The icon indicates that the panel has a menu. Click anywhere in the panel to display a menu to change date and time settings.
Changing date and time settings
You can change the storage system date and time, which appear in the date/time panel in the banner. It is important to set the
date and time so that entries in system logs and notifications have correct time stamps.
You can set the date and time manually or configure the system to use NTP to obtain them from a network-attached server.
When NTP is enabled, and if an NTP server is available, the system time and date can be obtained from the NTP server. This
allows multiple storage devices, hosts, log files, and so forth to be synchronized. If NTP is enabled but no NTP server is present,
the date and time are maintained as if NTP was not enabled.
NTP server time is provided in the UTC time scale, which provides several options:
● To synchronize the times and logs between storage devices installed in multiple time zones, set all the storage devices to use
UTC.
● To use the local time for a storage device, set its time zone offset.
● If a time server can provide local time rather than UTC, configure the storage devices to use that time server, with no
further time adjustment.
Whether NTP is enabled or disabled, the storage system does not automatically make time adjustments for Daylight Saving
Time. You must make that adjustment manually.
NOTE: If you change the time zone of the secondary system in a replication set whose primary and secondary systems
are in different time zones, you must restart the system to enable management interfaces to show proper time values for
replication operations.
Use manual date and time settings
Perform the following steps to manually set the date and time settings:
1. In the banner, click the date/time panel and select Set Date and Time.
The Date and Time panel opens.
2. Clear the Network Time Protocol (NTP) checkbox.
3. To set the Date value, type the current date in the format YYYY-MM-DD.
4. To set the Time value, type the current time in the format HH:MM.
NOTE: The system time uses a 24-hour clock.
5. Perform one of the following:
● To save your settings and continue configuring your system, click Apply.
● To save your settings and close the panel, click Apply and Close.
A confirmation panel appears.
6. Click OK.
Obtain the date and time from an NTP server
1. In the banner, click the date/time panel and select Set Date and Time.
The Set Date and Time panel opens.
2. Select the Network Time Protocol (NTP) check box.
3. Perform one of the following:
● To have the system retrieve time values from a specific NTP server, enter its IP address in the NTP Server Address field.
● To have the system listen for time messages sent by an NTP server in broadcast mode, clear the NTP Server Address
field.
4. In the NTP Time Zone Offset field, enter the time zone as an offset in hours, and optionally, minutes, from UTC. For
example, the Pacific Time Zone offset is -8 during Pacific Standard Time or -7 during Pacific Daylight Time. The offset for
Bangalore, India is +5:30.
5. Perform one of the following:
● To save your settings and continue configuring your system, click Apply.
● To save your settings and close the panel, click Apply and Close.
