Force RAID 1+0 HP Smart Array to rebuild

Question

I have a RAID10 with status "Ready for Rebuild", but how can I force the rebuild?

You can't.

"Ready for Rebuild" status means that the rebuild is likely running into a read error from a partner disk. You may have another failing disk in the array. See: Force LUN in a HP Smart Array to rebuild

Did you recently replace a disk?
Please provide the firmware revision of the Smart Array E200i controller you're using.
Please show ctrl all show config detail

I'd check your backups and schedule time to power the system off and back on again. This could be a firmware issue, depending on what happened before this, or you may have the failing disk situation described above.

Thanks for the answer! - Yes, we changed a failed disk - Firmware 1.78 - I edit the original message with 'show config detail' - We let the machine power off for a while, and then turn on again, but with the same error :( – Tiago Cruz Sep 30 '14 at 14:42

Try updating the controller firmware. The current version is: 1.86 – ewwhite Sep 30 '14 at 14:47
After the firmware upgrade and reboot, the recovery begins: logicaldrive 2 (2.0 TB, RAID 1+0, Recovering, 1% complete) Let's see if they will finish :) – Tiago Cruz Sep 30 '14 at 16:27
Using Firmware Version: 1.86, after the reboot, the status is "Ready for Rebuild" again :( – Tiago Cruz Sep 30 '14 at 17:42
@TiagoCruz Then you likely have a failed or failing disk in the array with read errors. There's also a slight chance that you need a disk firmware update. But at this point, you may not have options. – ewwhite Oct 07 '14 at 13:29
