PostPosted: Wed Apr 04, 2018 8:34 pm    Post subject: [solved] ahci only detecting 4 SATA Ports but 6 are installe Reply with quote

Hello!

I got a used SATA HDD from my old RAID system and connected it to my last SATA Port in the system: Port 5.
The BIOS is configured to treat the SATA HDDs as IDE disks and successfully detects my WD black HDD. But Gentoo doesn't

So i looked into dmsg and was wondering why the ahci driver only detects 4 SATA "slots":
Code:
[    2.199144] ahci 0000:00:11.0: AHCI 0001.0100 32 slots 4 ports 3 Gbps 0xf impl SATA mode
Can someone explain to me, why it doesn't recognize the 5th and 6th (E-SATA) port?

Thanks!

Here's some output which might help:

lspci, you may have a secondary SATA chipset.

Evil.2000,

Wild guess, Your AHCI controller is in IDE mode. Check your BIOS.

IDE mode is intended to be used once only by Windows XP users so that they can can install the AHCI driver.
IDE mode usually offers incomplete functionality. Only some parts work, no DMA ...

Thu giveaway is lspci.
Code:
00:11.0 SATA controller: Advanced Micro Devices, Inc. [AMD/ATI] SB7x0/SB8x0/SB9x0 SATA Controller [AHCI mode]

If you have IDE Mode where I have AHCI mode, its a BIOS configuration change. See page 3-21

Yes it is in IDE mode.

If I switch to AHCI mode in BIOS i get an grub error:
Code:
error: file '/grub/i386-pc/normal.mod' not found
Entering recovery mode...

If I switch back to IDE mode, it boots fine.

Evil.2000,

Switch to AHCI mode. Boot a liveCD and get into the chroot.
You will probably need to reinstall grub to the MBR.

Ok, thanks guys, this seems to be solved.

After changing to AHCI I needed to wait after the reboot for the "AHCI boot screen" to finish. After that the BIOS mixed up the boot order of the drives. Therefore I had to reboot and enter the BIOS again and rearrange the boot order.
Now grub boots up as before.
