If you have anything attached to it, it should have a field called Enclosure showing the device, i.e MD1000 or so on. Under that should show the bays in said enclsure.
Hi, On dell server OMSA I see  SAS 5/E controller. As I don't see disks under this controller does it means that RAID is configured somewhere on external SAS disk controller in separate external enclosure and then it is connected to server's SAS 5/E by SAS cable?  thanks
