Hi all,
I have done a bit of digging in the archives and find lots of related
issues but no working solutions. I don't know if this should be
considered a bug or not so help is appreciated.
I have a sil3124 chipset PCI card flashed with base(non-RAID) BIOS.
Connected to this card I have a sil4726 chipset 5 drive enclosure with
up to date firmware. The enclosure has been configured using a Windows
machine with 2 750GB drives in RAID 1. So a host PC should see 1 logical
750GB drive + configuration drive if my understanding is correct. I have
tried many of the latest kernels but the drives are not detected correctly.
At the moment I have just tried the latest fixes at upstream-fixes @
git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev.git
Attached below is a dmesg log with the above specified kernel for the
following action.
1) Boot computer
2) Begin recording dmesg log
3) Turn on sil4726 based drive enclosure
4) Wait for dmesg activity to settle
5) Stop logging
At the end of the process I have no additional disks in /dev/sd*.
Does anyone have any suggestions or any troubleshooting steps that I
should try? What can I do to provide more useful information?
Ah... please don't use hardware RAID mode w/ 4726. Just use it as plain
Port Multiplier. Its ATA device emulation is really bad and just can't
work with a generic driver. We had to disable even the Config Disk
recently to work around some detection issues.
Thanks.
