Modify Date and Time

Overview

This function specifies the date/time and time zone (storage system location) of the internal clock in the storage system.

The clock is used for checking the internal log of the storage system and in the Eco-mode, etc. The time zone setting is used for the Remote Support function.

This function is used when moving the storage system to a new installation site, and/or changing the storage system date/time.

It is possible to setup the NTP server to automatically set the time. If the NTP server cannot be used, resetting the time once a month is recommended.

Caution

  • When the network environment is set to the factory default, the NTP function cannot be used. Perform the [Setup Network Environment] function.

  • When using Eco-mode, make sure to set the date/time correctly. If the date/time of the storage system is wrong, processes for stopping and starting the disk motor cannot be performed in accordance with the Eco-mode schedule.

  • The [Modify Date and Time] function cannot be used while time synchronization with the NTP server is being performed.

Note

  • When using the NTP server, the time modification method is the step mode (modify immediately).

  • When using the NTP server, the storage system is synchronized with the NTP server every three hours.
