RAID 1+0 disk upgrade

Hi,

I have a few DL380 G4s. I have 2 x 74GB in RAID 1+0 which has two partitions, C: and E:. My E: partition is running out of space and wanting to upgrade to 2 x 300GB drives.

What's the best way of upgrading the disk?

Re: RAID 1+0 disk upgrade

If you mean replacing the 72 GB disks by 300 GB ones, it can be done one by one. Replace one disk, let the RAID 1 rebuild, replace the other.

You will end with a disk with the same partitions but 212 GB of free space. You can use that space to expand E: (that's a Operating System task, the RAID controller does not modify the partitions).

Re: RAID 1+0 disk upgrade

Hi,

Thanks for the response. That's what I've been reading and tried those methods and it was failing for me. At the time I was not sure why it was not working.

But it looks like I've got two faulty drives straight out of the box.

I've done a test build with a DL380, 2 x 36GB drives RAID1+0

- Removed one of the 36GB replaced with 72GB, let it rebuild
- Removed the other 36GB, replaced with 72GB
- Wait to rebuild
- Extended the disk using ACU
- Extended E: partition using diskpart

Thanks for the reply.

Just out of interest:
RAID 1+0 requires a minimum of four disks to operate doesn't it?

Not by HP's definition on SmartArray controllers...

Cheers,
