Indicate how you want to set the system time:
Automatic—Use a time daemon to keep the system time synchronized with a time server. NetApp recommends that you use this feature because problems can occur when the system clock is inaccurate. The time synchronizes the storage system date and time to an accuracy within one second of the date and time of the remote host.
Note: There is currently no Windows 95 or Windows NT counterpart for synchronization. You must have a UNIX workstation that supports remote synchronization on your storage system network.
Manual—Specify the system date and time using the fields presented in the Date/Time wizard.
NetApp strongly recommends that you use a time daemon to update the system time in a cluster configuration. For either method, Data ONTAP always attempts to keep the system time on the two nodes synchronized. One node is the "time master" and the other node is the "time slave." The determination of time master and time slave is automatic and cannot be controlled by administrators. The time slave always attempts to synchronize with the time master using the SNTP protocol over the cluster interconnect. If that attempt fails, the system time update method you choose determines whether the time slave will then try to synchronize directly with a time server.
