DL360 G5 P400i Raid 5 SLOW

[hongman]

Also, is it possible to migrate back to Raid 1? When I look at the options in ACU the only migrate options are Raid5 or 0.

I removed the new drive and now its rebuilding again :/

You may have a flaky new disk. It is filing but in such a way the controller does not detect it. Find another new disk to install in place of this one.

> is it possible to migrate back to Raid 1?
No you can not take disks out of the array group. You can only migrate the raid type with the existing disks or any new ones you added to the controller.

> the only migrate options are Raid5 or 0.
With 3 disks that's all you can do. If you had 4 disks you could do raid1 (or 10).

looks like the new disk took longer as it has commenced rebuilding,(parity qued error gone now as you say ) have you looked in acu status messages

what does it say..

[marcus1234]

also run offline diagnostics,

ensure all disks have new firmware too

if issue persists and the above is doen reseat disk backplane, and all other components .

if it still persists try another disk as suggested

It was the hard drive!

I put the new one in and it commenced the array rebuild. Remember the previous rebuilds took over a day? This one took 45 mins lol.

All blazing fast, and HP are rma'ing the bad drive.

Funny how no diagnostic showed any fault.
