VM-CLI Operating System Shell Options

Features of the operating system shell can be used on the VM-CLI command line:

•stderr/stdout redirection: Redirects any printed output of the utility to a file. For example, the greater-than character (>), followed by a filename, overwrites the specified file with the printed output of the VM-CLI utility.

NOTE: The VM-CLI utility does not read from standard input (stdin), so there is no need to use stdin redirection.

•Background execution: By default, the VM-CLI utility runs in the foreground. Use the operating system’s command shell background character to cause the utility to run in the background. For example, under a Linux operating system, the ampersand character (&) following the command causes the program to be spawned as a new background process.

The latter technique is useful in script programs, as it allows the script to proceed after a new process is started for the VM-CLI command (otherwise, the script would block until the VM-CLI program is terminated). When multiple VM-CLI instances are started in this way, and one or more of the command instances must be manually terminated, use the operating system-specific facilities for listing and terminating processes.

VM-CLI return codes

The VM-CLI return codes are:

•0 = No error

•1 = Unable to connect

•2 = VM-CLI command line error

•3 = RAC firmware connection dropped

Text messages (English-only) are also issued to standard output whenever errors are encountered.
