DSM 6 - Missing 2 Disks

Recommended Posts

I have a Gen 8 HP server with 4 internal disks, these are fine.

I have 8 external disks hooked up to a box over external HBA connections. Each connection runs 4 drives in a single 8 bay enclosure with two links in the back.

 

6 disks are seen, 2 are not and it shows 2 available slots.

 

BIOS Post shows the drives

fdisk -l shows the drives

 

I have 5 USB devices, 12 drives, no eSata so:

 

internalportcfg="0xfff"
usbportcfg="0x1f000"
esataportcfg="0x00000"
maxdisks="12"

I created a RAID group with the 6 drives that are available so it seems the last 2 drives are the ones that I can't use:
