MFU: Mass Firmware Update

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

Master: scmsh

scmsh must be installed on the host from which you will run the commands.

Nodes: scmshnode

Each node must have the scmsh agent daemon installed on the system.

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)
