Why is Raid 5 not Available

Shawn McConnell! — Fri, 23 Jan 2009 20:00:49 GMT

I'm using SmartStart 8.00. The server is a proliant DL360 G5 with four 146GB drives.

I created the array and then when I go to create the logical drives it is only showing me RAID 0 and RAID 0+1.

So I checked some notes and found out that for RAID 5 you need a minimum of three disks. So what am I missing here ?

I have another server same model with 5 146GB drives and I set that one up RAID 5 with one spare.

Any thoughts ?

Are you able to see all the 4 drive in configuration? Looks like server is only able to see two drives. Please check if drive LEDs are lighting up properly.

From the DL360 G5 quickspecs:
http://h18004.www1.hp.com/products/quickspecs/12476_div/12476_div.html

Entry Models: HP Smart Array E200i/64MB Controller (RAID 0/1/1+0) (128MB BBWC optional)

From the Smart Array E200 quickspecks:
http://h18000.www1.hp.com/products/quickspecs/12460_div/12460_div.html

NOTE: The 128MB BBWC upgrade is required to enable RAID 5 support on the Smart Array E200i.

The controller is an E200i. So that looks like the answer. Thanks.
