An access control LUN is presented to ONTAP

ONTAP does not support access control array LUNs. The storage errors show output alerts you if an access control LUN is being presented.

Storage errors show message

NAME (UID): This array LUN is an access control LUN. It is not supported and should be masked off or disabled. 

Explanation

ONTAP supports only storage array LUNs. When an array LUN, for example, an E-Series access control LUN is presented to ONTAP, the storage array config show output looks normal; it shows the access control LUN in a LUN group, as the following example shows. The warning message at the bottom of the screen indicates the problem. You need to run storage errors show to find out that the problem is that an access control LUN was presented and which LUN it is.

Troubleshooting and problem resolution

  1. On the storage array, mask off the access control LUN.
  2. In ONTAP, run storage errors show again to confirm that the access control LUN is no longer being presented to ONTAP.
