Looks like this is a hardware RAID device, so raw access to the disks isn't available. You'll need to use Highpoint management tools to get drive-side information through it.

Same problem exists on Adaptec, LSI MegaRAID, etc.

I did that but I cannot figure out how to map the drive using freeNAS to the drive using the Highpoint tool. From freeNAS I get "da2" and from the Highpoint tool it gives me "Device_1_21" I do not see anyway to map a "da" to a "Device_".

When a disk goes bad FreeNAS tells me which "da" is bad so I need to know how this maps to the "Device_" so I can get the serial number so I can find the bad disk.

Right, you would need to use a Highpoint management tool to retrieve that information. I am not aware of whether one exists for FreeBSD for their products, you will have to check their support website.

I just stated I am using the Hipoint management tool but disks are revered to as "Device_1_25" for example. How do I map that to a "da" device which FreeNAS uses. That is my question.

  • Status changed from Unscreened to Closed: Behaves correctly

This is evolving into a usage question, not a bug. You might find more assistance on the forums where other Highpoint users can tell you how they solved this problem.

Going to mark this "Behaves correctly" for now, but if there's a change that FreeNAS can apply that would help your situation feel free to update this ticket.
