mic0 unresponsive to icmp requests

[Sunn_A_]

Hi ,

I am working on MPSS3.2.3 and this command "micctrl --resetconfig" is giving me hard time going ahead.

I was trying to do nfs  mount on the mic0 and executed the following commands for the setup :

service mpss stop

micctrl --resetconfig

service mpss start.

After executing the following commands , mic0 went unresponsive to icmp requests.

Uninstalling and re-installing the software was not much help and mic0 is still not pingable.

I am new to the MPSS so i was trying micctrl commands and i executed miccheck also and found something like this :

  Test 6 (mic0): Check running flash version is correct ... fail
    device flash version does not match, should be '390', it is '381'.

Status: FAIL
Failure: A device test failed .

Rebooting the host machine also didn't helped . The mpss service was still online. 

Please suggest how to proceed further. Also what all things get affected by executing micctrl --resetconfig as not much is given in the administration guide.

Thanks!

try updating the flash first:

micflash -update -device 0

prior to starting mpss (you should only need to do this once).

I tried the following

/usr/bin/micflash -update -device all -smcbootloader  

 Now the micchek passes. 

But still mic0 is unresponsive to ping requests.

After the flash update you need to restart the mpss stack (or reboot the server).

Then run a 'micctrl -s' to check the status of the Phi. If 'micctrl' reports running then you should be able to ping the XeonPhi

I'm afraid the Sys Admin Guide is way out of date. It refers to MPSS 2.1. The good news is the 3.4 version guide is going through final review and should be out there soon.

As to your original issue - as Jan pointed out, you need to reboot the host after updating the flash on the card. If you are still having problems, please check your configuration files on the host and coprocessor. Make sure the  /etc/hosts, fstab and interfaces are correct on both host and coprocessor - you can find the coprocessor files in /var/mpss/micX where X is the coprocessor number. Make sure the exports and host.allow are correct on the host. If you find any problems, you can correct them by hand or use the network configuration options to micctrl that you find in the MPSS Users Guide (comes with the MPSS).

The resetconfig option to micctrl will modify some of the Linux configuration files unless you add '--modhost=no --modcard=no'. When it does this, it returns these files to simple default values, probably not the ones you want.
