Tom,
First Question. Some of the older Compaq RAID Controllers didn't allow raid expansion, but all of the new models (52xx, 5i, 64xx, 6i) should allow this. Check the firmware levels on the card, and also check the version of the PSP (ProLiant Support Pack) your running on the server. From within Windows, you should be able to expand the array no problems. There will be performance hit while it does it (since its shuffling data around), but the machine should be reasonably happy.
Second Question. You *might* be able to extended the C: partition, but the requirements outlined in the Microsoft Support Article: http://support.microsoft.com/default.aspx?scid=kb;en-us;325590, are fairly stringent:
- For Basic volumes, the unallocated space for the extension must be the next contiguous space on the same disk (this wouldnt be do-able, unless you deleted the second partition before attempting the resize).
- Only the extension of data volumes is supported. System or boot volumes may be blocked from being extended. (well, seeing as your trying to extend the C: drive, this could be a problem)
Last Question, A Single Channel (scsi bus) within a controller can have any number of arrays consisting anywhere from a single drive, up to a full bus. Its purely a logical distinction.

Hi, I have a server with a 70gig raid 5 array(3 physical drives). Is there any way to add more drives to extend the array to more length. Like adding a 30gig drive to the existing raid array and making a 100gig c: drive or is this impossible. everytime I add a new drive to the controller, compaq sees 2 arrays- arrayA being the 70gig(3 drives) and arrayB being the new drive. It doesn't give me an option of adding the 30gig drive to arrayA. so i have 2 paritions in widows- a 70gig c: volume and a 30 gig E: volume. so, i have 2 questions-\is it not possible on the hardware level to add a new drive to an already existing array?
and, is there any way to extend the c: partition?(this is win2k and i assume its not because the drive was originally a basic disk, but i just want to make sure). i assume if you format any drive as basic and later upgrade to dynamic, extending a non-contigious volume won't work...
Ok, i have one more question as well :)- when a raid controller shows 2 arrays, does that mean the drives are on 2 diff scsi channels or is that just a logical distinction..
Thanks alot. sorry for the OT, i know this isn't a compaq list... List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/
