User and group quotas do not apply to the root user or to the Windows Administrator account; tree quotas, however, do apply even to root and the Windows Administrator account.

Data OnTap can simultaneously serve NAS and SAN protocols. CIFS, NFS, and FC protocol are examples of NAS and SAN protocols respectively.

Data OnTap 7.1 or later does not support DAFS.

DFS provides location transparency and redundancy by allowing shares in multiple different locations to be logically grouped under one folder, or DFS root. While practically a CIFS server shared by a Data OnTap filer can be a DFS target, DFS namespaces can only be hosted on Windows systems.

cp_from_log_full (log full) - the current NVRAM bank is full and the system switches to the other one and starts writing this to disk. Very heavy write activity.

cp_from_cp (aka Back to Back) - filer is overloaded. The write traffic is coming in faster than it can be written and the filer is running out of NVRAM capacity in one bank before the data in the other bank can be written.

cp_from_busy is not a real cp type

cp_from_timer - 10 seconds since the last CP – it means the system is pretty idle write-wise.

In order to test or effect a Disaster Recovery operation, you must restrict access to the disaster site node to prevent the node from resuming service. If you do not, you risk the possibility of data corruption.

Access to the disaster site note can be restricted in the following ways:

Turn off the power to the disaster site node Use "manual fencing" (Disconnect VI interconnects and fiber channel cables; either physically or through configuration changes on the fabric switches.)

Isolating the failed node from the surviving node could still lead to the possibility of a split brain, so this is not a correct answer.
