In CTRL-R, on the PD MGMT screen, does it list your new drive?  Or in OMSA, on the Physical Disks screen (Storage, PERC, Backplane/Connector, Physical Disks)? If not, does the light come on on the drive?  If not, are you sure it is mounted in the caddy/carrier correctly? What model is the drive?  Is it a Dell-certified drive or generic/retail?
I have a PowerEdge R510 with a PERC 6/I controller that had 4 300 GB SAS drives set up as a RAID-10. One disk was failed, so I bought a new one HITACHI HUS156030VLS600 ( 300 Gb )  however the RAID did not start rebuild process and I notice that BIOS/OpenManage just  dont see  it as a physical disk,  it shows only three physical disks.  Tech specification: Controller: PERC 6/i Integrated, Controller Firmware Version: 6.3.3.0002 BIOS: 1.6.3 Please advise what next need to be checked?
