- Glossary of terms
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 such adjustments manually.
Enter date and time settings manually
1. Perform one of the following to access the Date and Time options:
● In the Home topic, select Action > System Settings.
● In the System topic, select Action > System Settings.
● In the banner, click the System Date/Time Bar panel and select Set Date and Time.
● In the Welcome panel, select System Settings > Date and Time.
2. If checked, clear the Network Time Protocol (NTP) check box.
3. To set the Date value, enter the current date in the format YYYY-MM-DD.
4. To set the Time value, enter two-digit values for the hour and minutes and select either AM, PM, or 24H (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 to save your changes. Otherwise, click Cancel.
Obtain the date and time from an NTP server
1. Perform one of the following to access the Date and Time options:
● In the Home topic, select Action > System Settings.
● In the System topic, select Action > System Settings.
● In the banner, click the System Date/Time Bar panel and select Set Date and Time.
● In the Welcome panel, select System Settings > Date and Time.
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 and 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.
A confirmation panel appears.
6. Click OK to save your changes. Otherwise, click Cancel.
Managing users
The system provides three default users. Nine more users can be created.
The default users are “standard users,” which can access one or more of the following management interfaces: PowerVault
Manager, CLI, SMI-S, or FTP and SFTP. You can also create SNMPv3 users, which can either access the Management
Information Base (MIB) or receive trap notifications. SNMPv3 users support SNMPv3 security features, such as authentication
