Hi David,
Since you fail to mention which MSA your running ( MSA500, MSA1000,
MSA1500 ) it is difficyult for me to tell you if this will work as I have
only implemented and supported a MSA500 and a MSA 1000. We just ordered a
new MSA1500, but it has not arrived yet.
My understanding of HP's RAID controllers is, you can add the 300gb drives
if you add them to the existing array, you will only rebuild them utilizing
the same drive capacity as the drives you are replacing.
Therefore unless HP has implemented a new feature that I am not aware of,
you will have to clear your RAID config from the controllers NVRAM, and
recreate the Array using the 4 300gb drives. Or if you have 4 available
slots, you should be able to create a second array of the 4 new drives
virtually, and move your data between both RAID array's.
Jose :-)

I didn't see mention of RAID controller or O/S version, but do they support
logical drive extension? If so, how about this? (though probably not much
faster!)
- Backup data (if important enough...as you said this already is a backup)
- Remove one physical drive from the enclosure
- Replace it with a 300GB drive and let it rebuild completely
- Repeat this sequence 3 more times until all drives are 300GB
- Extend logical drive to full capacity via array config. utility
- Do same under O/S (Win 2003 "dispart" utility is good for this)
Just a thought.

I believe that since they are backups, you have some flexibility. For one
thing, you can move the data around and store it on just one disk if you
wanted to ([EMAIL PROTECTED] ~216GB vs. one 300GB disk) and then after the
upgrade, move it back. I'm sure there are other variations.
It would seem a little odd to backup a backup in order to accomplish this.
You pretty much just need some temporary space while you do this.

Hi,
Sorry for the OT, I have a HP server with an MSA enclosure attached which is
complete with 14 x 72gb disks. The enclosure uses 4 x 72gb disks in a RAID5
set which are used to store backups. I need to upgrade these 4 disks with
new 300gb disks. The disks are not used for any other purpose besides
storing backups.
My initial thought was to do the following:
Backup the drive
Break the array
Remove existing disks
Insert new disks
Create new Array
Is there a better way to do it, or should this method work?
thanks
- Frank
