 Posted: Sat Oct 20, 2012 6:07 pm Post subject: kernel not detecting eSATA drive [solved] |
 |
|
I was previously having an issue where my kernel was picking up my eSATA drive and "bumping" other connected drives, skewing my RAID1 at boot and forcing me to resynchronize the array.
Now, I can't get my drive on eSATA to show up at all: at least not in Gentoo. It shows up in the BIOS just fine. My ASUS P7P55D PRO has two SATA controllers on it, one Intel and one JMicron.

The intel controller handles 6 on-board SATA ports, all of which have connected drives in RAID configurations. The jmicron controller handles the IDE CDROM and the additional SATA port, which is wired to my eSATA connector.
During bootup, dmesg shows the jmircon controller and the connected IDE CD-ROM: | Code: | ...

[ 1.744903] cdrom: Uniform CD-ROM driver Revision: 3.20 |
In the lspci output above, I noticed that there is no kernel driver listed for the AHCI instance of the JMicron controller. Could this be the reason for the drive not being detected? I've thought of changing the jmicron kernel driver to a module, but before that I though I'd post to see if anyone had any other suggestions. I'm currently using kernel 3.4.9.
Thanks,

if you look in bios you will find the jmicron can be in ide or raid or ahci mode. you may be able to select ide in bios to run the cd drive; you may be able to switch to achi in bios to run the esata drive; but you can't run one port in one and the other port in the other.

Sadly, that makes a lot of sense.
I changed the JMicron controller from IDE to AHCI in my BIOS, but it still picked up the CD-Rom and not the eSATA drive. I can't find any other options to change for the controller itself. Bummer. I haven't tried it yet, but I'm guessing the only way to get the kernel to choose the eSATA over the CD-Rom will be to actually power off the CD-Rom.
Looks like I'm going to have to find a board with yet another SATA controller to get my external ports working so I can have CD-ROM and eSATA at the same time. 
Thanks for the info Donahue.

| Jmicron sata part using the AHCI driver, not the pata_jmicron. Even you set controller to IDE mode, kernel will quirk it to AHCI mode. pata_jmicron is for the IDE interface. |

No, bios rules
