acl set

Modifies the Access Control List (ACL) for a cluster, volume, or security policy.

The acl set command specifies the Access Control List (ACL) for a cluster or volume. Any previous permissions are overwritten by the new values, and any permissions omitted are removed. To use the acl set command, you must have administrative (a) permissions on the volume and cluster for which you are running the command. The permissions are specified as a comma-separated list of permission codes. See acl. You must specify either a user or a group. When the type is volume, you must specify a volume name using the name parameter.

The acl set command removes any previous ACL values. To preserve some of the permissions, you should either use the acl edit command instead of acl set, or use acl show to list the values before overwriting them.
