Make sure to move *all* disks from a raid set. This is called roaming.

Thank's for quick reply ,but the case is to move only some pairs not all the pairs. Because some of these pairs are virtual machines (Hyper-v) that uses physical hard disk's and in case of server hardware failure we want to move these VM'S. Thank you.

All disks means for a RAID 5 all disks of this RAID5 or in your case all disks of this RAID0+1.

You mean all 4 pairs? Because when i did it with one of the pair's i had the error and while entering the raid setup on boot there was no more raids or logical drives. Thank you.

How are the 8 disks setup in the first server? Are they 4 different raid1 groups (mirrored pairs) or one raid10 group (mirrored pairs - striped)?

Please check in the first server with ACU and provide details.

This is exactly the point. Please attach ACU screen shot of physical view.

The two servers are identical meaning that on the first server i have 4 pairs of disks that are raid1, just mirror not other type of raid. The same is also the second one. I will try to get a screenshot also.

mirror sets by two.

So what do you do in the second server if you also have 8 disks in it? Do you simply pull out two disks and insert the two disks from the first server?

In the second server you should go in the ACU, unconfigure the two disks that you want to remove (delete any OS disks, LUNs etc), have the second server good and healthy with two available disk slots and then you insert the disks from the first server.
