Synchronizing the system time

The timed daemon enables you to keep the system time for your storage system automatically synchronized with a time server. Using this feature is advised, because problems can occur when the storage system clock is inaccurate.

About this task

To keep your storage system time synchronized automatically, you need the name of at least one time server. For best results, supply the name of more than one time server in case one becomes unavailable.

You use the Network Time Protocol (NTP) protocol for time synchronization. You can get a list of public NTP time servers from the NTP Public Services web at support.ntp.org.

The timed daemon operates independently on each node in an HA pair.

Steps

  1. If the current time for the storage system is not fairly close to the actual time, use the date command to set the system time to the correct time.
  2. Set the appropriate timed options by using the options command at the storage system prompt.

    You must ensure that the timed.proto option is set to ntp, and set the timed.servers option to at least one valid time server.

    You must also ensure that the timed.enable option is set to on.

    For more information about the timed options, see the na_options(1) man page.
