Changing drives on an NT server?

I un understand that you have a RAID configuration and want to change all the 5 drives ? The best thing would be to reinstall NT from scratch .Of course it will cost a lot of time . Usualy you can overcopy a lot of things from the old server (backpup) but this depends on what exactly do you have on it - application or file server or both ? I suppose you don't have a BDC also ? Anyway it will be a good experience and it's hard to get advices from the outside so you can save some points :) .
If you are not sure better consider an outside help.

Good luck !

Im guessing you want to change the drive letters on the server, if that is the case logon as an administrator and run ?Disk Administrator? under ?Administrative Tools (Common)? on the start menu, or the WINDISK.EXE. This will give you a graphical display of all the drives.

Then if you click on the drive, there is change drive letter, you can then pick any inactive drive letter, as long as you don?t have anything else open you can change the drive letters with a click, the only drive letter you should NOT change is the partition where NT is install general one of the first two drives. If you do so, it will ask you to reboot and tell you, you need to edit the BOOT.INI file, if you go down this path make sure you take not of the change to partition number it tells you.

Now if you only want to change the drive letters on the clients, either edit the logon script, found under winnt\system32\repl\import\scripts or just disconnect your mapped network drive and reconnect them as you want.

Good luck, and have a great christmas

Are the drives "Hot Swapable" ? This was an option on the 1600's.
Do you have hardware raid 5 ?
Does one of the drives have the OS and the others belong to the array ?
What you lack in experience can be overcome by obtaining information.
If you don't know how to get the answers to these questions, email directly and I can walk you through it.
I've got 4 of the 1600s with different configs on each.

Hope I'm not too late to help (Merry Xmas btw). I am presuming you have a raid 5 setup, and presumably hardware based.

Make sure to have good backups of your system before the change (of course). This includes a backup of your raid configuration(most raid cards come with a backup to floppy routine). Then, create a second raid 5 set with the new drives(you don't even have to take the first raid set down, unless you don't have the physical space). Install WinNT on it, and make sure you do a new installation on the new set, and not accidentally install/upgrade over the original. Make sure your configuration is exactly like that of the original set. Then restore the data to the new installation from your backups. Then test to make sure yournew set is working as expected.

The sweet thing about this is you do not have to remove your (if you have the space) original raid set until you get the replacement working. I've done something similar and the only problem I ran into was some pointers im my application to specific drive letters (as I had the original and new raid set in simultaneously).

Hope that helps and good luck.
