DL380 Disk Array

Ray Lee_2 — Sun, 10 Jun 2007 10:40:01 GMT

I have a DL380-G3 with 6x76GB-Raid5 hard drives and I am running out of space. I have some 146GB drives that I would like to replace the 76GB.

What is the procedure to replace each 76GB drives with the 146GB?

Thanks,

Ray Lee

if you cannot stop your system in order to make a back-up, replace the HDs, rebuild the new raid and restore, ...
you have to replace the HDs one by one, waiting for the rebuild process ends, each time.
after of that, you can expand your array...

i just did a very similar upgrade on an ML350-G3 server. the Jackal suggested i use Acronis Disk Director 10.0, which worked great. My drawback was that my server only has one logical drive with 4 partitions, including the system partition. the system partition was the only partition i was not able to extend. a rebuild and restore would be the best way to do this upgrade, but i needed to keep my server up and running, so i ended up replacing one HD at a time and used ACU to expand the new drive space and then Acronis Disk Director to extend the data partitions. be aware that the whole process can take a few days. it took about 3 days just to replace the HDs one by one. it took another 2 days to expand the drive space. it took about 1 hour of server downtime to extend the array. so, if you want to do this without rebuilding your array, here is the process i used.

-make a good back-up.
-test your backup to make sure it is good.
-replace drives one at a time. check your system log to see when the drive status is ok after each drive is replaced. do not replace the next one until the previous is ok. first drive takes the longest.
-use ACU to expand your array.
-extend your array. use dikpart (if your system drive and data partitions are on different logical drives). use a third party software, like Acronis Disk Director, if all your partitions are on one logical drive.
-after the upgrade is complete, randomly check data on the server to see that everything is ok. check any license-shared software to make sure they still work.

I don't particular like either of these procedure since is our Rapid Deployment Server. Plus I find out this morning that it in RAID 1+0. So not clear if your suggestion will work.

Maybe it's time to install HBA's in this system.

Thanks for your advice....rel

I have started the process of remove one drive at a time.

One of your steps says:

-use ACU to expand your array.

I don't see the option to expand the array in ACU.

if you know which one are mirrored, you can swap HHDs 3 by 3 ...

in two steps you can finish the job.

All drives are installed and I see the new Unused space. I did not see the expand array, the only command I saw was to extend the array.

I tried DISPART but it tells me I can't extend this volume.

I must have missed a step or two.

THanks

Are you trying to extend the boot partition? Diskpart can only extend data partitions:

So, my Raid 1+0 which had 6x72GB drives and we replaced all 6 with 146GB drives can't be expanded without a third party software?

Might be easier to rebuilt the system? Well not really since it is my RDP server.

Okay thanks all!

Re: DL380 Disk Array

Mauro Rusignuolo — Tue, 12 Jun 2007 08:47:46 GMT

only if you have to extend boot partition.

Re: DL380 Disk Array

Ray Lee_2 — Tue, 12 Jun 2007 09:07:04 GMT

Well the person that built this system made all drives Raid 1+0 and boot partition.

Fun fun!

Thanks for all the replies tho....
