The snapvault subcommands are:

start [ -r ] [ -k n ] [ -t n ] [ -w ] [-p {inet | inet6 unspec}] [ -o options ]

[ -S [primary_filer:]primary_path ] secondary_qtree

modify [ -k n ] [ -t n ] [-p {inet | inet6 | unspec}] [ -o options ] [ -S

primary_filer:primary_path ] sec_ondary_qtree

The -k option sets the maximum speed at which data is transferred in kilobytes per second. It is used to throttle disk, CPU, and network usage. If this option is not set, the filer transmits data as fast as it can. The setting applies to the initial transfer as well as subsequent update transfers from the primary.

Volume SnapMirror Interoperability Matrix.

You can export any file path. Implicitly file paths are filesystem objects. You can export a directory, a qtree, a volume or even a file.

Changes to deduplication in 8.1 7-mode

Starting with Data ONTAP 8.1, you can enable the deduplication feature without adding a license. For

deduplication, no limit is imposed on the supported maximum volume size. The maximum volume size limit is determined by the type of storage system regardless of whether deduplication is enabled.

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.

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.

March, 2011: "With the recent release of Data ONTAP 8.0.1, NetApp now offers full disk encryption to prevent unauthorized access to data at rest."

vol options nosnapdir [on|off]

If this option is on, it disables the visible .snapshot directory that is normally present at client mount points, and turns off access to all other .snapshot directories in the volume. The default setting is off.

https://library.netapp.com/ecmdocs/ECMP1196890/html/man1/na_nfsstat.1.html

nfsstat and sysstat are OnTap commands used for performance information.

sio_ntap_soll is not an OnTap command.

Perfstat is a GUI performance tool, not an OnTap command. Think of PerfMon for Windows to remind you that PerfStat is a Windows tool. Note how many of the ONTAP performance commands end in stat.
