I=E2=80=99m having a problem with eSata cards and AHCI on a FreeBSD 11.0 =
RELEASE test box. I=E2=80=99ve been running a generic dual port eSata =
card from StarTech, with a 4 bay Mediasonic (port multiplier supported) =
enclosure on one port and a single bay generic enclosure on the other. =
Everything has worked fine with that configuration. However, I=E2=80=99m =
trying replace the single bay enclosure with second 4 bay Mediasonic =
enclosure. The StarTech card apparently doesn=E2=80=99t support two pmp =
enclosures, so I=E2=80=99ve been experimenting with different eSata =
cards. The current one is a Syba SD-PEX40049 2 port card based on the =
ASM 1061 chipset. The original enclosure has 4 drives (in a zfs raidz =
configuration) and the new enclosure has 3 drives.
When the machine is booted, the bios on the eSata card sees all 7 disks =
and reports them properly to the console, and in fewer than 2 seconds.
After the reboot, none of the 7 drives appear in the machines device =
list, although the card itself appears as ahci0 (see below for the =
pertinent dmesg segments). Note also that FreeBSD itself is on =
internal ufs drives, so the machine boots fine, it just doesn=E2=80=99t =
see the drives in the two external enclosures.
After logging in, I then run camcontrol reset 0 (actually, sometimes I =
need to run it several times, and sometimes I need to run camcontrol =
rescan 0), and finally the first four drives appear. Then camcontrol =
reset 1 typically makes the other 3 drives appear. See the dmesg =
segment below after running these commands. =46rom then on the machine =
seems normal
Here are my questions:
1. Is this a controller issue?
2. Is this an issue with the controller card?
3. If so, is there a recommended eSata card that works in this =
configuration?
Any help in debugging this would be greatly appreciated.
Boot dmesg segments:
