If you have a RAID10 you need 2 Disks and not only 1 if you wanna to expand.   Regards,Joerg
Hello, I'm out an space on our server and I'm trying to add a new SSD to our RAID 10 configuration. When reconfiguring using OpenManage under Virtual Disk I get the following error... Error! Only even numbers of physical disks are allowed in this configuration. Is there a way around this or a different way to add my new SSD to the RAID? Thanks
