154 Using and Configuring Virtual Media
VM-CLI Operating System Shell Options
The following operating system features can be used in the VM-CLI command line:
• stderr/stdout redirection — Redirects any printed utility output to a file.
For example, using 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). As a result, stdin redirection is not required.
• Background execution — By default, the VM-CLI utility runs in the foreground. Use the operating
system's command shell features 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
0 = No error
1 = Unable to connect
2 = VM-CLI command line error
3 = RAC firmware connection dropped
English-only text messages are also issued to standard error output whenever errors are encountered.

Question Answer
Sometimes, I notice my Virtual Media client
connection drop. Why?
When a network time-out occurs, the DRAC 5 firmware drops
the connection, disconnecting the link between the server and
the Virtual Drive. To reconnect to the Virtual Drive, use the
Virtual Media feature.
