Complete the following steps to change the date and time on the storage system controller.
CAUTION:
- If you change the system date and time when the currently set date and time is after the real time, the configuration information might not be backed up. To prevent this from happening, move the existing backup file to another folder and then change the system date and time.
- The date and time cannot be changed while a different user is accessing the storage system.
- If you use the SVP, make sure to also update the system date and time on the SVP.
- To use the NTP server, make sure to use the port number 123 for communications between the storage system and the NTP server. Therefore, configure the network settings between the storage system and the NTP server so that the communications using the port number 123 are established.
- If you specify the IP address of the NTP server in IPv6 address format, do not use the following IP addresses:
- Invalid value: [::]
- Loopback address: [::1]
- Multicast address: [FF00:: - FDFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF]
- IPv4-mapped IPv6 address: [::FFFF:(IPv4)]
- Link-local address: [FE80::]
- Global unicast address: [2001::]
- Global unicast address: [2002::]
- If the time setting cannot be performed by using the NTP server, take actions by referring to Other errors.
- You must have the Storage Administrator (View & Modify) role to perform this task.
