volts contains up to 3 digits after the
decimal point.
Revised command
omconfig chassis volts index=3
minwarnthresh=3.300
When you type the revised command with three decimal points, you receive another error message:
Table 3. Error messages for commands with three decimals
Message
Error! This voltage probe min warning
threshold must be between 11.400 and 12.480.
Revised command
omconfig chassis volts index=3
minwarnthresh=11.500
Message
Voltage probe warning threshold(s) set
successfully.
Scripting And Comparing Using CLI
The Server Administrator CLI allows administrators to write batch programs for the operating system. For an enterprise with many
systems, an administrator could write a configuration script that specifies the warning thresholds for each major component of a
system and also specifies a set of actions that the administrator wants each system to take in case of a warning or failure event. In
most critical cases, the administrator could write a script so that the system shuts down to prevent damage. The administrator
could then distribute and execute the script to many managed systems at the same time. Such a scenario facilitates configuring any
number of new systems acquired by a company and makes implementation of new system administration policies easier across
many existing systems that require re-configuration.
A similar scenario is used to populate a large number of newly acquired systems with detailed asset information. Much of the
information are the same, such as the manufacturer or lessor of the system, whether support for the system is outsourced, name of
the company providing insurance for the system, method of depreciation, and so on. Any variable that is common to all systems is
scripted, sent to all managed systems, and executed. Asset information that is unique to a system is scripted as a group and sent to
that managed node for execution. For example, a script could specify values for all unique variables such as the owner, primary user
phone number, asset tag, and so on. Scripts to populate unique values would set all unique variables at once rather than one by one
through the system's command line.
In many cases, the CLI allows a user with a very well-defined task in mind to retrieve information about the system rapidly. If a user
wants to review a comprehensive summary of all system components and save that summary information to a file for comparison
with later system states, the CLI is ideal.
Using CLI commands, administrators can write batch programs or scripts to execute at specific times. When these programs are
executed, they can capture reports on components of interest, such as fan RPMs during periods of highest system usage compared
with the same measurements at times of lowest system usage. Command results are routed to a file for later analysis. Reports can
help administrators gain information that are used to adjust usage patterns, to justify purchasing new system resources, or to focus
on the health of a problem component.
Command syntax overview
Commands vary in complexity. The simplest command has only command level 1. The omhelp command is a simple command. When
you type omhelp, a list of the main CLI commands is displayed.
The next level of complexity includes commands that contain command levels 1 and 2. All of the about commands are examples of
command level 2 complexity. The omconfig about and omreport about commands display a very brief summary. The summary
shows version information for the systems management software installed on the system; for example, Server Administrator 1.x.
