=head1 NAME

B<swapnodes> - swap the location info in the db between 2 nodes. If swapping within a cec, it will assign the IO adapters that were assigned to the defective node to the available node. 

=head1 SYNOPSIS

B<swapnodes> [B<-h>| B<--help>]

B<swapnodes> B<-c> I<current_node> B<-f> I<fip_node> [B<-o>]

=head1 DESCRIPTION

This command is only for P7 IH using Direct FSP Management. Without B<-o> option, it's used to swap the location info in the db between 2 nodes. With B<-o> option, it's used to move the I<current_node> definition to I<fip_node> (the 2nd octant), not move the I<fip_node> definition to the 1st octant. If the two nodes are in a cec, it will assign the IO adapters that were assigned to the defective node to the available node. Originally, the I<current_node> is a defective non-compute node, and I<fip_node> is a avaible compute node. After the swapping, the I<current_node> will be a available node.

=head1 OPTIONS

=over 5

=item B<-h|--help>

Display usage message.

=item B<-c>

I<current_node> -- the defective non-compute node.

=item B<-f>

I<fip_node> -- a compute node which will be swapped as the non-compute node.

=item B<-o>

one way. Move the I<current_node> definition to I<fip_node> (the 2nd octant), and not move the I<fip_node> definition to the 1st octant.

=head1 RETURN VALUE

0 The command completed successfully.

1 An error has occurred.

=head1 EXAMPLES

=over 3

=item 1.

To swap the service node attributes and IO assignments between sn1 and compute2 which are in the same cec:

 swapnodes -c sn1 -f compute2
