Installing larger drives for existing mirrored array
We've got a PE 1800 with a CERC 6 channel controller. Drives 0 and 1 are 40 gig, mirrored, and contain the OS on a 12 gig partition and website on the remaining partition. The remaining four channels have 500s in a RAID 5 configuration. It's quite a few years old and after installing programs over time (especially SEP 11) the C partition is nearly full. I'd like to replace the 40 gig drives with some 80+ drives.
My first idea is to pull one drive, put in the new 80 gig and let it rebuild the array. Do the same thing for the second new drive. Once the new drives are workig in the new array use Partition Magic to expand the partitions.
Is this a reasonable way to do it or should I try something different? I'll certainly Ghost the whole drive to an external before attempting.
Thanks,
Mike

Well... it failed miserably. Put the two original drives back in and left that pig alone. I guess I'll have put in the newer hard drive, format it, partition it, and then attempt to use Ghost to copy the partitions. Problem being Ghost is Symantec and they make everything more difficult to use than is necessary.
Any alternatives to Ghost (not that anyone is reading this...)

I found that one as well but after getting squat from this board I put in a support ticket and got the easy answer from Dell.
1. Put the first larger drive in. Let it rebuild.
2. Put the second larger drive in. Let it rebuild.
3. Reconfigure the array which will reconfigure the array so that it will span the entire 160 gig drives instead of the 40 currently allocated and a fecesload of extra space not available to the same array.
4. Delete d: partition.
5. Use expart.exe to expand the c: partition into the newly available free space.
6. Create the d: partition using Disk Manager and restore the data from backup.
