It depends...
You can replace the drives one at a time, then extend the array and
logical disk using the HP ACU. Once the array is extended, you can then
use DISKPART to extend the disk. No down time required. If you do
this, you are taking the chance that you won't lose another drive while
the array is rebuilding each time you replace drive, but I have done it
and it is pretty painless.
The other way is to blow away the array, put your new drives in, create
a new array, create a new disk, format and recover your files from
backup. This way you know you will have down time and schedule it.

Subject: increase server storage
I have an HP Proliant server w/ (4) 74GB SCSI drives in a RAID 5.
This gives me a single 203 GB logical drive.
I would like to increase storage on this server to as much as possible.
I see that there are 300GB SCSI drives that are available for this
server (about $1000 each).
So my question is... what is the best way to do this?
Remove the 4 74GB drives and replace them w/ 4 300GB drives in a new
RAID 5 configuration?
The current 1 logical drive is D: on Windows 2003 server, and only
contains a single Firebird SQL database file.
