Limit the Operation of Connectivity Control Commands

In some cases, you may only want to see what VARY operations an SOF command would perform, without actually executing the operations. For that purpose, SOF connectivity control commands support the NOEXEC parameter, which prohibits execution of all operations.

SOF connectivity control commands also support the following parameters to control or limit specific aspects of their operation:

• NOVARY parameter, which prevents all VARY ONLINE processing for both paths and devices.
• BACKOUT parameter, which reverses all VARY processing in case of failure.
• FORCE parameter, which ignores any VARY failures.
• TIMEOUT parameter, which limits the amount of time allowed for the command to fully complete execution.
• MAXDEVICES parameter, which limits the number of devices that may be affected by the command.

For detailed descriptions of these parameters, see the DEFAULTS command.
