[OpenIndiana-discuss] sata hot plug problem (ahci?) + openindiana crash
Hello,
I've trying to insert a sata hd in an enclosure, but it doesn't seem to be
recognized by the os.
Low and behold, I used '# cfgadm -al', and only usb devices come up, nothing
sata related.
I have several sata hard drive in that machine, all of them contributing to a
zpool which work perfectly fine.
So I don't know why they are not showing up with cfgadm?
I read a bit about the topic, and it seems to depend on ahci being available.
I ran '# dmesg | grep -i ahci' and nothing showed up
The motherboard is msi 890FXA-GD70, and I went in the bios:
integrated peripherals - on-chip ATA devices - RAID Mode : {IDE, RAID, AHCI}
and switched from IDE to AHCI
I then restarted the machine. I got the booting screen for about 5 sec, and
then the machine reboots.
I switched back from AHCI to IDE, and this time the machine booted fine.
So I'd like to know what needs to be done to be able to swap sata drive in
that machine...
Thanks,
Matthieu

Hi there,
I have been on the same spot. Some Motherboards that have more than 4 SATA
ports, with less than 5 disks there is no problem but if you want to use
the fifth port you need to choose AHCI or RAID in order to make it
work.Also, check for errors on the dmesg. I had tons of problems with IDE
mode and Openindiana as i installed the OS on AHCI mode. I have to change
the config every time that my BIOS gets cleared.
Best regards

Well, if your disks were indeed used by the BIOS in IDE mode, the SATA driver is not used, and you'd likely see the pci-ide driver names like cmdk in your other disk names. AFAIK the disks should be recognized automagically upon boot, and if not - try running devfsadm -Cv to detect devices and add/remove the links in /dev dir. ... and switched from IDE to AHCI I then restarted the machine.

So I'd like to know what needs to be done to be able to swap sata drive in that machine... This usually means that your root/boot disk was also changed from IDE to AHCI, and this does interrupt the boot procedure. The lowlevel issue is that the driver and device names for disks change, rendering invalid those names used in the rpool config carried over to the miniroot image (boot_archive). There are workarounds, likely posted in archives of zfs-discuss list and many other sources. If I google anything good up, I'll post a link here :) HTH, //Jim Klimov ___ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
