It seems there is only an option for:
Raid 1+0 Raid 0
I got two Disk, and wish to do a mirror. What are the options for me? Thanks.
You can't by definition have a RAID 1+0 disk array with only two disks. Create an array as RAID 1+0 with two disks you will have a RAID 1 array.
According to the manual, http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c00729544/c00729544.pdf , if you're in the BIOS ROM utility ("ORCA"), they term a RAID-1 (mirror) as a "RAID 1+0". Select the controller, press F8, select the drives and RAID level, confirm, and exit the utility.
If firmware version HP Smart Array P420i Controller is older then 3.04, only RAID 1+0 is available and should be used
The p410i supports for sure raid 1.
Are you trying with the bios utility or smart start?
