Set RAID controller NTP settings
Description
The set controller NTPServers command sets the NTP settings for the controller so the RAID
controller can automatically synchronize the clocks with an external host using SNTP (Simple Network
Time Protocol). When this feature is enabled, the RAID controller periodically queries the configured NTP
server, then uses the results to update its internal time-of-day clock. If only one RAID controller has NTP
enabled, the alternate RAID controller will periodically synchronize its clock with the RAID controller that
has NTP enabled. If neither RAID controller has NTP enabled, the RAID controllers periodically
synchronize their clocks with each other.
Before you begin
NOTE: This command is RAID controller-specific. It is not necessary to configure NTP on both RAID
controllers; however, doing so improves the array's ability to stay synchronized during hardware or
communication failures.
CAUTION: If you configure NTP using a fully qualified domain name, you must also configure
DNS on those RAID controller(s) for the operation to succeed.
Syntax
set controller[0|1] NTPServers=(disabled|auto|(Address1 [Address2]))
Parameters
Table 19. RAID Controller NTP settings parameters
Parameter Description
Controller
The RAID controller for which you want to change
the NTP settings. Valid controller identifiers are 0
or 1.
NTPServers
This parameter configures the NTP servers for the
RAID controller.
• Specify disabled to turn off NTP support.
• Specify auto to use the NTP server addresses
provided by a DHCP server.
NOTE: This option should only be used if
at least one management port on the RAID
controller is set to get interface parameters
using DHCP, and at least one NTP server is
configured on the DHCP server.
• Otherwise, specify a whitespace separated list
of one or two NTP servers. The addresses may
be a domain name, IPv4 address, or IPv6
address. If specifying more than one address,
the address types do not need to match. If
more than one address is specified, they will be
used in the order they are specified (first is
primary, second is backup).
