            Bug ID: 187381
           Summary: 4.9.-rc4 produces hundreds of unusable scsi devices.
           Product: SCSI Drivers
           Version: 2.5
    Kernel Version: 4.9-rc4
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Other
          Assignee: scsi_drivers-other@kernel-bugs.osdl.org
          Reporter: samuel.silbory@hds.com
        Regression: No

  --> https://bugzilla.kernel.org/attachment.cgi?id=244091&action=edit
Debian's kernel log file.  Note that this contains functional boots with older
kernels as well earlier in the file.

With both my hand compiled 4.9-rc4 from kernel.org sources and Ubuntu's
4.9.0-040900rc4-generic the kernel creates hundred of useless /dev/sd??
devices.  This system is fine with various 4.4, and 4.8 kernels.

The logs are spammed with messages like these

Storcli output from system.

Note that this occurs with really old firmware and the current megaraid
firmware.  The megaraid configuration is 12 one drive RAID zero arrays.

This was reported to the mailing list and should be fixed by this:

http://marc.info/?l=linux-scsi&m=147868920429684

We'll fast track this, but can you verify it fixes your issue.

Thanks,

Seems sane now.
root@pcsnode:~# uname -a
Linux pcsnode 4.9.0-rc4-1-default #1 SMP Wed Nov 9 13:59:28 PST 2016 x86_64 GNU/Linux
root@pcsnode:~# ls /dev/sd*

root@pcsnode:~# 

The only difference compared to 4.8/4/4 is the boot drive on the SATA controller ended up sdk instead of sdm (the last drive).  It's not an issue for me as I mount things by UUID

This was reported to the mailing list and should be fixed by this:

https://urldefense.proofpoint.com/v2/url?u=http-3A__marc.info_-3Fl-3Dlinux-2Dscsi-26m-3D147868920429684&d=CwICaQ&c=DZ-EF4pZfxGSU6MfABwx0g&r=4FOU_7YnNtQNKWSdicj67DITRyD0V0NPxX2P7qBxsr8&m=qqYheGXoM4mBPxyZZ7HM1rugSFukVAVfEjl1ifhaoqU&s=KCePcDLsNpEqob1iEoGGCb5Qf-smnMYk4XsK62Sp0h4&e=

We'll fast track this, but can you verify it fixes your issue.

--- Comment #3 from Samuel Flory Silbory <samuel.silbory@hds.com> ---
Seems sane now.
root@pcsnode:~# uname -a
Linux pcsnode 4.9.0-rc4-1-default #1 SMP Wed Nov 9 13:59:28 PST 2016 x86_64
GNU/Linux
root@pcsnode:~# ls /dev/sd*
/dev/sda  /dev/sdc  /dev/sde  /dev/sdg    /dev/sdi  /dev/sdk   /dev/sdk2   
/dev/sdk4  /dev/sdk6  /dev/sdl
/dev/sdb  /dev/sdd  /dev/sdf  /dev/sdh    /dev/sdj  /dev/sdk1  /dev/sdk3   
/dev/sdk5  /dev/sdk7  /dev/sdm
root@pcsnode:~# 

The only difference compared to 4.8/4/4 is the boot drive on the SATA
controller ended up sdk instead of sdm (the last drive).  It's not an issue for
me as I mount things by UUID
