Use the Setting Cluster Time panel in the SAN Volume Controller Console to
view or change the current cluster settings for the date, time, and
time zone. You can also configure time settings by using a Network
Time Protocol (NTP) server, which can be used to set the cluster time
from an outside source. When you use the NTP server, you ensure that
the time settings are consistent across different clusters.
Attributes
The
following attributes are displayed in the table:
- Cluster date
- Displays the existing setting for the cluster date.
- Cluster time
- Displays the existing setting for the cluster time.
- Cluster time zone
- Displays the existing setting for the cluster time zone.
- NTP server
- Displays the IP address of the NTP server that is used to manage
time settings on the cluster.
Fields
You
can update the following fields:
Set NTP Server
Use
the Set NTP Server field to specify the IP address of the NTP server.
The system time of the configuration node adjusts to the time values
that are obtained from the NTP server and modified according to the
cluster time zone. The time on other nodes in the cluster is updated
based on the time on the configuration node. Enter the corresponding
IP address for the NTP server. The
SAN Volume Controller Console supports
both IPv4 and IPv6 address formats.
If
you are using a remote server to authenticate user to the cluster,
you can use a NTP server to ensure consistent time settings between
the cluster and the remote authentication service.Note: The
options that are displayed are based on the current IP address format
that is configured for the cluster.
- IPv4
- Enter the IPv4 address for the NTP server.
- IPv6
- Enter the IPv6 address for the NTP server.
- Dual Stack (IPv4 and IPv6)
- Use the radio button to select whether the NTP server IP address
you are providing is an IPv4 address or an IPv6 address. Then enter
the IP address in the appropriate place.
Modify Time
Use the Modify Time
settings to change the system time on the configuration node. The
configuration node automatically sends all date and time updates to
all nodes in the cluster to ensure that all nodes are synchronized.
If you selected to use an NTP server to manage time settings on your
cluster, these options are disabled.
- Date (01 - 31)
- Enter the day of the month to use for the cluster date settings.
- Month (01 - 12)
- Enter the number that corresponds with the month to use for the
cluster date settings.
- Year (20xx)
- Enter the current calendar year to use for the cluster date settings.
- Hours (00 - 23)
- Enter the time in hours to use for the cluster time settings.
- Minutes (00 - 59)
- Enter the minutes to use for the cluster time settings.
Modify Time Zone
Use the Modify Time
Zone settings to change the time zone on the configuration node. The
configuration node automatically sends all time zone updates to all
nodes in the cluster to ensure that all nodes are synchronized.
- Time Zone
- Select the appropriate time zone for the cluster.
Actions
The
following actions are available:
- Set NTP Server
- Click this button to set the specified NTP server as the method
of managing time on the cluster and its nodes.
- Delete NTP Server
- Click this button to delete the current settings for the NTP server.
This action displays only when the NTP server has been set.
- Update Cluster Time
- Click this button to update applicable time and date settings
with the values you have entered.
- Update Time Zone
- Click this button to update the cluster time zone setting to the
value you have selected.
