Identify the master IOM

To initiate the module replacement process, identify the master IOM connected to the SmartFabric.

To identify the master IOM in the SmartFabric, use the show smartfabric cluster member command. For more information, see show smartfabric cluster member. Run the command from any of the IOMs connected in the SmartFabric. The content displayed varies depending on the switch role.

If the command is run on a member, the system displays only the details of the master IOM. The system displays information such as service tag and IPv6 address of the master. If the command is run in a master, the system displays the details of all the IOMs in the chassis deployment. Log in to the master IOM using the displayed IPv6 address before using the module replacement command. For more information about how to log in to the master IOM from the member, see Log in to the master IOM from the member.

Also you can view the IPv4 address of the master IOM using the show smartfabric cluster command. For more information, see show smartfabric cluster.
