DL360 G5 Mirror to Raid5 Config

Steve Twiss — Mon, 18 Aug 2008 12:25:58 GMT

Hi guys

I have a DL360 G5 with a 2 drives that are mirrored. I want to add a further drive to make this a Raid 5 array. Is this possible and can you forsee any problems. I can't afford to lose the data off these drives and im hoping to be able to break the mirror then create the raid array. Thanks

Hi Steve,

in theory, you will not lose data, however it is recommended to make a backup.

The controllers (bothE200i and p400i) require Battery Backed Write Cache(BBWC) option to make raid level migration. So if you have the BBWC :

1. Add the drive & go into Array Configuration utility
2. Expand the array & extend the logical drive
3. Click on the logical drive and click migrate array

Step by step on page 36:

Got ACU installed. On Page 36 point 4 it mentions possible raid levels. 5 is not listed for me as the array only has 2 drives currently and cant see how i add the new drive to this array? Thanks
