To reload the current settings from the filer, click the Reload Settings button. To view the changes that you made, click the View Changes button. After you make a change, click the Save Changes button to save the changes to the filer.

NDMP Enabled

Enables Network Data Management Protocol (NDMP) support on the filer. With NDMP, you can use third-party backup management programs that support NDMP Version 1 or Version 2 to back up the filer. NDMP can back up the filer to these devices:

• Tape drive or stacker (library) attached to the filer
• Tape drive or stacker (library) attached to the workstation that runs the backup program
• Tape drive or stacker (library) attached to a workstation or filer on your network

Save Core Files

Saves two core files from a filer crash in the /etc/crash directory:

• The core.n-small file contains everything except the file system buffers.
• The core.n file includes more information that might be essential for determining the cause of the crash; it is often necessary for investigating problems involving the file system.

The n in the file name of the core file is a number. Core files are created only during the first boot after a system crash.

Timed Enabled

Yes causes a time daemon (timed) to run on the filer and synchronize time with a time server.

No causes no time synchronization with a time server.

Timed Log Enabled

Yes logs to the console time changes initiated by the timed daemon.

No causes no logging.

Timed Max Skew

This field sets the maximum allowable discrepancy between filer time and server time. If there is a large discrepancy, it probably means that enough is wrong somewhere that the filer time should not be synchronized with the server time, no time synchronization takes place, and a message to that effect is sent to the console. The value is an integer followed by one of the following letters:

• s for seconds
• m for minutes
• h for hours

The default is 30m, which specifies 30 minutes.

Timed Protocol

Select  one of the following  protocols:

• rdate for the protocol used by the rdate command, which synchronizes the filer’s time with the time on another host with an accuracy of one second.
• ntp for SNTP (Simple NetworkTime Protocol), which synchronizes the filer’s time with the time on a time server to a theoretical maximum accuracy of one nanosecond; actual accuracy depends on the accuracy of the time server and network delays.

Timed Schedule

Schedules when to synchronize the time with a time server. The value can be one of the following:

hourly to synchronize hourly

multihourly to synchronize every six hours

daily to synchronize every day at midnight

a number followed by m to specify an interval of minutes or h to specify an interval of hours

To avoid overburdening the time server, the filer randomly selects the exact time of the synchronization within a 20-minute window of the specified schedule.

Timed Servers

Type into this field up to five servers, separated by commas, in order of contact priority. You can use  host names or IP addresses. The filer goes down the list until it finds a server that responds, then uses the time from that server. It starts with the first server in the list each time. An example list of three time servers is as follows:

sundial, sundial.netapp.com, 10.152.8.12

You can get a list of NTP (Network Time Protocol) time servers, which SNTP can use, from http://www.eecis.udel.edu/~mills/ntp/servers.htm.
