Best Practice for replacing Poweredge 440SC drives in raid 1, SBS 2003R2, using Acronis Trueimage

Dell PowerEdge 440SC, SBS 2003 R2 with a Dell SAS5IR(a) raid controller, 2 drives in Raid 1 configuration.

I want to replace the above server's hard drives with larger drives and use using a Acronis True Image for Small Business Server boot CD to restore a previous backup image. Once the 2 new drives are installed, will I need to use the Dell raid manager at boot to remove the old array and or create a new array with the new drives, or can I simply boot from the Acronis rescue CD and restore my image without using the raid manager at the initial boot? If I need to use the raid manager at boot, it appears that Ctrl C will allow me to access the raid configuration utility.

Thanks,
Brad

Array information is stored on the actual disks and not on the controller, so if you replace the disks, the array info will be gone.
Once you replace the disks, you will need to create a new RAID 1 array with the Dell  RAID Manager and then once setup, you can put the image back and off you go.

alanhardisty,

I appreciate your response. Your answer may very well be correct. However, if the raid array information is stored on the disks and I have a Trueimage image file of those disks, why wouldn't the array information already be contained within the image file that I want to restore to the new drives? Is it not possible that Trueimage will restore the array information along with the rest of the data to the new drives?

Thanks,
Brad

I don't know the exact technical details for where the RAID info is stored on the disks, but it is not stored on the Data areas of the disks that you would be backing up, so you will be fine backing up the data areas and restoring as you will not be overwriting the RAID info as this is stored elsewhere.
I am digging for a more conclusive answer for you and will post one as soon as I find it.

Can't find anything on this anywhere without calling someone like Adaptec for their chief boffin!  You will just have to take my word for it at this stage I'm afraid, which is hopefully good enough - been doing IT for 20 years and have lots of happy customers ;-)
