We have 4 x SATA drives in a RAID5 array controlled by a HP E200 controller.
We had a failed drive but couldn't get the controller to recognise any drive in the faulty port. Have tried new cables and controller port (no backplane) and finally changed the controller in order to try and rebuild the array.
I managed to get the array to be recognised, albeit in the failed state, in a new controller. Im just reinstalling the OS on a separate drive not running through the RAID card (PCI) and with the few times I've powered it on and off it now shows logical drives as 0 when it's initialising.
I've now got 2008 R2 running on the old ML110 G5 server and have installed the HP Array Configuration Utility but in there it just shows all the drives as ok and shows them all as unassigned drives which scares me to death as i have no backup of the data.
How can I best attempt to rebuild this, I'm not very competent with these arrays so apologise if i've missed something obvious.
