I'm not sure if this is the correct forum (or if it should be in hardware), but I thought I'd give it a shot here.  I'm setting up an older Acer H340 (small form factor server originally for WHS, with 4 internal bays connected to onboard SATA, and a Marvell 6121 running an eSATA port) to run unRaid 5.0 rc8a .  I also have a Sans Digigital TR4M external enclosure, which I used on the box under WHS.  The external enclosure works fine with 1 drive in the TR4M, but doesn't detect additional drives.  I did a bit of searching and found that I should add ahci.marvell_enable=1 to syslinux.config, however this still doesn't help.  I also have another machine that I verified it isn't a hardware problem with.

 

So currently, what I see:

    The machine boots, with only 1 LED on in the TR4M for the first drive.

    Drive 1 is added to the array, but Drive 2 doesn't show up in the unRaid console or unMenu, or as an sd[x] item under /dev  like the other drives.

    There is no change when I manually do the following commands (also suggested where I saw the syslinux.config change)

        rmmod ahci

        modprobe ahci marvell_enable=1

 

In syslog I see the following lines (first 4 I think are for the 4 internal drives, then the next ones are for the Marvell, where it lists 2 errors, but then appears to list ata5 and ata6 which I would assume would be the 2 drives in the external enclosure.

Later in syslog I see "up" messages for the first 5 drives, like the following, but only a down message for ata6 (which I assume is the 6th hard drive)

I'm not sure what else to check to try narrowing this problem down, so any help would be appreciated.

Here is the syslog, as mentioned it is 5.0 Rc 8a version on an Acer H340.

 

Hardware is as follows

  Intel Atom 230 @ 1.60 Ghz

  Intel 82801 GR/GH (ICH74) on board SATA Controller

  Marvell 6121 SATA Controller (drives the eSata port in use)

People here report that the TR4M doesn't work on the H340:

It actually worked in WHS with the Acer, and seems like the hardware should be supported since I've seen other references to it working with a change to enable AHCI on the Marvell controller, (in the syslog, and attachments, it seems to see all 6 drives connected, it just can't make the 6th drive available to emhttp in unraid, possibly because it shows the 6th drive with a link status of down for some reason).
