Hi Frank,
I believe this (or very a question) has been answered in
the HP Support Forums.
I suggest you go to www.hp.com and go from there, search for MSA1000.
The MSA 1000 does not support full dynamic logical volume expansion
business, etc, you need
an ESA for that (rumoured in a "future firmware update").
Apparently you can replace each disk in a raid set individually, allow
the rebuild
to take place and then replace the next. Can take a long time (depends
on how busy the controller(s)
Is/are), but you can then use the extra space. I believe you can only
expand the last logical volume
or use the space to create a new logical volume.
There are issues to do with redundancy whilst the volume is rebuilding,
depends whether you have
RAID-5 or RAID-ADV(6) and standbys, etc.
You need to do a full backup before you do anything of course.
Regards,

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
