=head1 DESCRIPTION
|
||
|
|
|
||
|
|
The B<snmove> command moves the nodes from one service nodes to another. It assumes that both service nodes can reach the nodes in terms of network. Both are configured as service nodes and listed in the B<noderes.servicenode> for the nodes. The source service node is the first in the list and also in B<noderes.xcatmaster>. This command will move the desination service node I<sn2> to the first in the list for B<noderes.servicenode> and also change <noderes.master> to match I<sn2>. It'll also change the services so that TFTP, NFS, serial console and DHCP will use the new server for the nodes. If -i is specified, the nodes themselves will be untouched. Otherwise, syslog and NTP will be changed to use the new service node as the master. The user can run other postscripts using updatenode command after this command is done to setup other applications such as monitoring. The destination service node <sn2> has to be up and running, but the source service node does not have to.

|
=item B<-S|--sourcen>
|
||
|
|
|
||
|
|
Specifies the hostname of the source service node adapter facing the nodes.

|
|
||
|
|
=item B<-d|--dest>
|
||
|
|
|
||
|
|
Specifies the hostname of the destination service node adapter facing the management node. It can be found in the B<servicenode> table.
