Usage Guidelines

The sub-function is enabled by default and restored to the default setting after disk arrays are restarted, powered off, or powered on, or controllers are reset. To modify the file system sub-function status, you need to specify a controller (only the status of the working controller can be modified) and the modification only takes effect on the specified controller. For example, if the sub-function is disabled on working controller A in a filesystem and then the working controller is switched to controller B, the sub-function will be enabled. After the working controller is switched back to controller A, the sub-function will be disabled.


Enable or disable the sub-function of a file system.

developer:/>change file_system switch file_system_id=3 controller=0B subfunction=bonuscache switch=on
