mkcosi Command

Purpose

Makes a Common Operating System Image (COSI) for use with thin servers.

Syntax

mkcosi -s Source [-l Location] [-S Server] [-v] COSI

Description

The mkcosi command creates a Common Operating System Image (COSI). A COSI is a repository that contains all the necessary software to bring a thin server up to a functional state. The mkcosi command takes a source (-s Source) containing installable images and attempts to install those software images into a specific location (-l Location). If the -S Server is specified, the COSI image is stored on that particular server. The result is an OS image that can be used by thin servers as its boot image and operating system.

This command is dependent upon the bos.sysmgt.nim.master fileset being present on the system. When this command is executed for the first time, the machine executing the command will be configured as a NIM master. The mkcosi command uses the nim_master_setup command to configure the machine as a NIM master. The -S parameter must point to a machine that is managed by the caller of the mkcosi command.
