I'm with Jose on this, and in any case, I think you'd be better off not taking the huge hit that rebuilding a RAID5 of this size is going to take, and risking a disk crapping out on you during rebuild and losing it all anyway.

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.

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. -DaveC Reuters IS&T Service Delivery From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Al Mulnick Sent: Tuesday, August 23, 2005 8:18 AM To: [email protected] Subject: RE: [ActiveDir] OT: HP disk upgrade.. 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. Al From: [EMAIL PROTECTED] on behalf of Frank Abagnale Sent: Tue 8/23/2005 4:04 AM To: Active Subject: [ActiveDir] OT: HP disk upgrade.. 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 __________________________________________________ Do You Yahoo!?
