Access Control Expression (ACE)

NOTE An ACE (up to 64KB in length) is a combination of users, groups, and/or roles for whom access (to volume data) is defined using boolean expressions and sub expressions within single quotes. When you pass in an access type that has already been set, the new value replaces the existing value for that access type. There is no change to access types that are not passed in with the command, whether or not they were set. For more information, see Managing Access Control Expressions.
