Other Only /dev/pass*

Hello,

Drives plugged in to an Adaptec 51245 only appear as pass(4) devices. I have tried setting the drives up as JBOD or single drive RAID 0. Same results with both. Don't know what to do. I know the Adaptec card isn't the best thing to be using here, but I got it for free and I will not be using it as any sort of file server so I don't really care what happens-I would just like it to at least mostly work.

I will provide any information required later as I do not have access to the machine currently.
 
Don't think that is my issue. I've tried about 10 different drives. New WD red, old WD red, WD black, some Seagate, HGST he6, HGST ultrastar, HGST NAS, and 4 different SSDs.

The drives show up with camcontrol devlist but only as pass()* and in the cards BIOS.

If # camcontrol devlist shows the correct drive models, but no volumes show up as disk devices, that usually means that the controller isn't exporting them to the operating system properly. Here is an example with an LSI controller:
Code:
(0:15) gate:~terry# camcontrol devlist
<SEAGATE ST9146852SS HT66>         at scbus0 target 0 lun 0 (pass0)
<SEAGATE ST9146852SS HT66>         at scbus0 target 1 lun 0 (pass1)
<SEAGATE ST9146852SS HT66>         at scbus0 target 2 lun 0 (pass2)
<SEAGATE ST9146852SS HT66>         at scbus0 target 3 lun 0 (pass3)
<SEAGATE ST9146852SS HT66>         at scbus0 target 4 lun 0 (pass4)
<SEAGATE ST9146852SS HT66>         at scbus0 target 5 lun 0 (pass5)
<DP BACKPLANE 1.07>                at scbus0 target 32 lun 0 (ses0,pass6)
The actual disk device shows up as a mfi(4) device:
Code:
mfid0 on mfi0
mfid0: 557568MB (1141899264 sectors) RAID volume 'SYSDISK' is optimal
Is it possible that the disk is showing up under a device name you aren't expecting? Try doing # grep sectors /var/run/dmesg.boot (assuming you've got an installed and working multi-user FreeBSD setup, otherwise try # dmesg | grep sectors) to see if that is the case.

That matches your description.

It would seem that the volumes aren't being exported by the Adaptec controller for some reason. Do a # grep -C 5 -i adaptec /var/run/dmesg.boot, which should give you something like this:
Code:

pci0: <base peripheral> at device 8.0 (no driver attached)
Look for the line that says "Adaptec" in your output and locate the device name at the beginning of the line (in my example, ahd0). Now, repeat the grep(1) command, substituting the device name you found. In my example, # grep -C 5 -i ahd0 /var/run/dmesg.boot:

In my example, I have a tape drive and a media changer on my Adaptec controller. You should see some sort of disk volume(s). If you don't, the controller is not reporting any configured volumes to FreeBSD and you should go into the controller's setup utility and see if any volumes are configured, etc.
 
Thanks for the quick response.

Here is what grep -C 5 -i aac0 /var/run/dmesg.boot gives:

I have tried almost all configurations I have thought of in the controller's BIOS but I'll try again..
If you can't find any controller options that look useful, I'd suggest trying a Linux LiveCD, just to see if it detects the drives / volumes or not. That would help pin it down to either a FreeBSD driver issue or a controller setup issue.

This looks like you have aac_load="YES" or something similar in /boot/loader.conf. Try removing anything not absolutely essential to booting from that file and see if this error goes away.

I don't know why you're getting duplicates of this in the logging buffer. However, the first step will be to clean out your /boot/loader.conf and see what happens.

This, unfortunately (IMHO), is an all-too-frequent form of blather from the drivers (not restricted to aac(4)) at boot time, and de-sensitizes users to real problems. FreeBSD does this for CD/DVD drives and tape drives with no media inserted at boot time, as well as (new misfeature in 10.x) on mfid(4) member drives. It almost certainly isn't the underlying problem in your situation - the driver is asking the chassis "How many logical units do you have?" and the chassis is responding "I'm a chassis, I don't have logical units!". This repeats 5 times until the driver gives up.
 
It seems I have a similar problem:
Code:
# camcontrol devlist
<SEAGATE ST1000NM0001 0002>        at scbus0 target 0 lun 0 (pass0)
<SEAGATE ST1000NM0001 0002>        at scbus0 target 1 lun 0 (pass1)
<SEAGATE ST1000NM0001 0002>        at scbus0 target 2 lun 0 (pass2)
<SEAGATE ST1000NM0001 0002>        at scbus0 target 3 lun 0 (pass3)
<TEAC DV-W28E-R 1.0A>              at scbus3 target 0 lun 0 (cd0,pass4)

<PepperC Virtual Disc 1 0.01>      at scbus10 target 0 lun 0 (pass6,cd1)
I've tried the install media of Ubuntu Server 20.04 and it "sees" 5 hard disks.

Any ideas?
