What controller are you using in the R510, and what firmware is it on? Support for over 2TB of storage may require the latest firmware. You can check your firmware version in the PERC BIOS, or in OpenManage (if you have an OS installed). The Lifecycle Controller may also display it through the Platform Update wizard.
Controller 0ERC 6/i Integrated Bus 0x02 Dev 0x00 Fn 0x00 Slot 0x04
PERC 6/i Integrated BIOS Configuration Utility 1.22.52-1909
Any ideas for me?
That firmware should be the latest version, however, the issue is the controller itself, the PERC 6i. It doesn't support drives above 2TB. If this is something you have to have, the simplest solution would be to swap out the current PERC with an H700 on the latest firmware. That would let you get the storage up and running.
I'll look into it. I'm not 100% about it, but that does sound unusual. Are you able to use disks 6 and 7 for any other virtual disks, or are they seen and entirely inaccessible?
I didn't see in any of the documentation anything about those slots, or a disk limit for the controller. If you want to deploy a RAID 50 and then export the RAID logs, you can definitely upload those to a tech sharing site.
