Intel Rapid Storage Technology/RAID not being recognized on Dell Optiplex 7060

[tehresman]

I’m trying to use FOG with some new Dells we just got in. So far I’ve changed the SATA mode to AHCI and even used the Dell recovery USB to try to get things as close to the factory default as possible.

I think my problem right now has to do with the Intel Rapid Storage Technology, but every forum post I find ends with someone asking a question to the person having a problem and then no response.

@tehresman Please schedule a debug capture task and when you get to the shell run lspci -nn and take a picture. Hope we get some valuable information on that RAID controller.

@Sebastian-Roth Here you go 3

Do you need raid mode on this desktop? If not switch back to ahci mode to capture and deploy the image. There is a known issue between linux, uefi, dell computers with intel raid adapters in raid-on mode. Change any of the two (you can’t change linux) and the image should capture and deploy correctly.

One other option is to use the F12 boot menu and pxe boot in bios mode (one time only) to capture/deploy to this device. FOG will capture a uefi disk image even if the target computer is running in bios mode.

@tehresman OK with the system still in ahci mode, do a debug capture/deploy. At the FOS Linux command prompt key in lsblk that will show us the block devices that linux sees.

What version of FOG are you running, or at least what FOS kernel do you have. If you don’t know at the FOS linux prompt if you key in uname -a it will tell you the version number it should be 4.xx.x, probably 4.19.3

@george1421 I actually reinstalled FOG yesterday to see if that did anything.

[george1421]

@tehresman Well the good thing is that FOS Linux sees the nvme disk in ahci mode.

Now with this system configured for ahci mode you can’t capture or deploy?

What is your exact error in this configuration. If you actually scheduled the task you really wanted to enter debug mode, you can single step through the task by just entering fog at the FOS Linux command prompt. You will need to press enter at each step, but it will also give you a chance to capture the error you see with your mobile phone. As it sits right now it should capture correctly.

Since you appear to have 1.5.6 there is a known bug with the nvme deploy script that under certain conditions the disk will not expand correctly. That issue should be fixed when 1.5.7 is released in just a few days.

@george1421 it fails reading the partition tables in AHCI mode and doesn’t even see the disk in RAID mode. I can get you pictures on Monday for sure though.

@tehresman It simply cannot find your disk/controller. It’s kind of strange because we have reports that it does work when changing from RAID to AHCI: https://forums.fogproject.org/topic/12906/dell-optiplex-7060-getharddisk-error

@Sebastian-Roth So just out of a combination of desperation and curiosity, I tried a different computer with the same exact specs. Changing to AHCI worked. The original computer works fine except for this one FOG issue. I booted into Windows, ran chkdsk, installed a program, rebooted and everything worked like there wasn’t a problem. I reinstalled Windows with the Dell USB recovery disk and FOG was able to pull an AHCI mode image. Out of 15 computers, two had this issue. I think this is a fluke with Dell. Thanks for both your guys’ help.
