every disk manufacturer has its own logic card and dell never use any IBM disks as per my knowledge and exp, it is always a dell or a Seagate drive, the suggested action is to get a new drive and replace it.
I've run into an issue with a Dell R900 server. Recently, a drive failed and it brought down a VD at the same time. I have other SAS drives on hand, but they aren't Dell but rather IBM: the size is the same 300Gb, but the rpm is 15k instead of 10k. The drive appears as 'Ready' in OpenManage, I can't assign it as a global hot spare at all through the physical disk option in OpenManage.  After racking my brain trying to figure out why it won't rebuild, I noticed the capacity is showing as 263.75Gb, whereas all the other trays are showing 278.75Gb.  How can I get this drive to rebuild?  I'm at a total loss.  Do I have to rebuild it through ctrl-r ?? 
Dell R900 SAS drive failed, the new drive under capacity but is the same size
