IBM Storage Scale administration commands

IBM Storage Scale administration commands are programs and scripts that control the configuration and operation of IBM Storage Scale. They typically begin with the letters mm, like in the mmcrcluster command.

By default, you can issue IBM Storage Scale administration commands from any node in a cluster. If the execution of an administration command requires tasks to be performed on other nodes in the cluster, then the command automatically sends orders to the nodes to perform the tasks.

For this inter-node communication to succeed, one of the following setups is required:

All the nodes in the cluster must be configured to allow passwordless remote shell communications.
IBM Storage Scale sudo wrapper scripts must be configured on all the nodes of the cluster.

For more information about these two setups, see Requirements for administering a GPFS file system.

For descriptions of the commands, see Command reference.
