Product and Software: This article applies to all Aruba controllers and ArubaOS versions.

 

Immediate shutdown or resetting the controller may cause problems for the processes that run in the background. The flash that is used in the controller stores a large amount of information. To speed up the process, however, during runtime, some of this information is copied into RAM.

 

In general, you must power down controllers and conditions permit, power down gracefully by using the 'halt' command rather than just unplugging the power.
