Chapter 13

Using the samu Operator Utility

This chapter describes how to use the samu command to control the devices configured within your environment. Many samu displays are useful only for sites using the storage and archive management mechanism. If you are using samu in a Sun QFS-only environment, these displays do not apply to you.

You can also use the samcmd command to perform many of the same operations. For more information, see samcmd(1M) in Sun QFS and Sun Storage Archive Manager 5.3 Reference Manual.
