Moogs Posted February 3, 2017 #1 Posted February 3, 2017 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" Disk /dev/sda: 7.3

Kanedo Posted September 27, 2018 #3 Posted September 27, 2018 (edited) It's because your enumeration of your disks are not contiguous. Notice that /dev/sde and /dev/sdf is missing in your list When you set internalportcfg to 0xfff, this means you're assigning /dev/sda - /dev/sdl as disks 1-12. Because you have a gap in your enumeration (missing /dev/sde and /devsdf) it pushes the remaining 8 disks from /dev/sdg - /dev/sdn. Since /dev/sdm and /dev/sdn falls outside of /dev/sda - /dev/sdl, two disks won't show up. Easiest way to solve your problem is to simply increase the number of enumerated slots maxdisks=16 internalportcfg=0xffff usbportcfg=0x1f0000 esataportcfg=0x0 With this config, you're allocating disk 1-16 (/dev/sda - /dev/sdp) for internal use.
