I need to change one hard disk with another one.
I have a raid 5 and i use hp array utility.
My disk is perfectly OK. I can do it offline, so no problem with turning off the server.
I want to fail the disk and replace it with another one(larger capacity). I know this will not increase my capacity, but i just need to do this for now.

What should i exactly do:
Turn off the server.
Remove the disk.
Replace the disk
Start the server.

Please this is a backup DC, and i haven't done this before, so i just want to make sure.
Should i do anything in the array utility, no hotspare is configured.

Raid 5 Array - are they newer compaq/hp disks (black with a purple catch?) if so push the catch lift the handle - slide the drive out an inch - wait 20 seconds for the drive to stop spinning - remove and replace the drive

ALL with the Server running :)  you can watch the drive rebuild in the ACU (the windows one) if you like

As you are already ware (I think) it will only rebuild to the size of the old disk :) ie if the old on was 18.2Gb and the new one is 72Gb then the "Raid portion" on the drive after it rebuilds will be 18.2Gb

Yes all you said is true.

One more thing: the "new disk" is actually placed in another server, it shows as unassigned in the array utility.
So i'll just need to remove it, following your steps.

BTW, thx for being specific, coz this is exactly what i needed :).

LOL My Pleasure I'm an HP reseller so Ive done this a fair amount :)

if its an unassigned disk you will not have a problem (if it were part of another array it would have to be system erased using either the acu or the smart start CD - but as it was flagged "unassigned" you wont need to do this"
