Synchronizing local time using Network Time Protocol
You can synchronize the local time of the principal or primary FCS switch to a maximum of eight
external NTP servers. To keep the time in your SAN current, HP recommends that the principal or
primary FCS switch has its time synchronized with at least one external NTP server. The other switches
in the fabric set their time automatically from the principal or primary FCS switch.
All switches in the fabric maintain the current clock server value in nonvolatile memory. By default,
this value is the local clock server <LOCL> 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.
