Procedure:MPSS setup

Upgrading to MPSS - 3.4.3

Step 1 - Preparation

get current info:

• mpssinfo > mpssinfo-mic.out
• Make sure root ssh keys are installed & ready BEFORE proceeding (Installer will look for them)

Step 2 - Uninstall current version

Unload current mpss module

• service mpss unload

Uninstall current mpss version (3.x)

• cd /path/to/new_mpss/
• ./uninstall.sh

Uninstall current mpss version (2.x)

• yum remove --noplugins --disablerepo=* intel-mic*

Make extra sure: rpm -qa | grep -e intel-mic -e mpss

Step 3 - Install new MPSS

Make sure kernel headers and devel packages are available:

• Install kernel-devel/kernel-headers package for running kernel
• cd /path/to/new_mpss/src
• rpmbuild rebuild mpss-modules-*.rpm
• cp /root/rpmbuild/RPMS/x86_64/*rpm ../modules
• cd /path/to/new_mpss
• yum install --no-gpgcheck --noplugins --disablerepo=* *.rpm

For v.3.3 and higher:

• cd /path/to/new_mpss/modules
• yum install --nogg `uname -r`*rpm

Load mic driver & init default settings

• modprobe mic
• micctrl --initdefaults

Step 4 - configuration

Edit /etc/mpss/*.conf as necessary

• micctrl --resetconfig

Host config

(put routing info here) - ip forwarding must be enabled on host to provide MICs with NAT access

• ...

- hosts.allow enabled - firewall allow enabled

• iptables -L

Must show -A INPUT -i micN -j ACCEPT

Step 5 - firmware checks

Check firmware version; DEVICE_ID are integers starting from zero:

• micflash -getversion -d DEVICE_ID

The flash images live in /usr/share/mpss/flash/*smc; Compare the version listed there with that returned by micflash above. If the version in /usr/... is newer, a falsh is required:

Check device status.

• micctrl -s

If not "ready" make it ready

• micctrl -rw

On Mics with C0 hw stepping version do

• /usr/bin/micflash -update -device [DEVICE_ID | all]

For older steppings,

• /usr/bin/micflas -update -device all -smcbootloader

Now the host must be rebooted.

Step 6 - Set SSH keys

First make sure ssh keys exist on the host. If not,

• ssh-keygen -t rsa

When they are ready propagate them to the MIC filesystems

• micctrl --sshkeys=root --dir=/root/.ssh DEVICE_ID

Step 7 - User configuration

To dump everything and reset to default:

• micctrl --cleanconfig
• micctrl --resetdefaults

NFS configuration:

• micctrl --addnfs=server:/dir/ectory --dir=/mnt/point
• micctrl --addnfs=cerberus.local:/home/users --dir=/home/users

Group add: micctrl --groupadd=livetau --gid=1003 DEVICE_ID
