Caution about using the ACLX LUN

On VMAX arrays, the ACLX (Access Control Logix) LUN is created during initialization if the customer requests using ACLX. The ACLX LUN is not a storage LUN so it should not be mapped to Data ONTAP.

If the ACLX LUN is mapped to a V-Series system, Data ONTAP logs a message that the ACLX LUN is less than the minimum size required, and it marks the LUN as failed. The V-Series system continues to function normally after logging this error message, but it cannot use the LUN.

An ACLX LUN should be unmapped from the front-end director ports for a V-Series system .
