|
|
|
|
I<switchdiscover [-h|--help]>
|
|
|
|
I<switchdiscover [-v|--version]>

=head1 DESCRIPTION
|
|
|
|
I<makentp> command sets up the NTP server on the xCAT management node and the service node.
|
|
|
|
By default, it sets up the NTP server for xCAT management node. It gets the site table attribute I<extntpservers> and have the local NTP server sync with the external ntp servers defined by <site.extntpservers>. If -a flag is specified, the command also works for all the service nodes that have I<servicenode.ntpserver> set. The NTP server on the service node will sync with the management node.
|
|
|
|
This command is also called by xcatd when it starts on the xCAT management node and the service nodes.
|
|
|
|
To setup NTP client on other nodes such as compute nodes, please add B<setupntp> postscript to the I<postscripts> table and run I<updatenode node -P setupntp>. The setupntp postscripts honors I<site.ntpservers> attribute for NTP servers. If the value of I<site.ntpservers> is "<xcatmaster>" then the management node or the service node that serves the node will be the NTP server.
