Hello. The management of RAID controllers and arrays is not done in iDRAC or systems BIOS. For management of RAID arrays (Virtual Disks), you need OpenManage Server Administrator (OMSA). If not installed, see link: [URL]                                                                                                                                                                                                        Once installed, go to -> Storage ->Controllers -> PERC H330 -> Virtual Disk -> under Available Tasks -> select Reconfigure and Execute -> then check a box to add the fourth drive on the next page. Follow the prompts and this will enable you to expand your RAID 5 array.
 Hello all,  I have a PowerEdge T330 server with 8 drive slots and currently have 3 SATA drives running a raid 5 configuration.  I have a virtual disk configured for the Raid (you have to). The operating system recognizes the disk and is able to use the resources.. My desire is to add another hard drive to the array (all hard drives same size, same make, etc) making 4 drives without losing any data. I have looked in the iDrac settings and the only setting was to add the new drive as a global spare or a dedicated hotspare for the virtual drive. I have also looked in the BIOS and do not see a way to add the new drive. Does anyone know how to expand the capacity?  I can blow away the virtual drive if needed and start over without issue.  I have plans to incrementally perform this act until adding 8 drives.(5 additional times). Help!
