Configuring the power and console interfaces

There are many existing solutions for power management of cluster nodes. Utilities have been written to interface to many power controllers, and vendors often include their own power management utilities with their products.

Every power utility has a different way of representing the set of nodes on which to operate. Similarly, many different methods can be used to access the serial console of all cluster nodes.

oneSIS provides a generalized wrapper interface that can easily tie into any existing power or console management solution. It serves as a common interface for power and console management across all machines, eliminating the need for an admin to remember the particular command and syntax used for power management and console access on each particular group of machines.

The POWERCMD directive is a way to quickly describe how a particular power management utility works so that the pwr (section 6.7) command can then interface to it. Similarly, the CONSOLECMD directive can quickly describe how to access the remote console of any node, and thereafter the consl (section 6.8) command can be used to access a node's serial console.
