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.
