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

| 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 (4xRaid5@72gb ~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 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,

| Well you need to stash the data somewhere while you change out the disks. Having your DAS unit being tapped out just makes this a more time consuming process. If you have some sort of enterprise backup solution (e.g. netbackup) you could just do a one time job and grab the entirety of the volumes on these disks. If you don?t have some sort of backup system (ok, we shouldn?t be following this part of the answer), you could run ntbackup, and stash the ntbackup somewhere on the network, or elsewhere on the array if you have room. Then, you need to just do the music drives, format the disk, represent it to the OS if necessary, and restore the data from wherever you stashed it.
Not too hard really, just plan on lots of time if you don?t have local storage for it ? it takes a while to move 220GB of shit across a 100MB link.

| 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.
Thanks,
Brian Desmond
