I've got a Dell PowerEdge 2950 running Windows 2008 R2. It has a PERC 4/DC that's connected to a PowerVault 220s. The PowerVault used to be in split configuration mode. I've removed its secondary connection and it's now running in joined mode.
When I boot the PowerEdge and go into the PERC configuration, I can see all of the drives. Half are already configured as a RAID-5, and I want to extend the RAID. The documentation I have says that I can do the extension by using the Dell System Administration tool. Unfortunately, when I run the tool, it only detects a PERC 6/i on the system, not the PERC 4/DC. I have checked the PERC driver and it's running the latest version I could find to download from Dell. It's signed by Microsoft and is version 6.1.7600.16385. The Dell Server Administrator is version 220.127.116.11.
I believe I have several options:
1. Find a version of Dell Server Administrator that will detect the PERC 4/DC.
2. During boot, clear the RAID configuration and build a new configuration with all of the drives.
3. Replace the PERC 4/DC with a PERC 4e/DC I have on hand and see if Dell Server Administrator can see it. The documentation shows that the PERC 4/DC is a PCI 2.2 card and the PERC 4e/DC is a PCI Express 1.0a card, so I don't believe that it's possible.
4. What other RAID cards are compatible with a 2950 server and a 220s PowerVault?
