Playing musical chairs with RAID configuration
I currently have a Proliant 1200 with a SMART-2SL RAID controller. There
is one drive installed in the system, naturally configured as RAID 0. What I'd like to do now is have 2 drives in the system and configured as RAID 1. I also have a 7000 with an empty drive bay, so I figured what I'd do is: 1) Put a blank pair of drives into the 7000 and set them up as a RAID 1 array; 2) Take the drive from the 1200, and put it into the 7000 as a RAID 0 array; 3) On the 7000, do a dd from the RAID 0 drive to the RAID 1 drive; 4) Take the pair of RAID 1 drives out of the 7000 and put them into the 1200; 5) Delete the RAID 0 array from the 1200 and set the drives up as a RAID 1 instead. Now question is: I've noticed that when you delete an array configuration from the server, it takes the drives out with it. How do I change the array type without nuking the drives? |

why go to all that trouble?
why not just put 2 drives in the 1200, configure as RAID1, and install your OS ? Seems pretty convoluted what you are suggesting, unless i'm missing something. - LC "." wrote in message om.au...

It's been a while since I've messed with 2sl's, but I think that you
can simply expand the arrary and make it a mirror, rather than jumping through your hoops. I am certain you can do it with later S/A's, but it seems like a pretty basic feature. Basically, you have to install the 2nd drive into the 1200, run ACU from either the f10 partition or a smartstart cd, and change the raid level on the existing array. Now, depending on your version of ACU / SmartStart, this process can differ slightly, but it is either going to involve expanding the array and making it raid 1, or simply migrating it raid 0, but like I said, I think you can do this without the 7000's help.
