All switches in the fabric maintain the current clock server value in non-volatile memory. By default, this value is the local clock server of the principal or primary FCS switch. Changes to the clock server value on the principal or primary FCS switch are propagated to all switches in the fabric. For more information on using an NTP server, and IPv6 considerations, see the Fabric OS Administrator's Guide. 1. If you are not already logged into the switch; do so now using the default password, which is password. 2. Enter the tsClockServer command: switch:admin> tsclockserver "" where ntp1 is the IP address or DNS name of the first NTP server, which the switch must be able to access. The second ntp2 is the second NTP server and is optional. The operand "" is optional; by default, this value is LOCL, which uses the local clock of the principal or primary switch as the clock server. The tsClockServer command accepts multiple server addresses in either IPv4, IPv6, or DNS name formats. When multiple NTP server addresses are passed, tsclockserver sets the first obtainable address as the active NTP server. The rest will be stored as backup servers that can take over if the active NTP server fails. The principal or primary FCS switch synchronizes its time with the NTP server every 64 seconds. switch:admin> tsclockserver LOCL switch:admin> tsclockserver "132.163.135.131" switch:admin> tsclockserver 132.163.135.131 switch:admin> The following example shows how to set up more than one NTP server using a DNS name: switch:admin> tsclockserver "10.32.170.1;10.32.170.2;ntp.localdomain.net" Updating Clock Server configuration...done. Updated with the NTP servers Changes to the clock server value on the principal or primary FCS switch are propagated to all switches in the fabric. 20 SAN24B-4 Express Installation, Service, and User Guide
