ACS robotic test utility
The acstest utility lets you verify ACS communications and provides a remote system administrative interface to an ACS robot. It can also be used to query, enter, eject, mount, unload, and dismount volumes. In addition, acstest lets you define, delete, and populate ACS library software scratch pools.
While acsd services requests, do not use acstest. Communication problems may occur if acsd and acstest process ACS requests at the same time.
