Hi, we had power outage and old HP Proliant ML350 G5 server wen't down. After power come back it shows that two drives from four disc RAID5 array needs to be replaced. Only one of the drives show red led error. We didn't have backup from this array. HP Smart Array controller is E200 in this one.

We had another HP Proliant ML350G5 with P400 controller. I took drives from broken old server and plugged to another server and it shows on Array configuration utility that three discs are online and ok, but it won't take the array back online, cause it shows that discs are on different bays. Even they aren't.

Is there a way to get the array back online? So we could get the data back.

When using HP ACU I can see that three discs are operational, but the one drive is disconnected from array. So one disc is broken, another shows ok, but is disconnected from logical array. Is there a way to attach that third disc back to the array without losing the data on discs

Now the three discs is showing as part of the array, and the one broken is missing from array. Still controller says the array is failed, any idea how to get it online and working?

If you have SmartStart CD and a USB stick you could generate a report through the ACU and paste it as an attachment here, I may be too busy to look at it today but someone else may tale a look.

By the sound of it though you're going to have to do data recovery if you don't have a backup. That involves getting a non-RAID HBA connected to each disk in turn to take an image of them, then de-striping with RAID reconstructor from www.runtime.org. Note however that RAID reconstructor doesn't always pick up the RAID layout with Smart Array controllers so you may have to pay runtime's support to do that via their raidprobe service.
