MPSS and MICRAS service failure

Dear all,

I'm working with Xeon Phi 7120. I tried to restore the MPSS configuration to default values and have executed the service mpss unload and cleanconfig (sudo service mpss unload and sudo micctrl --cleanconfig, respectively) but the sudo micctrl --initdefaults and sudo service mpss start don' start the mic's and mpss. I receive "exit-code" on micras.service and mpss.service.
Any help is most welcome.
Thanks.

most likely the mic.ko module did not load.

Please provide some info on the OS you are using and attach the output of "micdebug.sh"

Hi JJK.
Thanks for your reply.
The OS is RedHat 3.10.0-693.el7.x86_64.
I can't run the micdebug.sh due to the MPSS config is not found. I tried to execute the micctrl --initdefaults but it gives an error as no MIC cards are found or specified.
I've attached the mpssd file from /var/log to see the errors.
Thanks.

Cheers,

João Rocha

there is something seriously wrong with your software stack installation. The mpssd log shows

  12025 Wed May 30 10:07:28 2018: mic1: Ignoring  - Critical failure reading state sysfs entry
  12026 Wed May 30 10:07:28 2018: mic2: Ignoring  - Critical failure reading state sysfs entry
  12027 Wed May 30 10:07:28 2018: mic3: Ignoring  - Critical failure reading state sysfs entry
  12028 Wed May 30 10:07:28 2018: mic4: Ignoring  - Critical failure reading state sysfs entry
  12029 Wed May 30 10:07:28 2018: mic5: Ignoring  - Critical failure reading state sysfs entry
  12030 Wed May 30 10:07:28 2018: mic6: Ignoring  - Critical failure reading state sysfs entry
  12031 Wed May 30 10:07:28 2018: mic7: Ignoring  - Critical failure reading state sysfs entry

that suggests that you have 8 mics present (counting start at 0) yet all of them have a "state sysfs" issue .

I'd suggest you reinstall (at least) the mpss-modules package and then reboot.

Or, better safe than sorry, update to the latest release (3.8.5)

Hi JJK,

Thanks for your reply.
I've done the micctrl --cleanconfig because of those errors/issues.
I'll install the latest release 3.8.5 of the mpss.
Thanks a lot.
Cheers

Hi JJK,

 

I've noticed that the 3.8.5 version of mpss is not supported for rhel 7.0 (my version of the rhel OS).
Should i try to install it anyway?

Thanks.
Best regards,
João Rocha

your kernel version, RedHat 3.10.0-693.el7.x86_64, is supported by mpss 3.8.5 so I'd simply try that one.

Also, if you still experience problems after reinstalling the mpss stack (most notably, mpss-modules) then try loading the mic.ko module manually (i.e.   "modprobe mic") then post the output of "dmesg"   so we can have a look at what is happening/failing.
