Problem:

I was having issues where no disks were detected after upgrading to 6.2.0-beta21 from 6.1. When I looked at the unRaid syslog, I saw this:

mpt2sas_cm0: failure at drivers/scsi/mpt3sas/mpt3sas_scsih.c:8592/_scsih_probe()!

 

Setup:

I'm running unRaid on ESXI 6.0 using the PLOP boot method. I have my hard drives attached to a m1015, which is flashed to LSI9211-8I IT mode (running I think firmware v20). Also the m1015 is setup for passthrough in ESXi to unRaid.

 

Solution:

I believe the drives not being detected is due to the firmware version. I did not attempt to downgrade the firmware. After reading posts from others, this is an issue with 6.2 and ESXi passthrough. Not a firmware issue.

 

After much research, I found someone having similar issues with running Ubuntu on ESXI w/ passthrough. The workaround solution was to add mpt3sas.msix_disable=1 option to the syslinux config. See full syslinux config below. Drives are now showing up as normal. Hope this helps someone else 

 

Syslinux Configuration:

default /syslinux/menu.c32

menu title Lime Technology, Inc.

prompt 0

timeout 50

label unRAID OS

  menu default

  kernel /bzimage

  append mpt3sas.msix_disable=1 initrd=/bzroot

label unRAID OS GUI Mode

  kernel /bzimage

  append initrd=/bzroot,/bzroot-gui

label unRAID OS Safe Mode (no plugins, no GUI)

  kernel /bzimage

  append initrd=/bzroot unraidsafemode

label Memtest86+

  kernel /memtest

 

Interesting, I'm going to have to give this a try on my setup and see if it works since the hardware passthrough not working is the only thing stopping me from upgrading to 6.2.

 

EDIT: It worked!  Thanks for this.  Upgraded my backup server to 6.2 and will do some testing over the next week to determine if it's stable enough for me to upgrade my main server as well.

That's awesome! Glad I was able to help. 

 

I'm still not 100% sure if disabling MSI-X is a big deal. Let me know if you run into any issues...

 

According to the discussion here, this is an ESXi bug and will be fixed in the 6.0p3/5.5p8 release.

 

Special thank you for sp1k3ster as well

Thanks so much for this, and for reaching out! 

This would only solve the LSI card passthrough, correct? Is there a way to disable MSI-X on other drivers? I passthrough my NIC card as well

Thanks for this post, I am now upgraded from 6.1.9 to 6.2 RC1 

This worked for me also. Thanks much. Are there any potential negatives to this workaround?

Awesome!  Nice work!  I can't wait to try this and report back.  Thank you.

Is this still required with the release version of 6.2?

 

I'm currently running unRAID 6.1.9 as a guest on vmWare ESXi 6.0.

 

Thanks,

Yes. This is still required after the release of 6.2.

 

I implemented your solution for the m1015 and it resolved the issue.

 

 

Here is a link to my VMDK with the solution already implemented:

unRAIDServer-x86_64_v_6_2

Yes. This is still required after the release of 6.2.

 

Thanks.  I'll have this in my bag of tricks when I next set aside time to troubleshoot an upgrade.  Any idea if this configuration change would be required for this card?  This is the one I'm currently passing through to my unRAID VM.  It's not a great card, but it serves my needs for now, until I need more or larger drives.

I would suggest that you upgrade and post your log files if you have an issue. I am not familiar with the sas3041e-r card.

It worked like a charm on my 6.1.9-6.2 upgrade.

 

Thanks a lot sp1k3ster !! 

 

Thanks for this.  Glad I kept this thread opened in a tab in Chrome.  When I upgraded from 5.x to 6.2, I rebooted the Unraid VM but didn't reboot the ESXi box.  Today I figured I should just to see if I would run into this or not and I did.  After ESXi and Unraid came back up, no disks were found.  Made the changes in the syslinux.cfg, rebooted and drives were back.

 

Thanks again.  Without this, I would have been really frustrated

Yes. This is still required after the release of 6.2.

FYI - I upgraded my unRAID VM on ESXi 6.0 from 6.1.9 to 6.2.1 today, and did not need to add this boot change.

The driver on my machine (what I see when the physical machine boots) is:

  LSI Corporation MPT SAS BIOS

  MPTBIOS-6.22.00.00 (2008.04.10)

  Copyright 2000-2008 LSI Corporation

 

But thanks to this thread, I was ready in case I needed it.  I did also restart my ESXi server in the process.
