RAID 1 + 0

zigity — Sat, 11 Feb 2006 11:48:20 GMT

Can someone give me the CLI command to set this up. I know how to create Raid 1 or Raid 0, but how do you use both?

I have a MSA1000 with 14 drives and want to mirror the two bays and stripe across. Thanks for your help.

If more than one pair of drives are included in a RAID 1 array, the array is going to RAID 1+0 automatically.

It's Just one chassis with 14 drives. What is the best way to set this up?

If you want to add all this disks in one RAID1+0 do this:
ADD UNIT 0 DATA="DISK101-DISK114" RAID_LEVEL=1

I still don't understand how the Raid 0 fits in this. How does it do it automatically?

Thanks for the help.
