After inserting new drive can you check drive status on H710 Configuration utility or iDRAC. If it is showing as ready then you can create a RAID 0 with the drive. Is this a brand new drive or it is a used drive with configuration?
Dell PowerEdge T320 with PERC H710 Adapter Apparently you can't just simply insert a drive into one of the free slots on the front backplane and expect to use it as a regular drive, like for backups. So, with knowing this, can I create a separate RAID or VD for only this drive, so I can then use it to make a full, complete system backup of the current RAID 5? I started to try this, but then I got the message "It is recommended that all newly created logical drives be initialized...etc..." I couldn't find any place to initialize it, so I canceled to be safe.
