Expand a virtual drive on a Dell Perc 6/i Raid 6?

Jump to solution

Hello,

I've got a PowerEdge T310 with 4 hotswap drives (raid 6), and its running dangerously low on space..

Can I just purchase 4 new larger drives, and (one-by-one) replace the old ones?

Can I expand the virtual drive or will I have to create a second virtual drive with the new free space?


Thank for you help

Hello Michael,

You can’t just purchase new drives & replace them one by one & see the new space. Now what you can do is to replace the drive one at a time & then do a reconfigure. To do a reconfigure you will need to be using open manage 7.1 or higher you can click on the virtual disk and do a reconfigure. When you go into the reconfigure you should see the option to expand using the available space. Now it is best to get a backup before attempting this just incase you run into any issues with it.

Please let us know if you have any other questions.

I was looking for this exact answer but: if I already replaced all 5 of my RAID5 drives with bigger drives (one at a time), can I now do a reconfigure to increase space on the virtual drive? Or do I have to go back to the original drives and add/reconfigure them one at a time? Thank you! Robert Quinn Culver City Unified School District

This needs to be done one drive at a time.  your RAID5 controller set can only function properly with the loss of one drive.  This means that if you replace one drive your RAID array will be in a critical state.  Replacing the drive with a larger capacity will then require you to reconfigure your VD aforementioned.

If you were to remove all 5 drives and replace them with larger drives the array has no way to understand the configuration changes since you have removed your parity drive. Put all 5 drives back and replace them one by one.  Remove one, insert new and then reconfigure VD - repeat.

Never remove/replace more than one disk at a time in a RAID environment.

Thank you for the help. I had replaced them one at a time, monitored VD status in Server Manager until each drive was rebuilt, then replaced the next one. Seemed like everything was working ok will all 5 drives replaced, VD status was green. I'm glad I asked here before going ahead with the "reconfigure" process...

Ok, I'm more confused now: when I had replaced all 5 drives, one at a time, then started the "reconfigure", it showed all 5 drives with available free space. Now that I have gone back to my original drives and only replaced one, "reconfigure" shows 0 free space, even on the new drive, so there isn't any reconfiguring to be done. Can I ask what I'm doing wrong here? Thanks, I really appreciate the help!

Hello RobertQuinn,

Here is the Supported way of getting the extra space for your system.

1) Get a backup of your data

2) Delete array

3) Recreate array with big drives

4) Reinstall OS if have an OS on the Array before

5) Restore data from backup

Now there is also an UNSUPPORTED way that you can do this as well & to do it that way is as follows:

1) Get a backup of your data.

2) Rebuild each large drive to array.

3) After all rebuilt Delete array.

4) After the array has been deleted then do a Retag array

5) Do NOT init the virtual disk

6) Create new array with space avail

Please let us know if you have any other questions.

Thanks again, one last question before I dive into the unsupported method: Can I do the array deleting and retagging from Dell Server Administrator or do I need to reboot and go into the Raid/Array software offered during boot?

Hello RobertQuinn,

Yes you can use Open manage server administrator to do this process. When you do a retag will be from bios. Also remember to verify no initlize of virtual disk.

Please let us know if you have any other questions.
