MFU is designed to all a user to update, edit and save the BIOS and IPMI firmware accross multiple nodes through a single command.

Installation

Scmsh must be installed on the host from which you will run the commands.
Each node to be controlled must have the scmsh agent daemon installed on the system (scmnode).

Adding nodes to the scmsh

For each node to be monitored by scmsh a line must be added to the nodes.cfg file on the master node.

The line must contain four bits on information:

Node Name
Node Mac address
Node Ipaddress / Hostname
Port it will use to communicate (default 4422)

compute020=00:25:90:6C:DC:DE,compute020:4422

Running in Interactive Mode

To start MFU in interactive mode, navigate to the install directory and run the command:

./run_scmsh

Running in Scripted Mode

MFU can also be scripted to automate fw updates across a cluster

# Assumes the following are set
export LANG=C
export LD_LIBRARY_PATH=.:$LD_LIBRARY_PATH:/opt/scmsh/lib
export SCMSH_PATH=/opt/scmsh/
export SCMNODE_PATH=/opt/scmnode/

# then run with scmsh <cmd>, for eg
./scmsh  list node
