=head1 NAME
|
|
|
|
B<ppping> - parallel ping from nodes to other nodes in the cluster.
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<ppping> [B<-i>|B<--interface> I<interfaces>] [B<-d>|B<--debug>] [B<-V>|B<--verbose>] [B<-q>|B<--quiet>] [B<-s>|B<--serial>] I<noderange>
|
|
|
|
B<ppping> [B<-h>|B<--help>]
|
|
|
|
B<pping> {B<-v>|B<--version>}
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
B<ppping> is a utility used to test the connectivity between nodes in the noderange using ping.
|
|
By default, B<ppping> will return an unsorted list of the node pairs that are not able to ping each other, or a message that all nodes are pingable.
|
|
More or less output can be controlled by the -V and -q options.
|
|
B<ppping> front-ends B<pping> and B<xdsh>.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 10
|
|
|
|
=item B<-s>
|
|
|
|
Ping serially instead of in parallel.
|
|
|
|
=item B<-i>|B<--interface> I<interfaces>
|
|
|
|
A comma separated list of network interface names that should be pinged instead of the interface represented by the nodename/hostname.
|
|
The following name resolution convention is assumed: an interface is reachable by the hostname <nodename>-<interface>. For example,
|
|
the ib2 interface on node3 has a hostname of node3-ib2.
|
|
|
|
If more than one interface is specified, each interface will be combined with the nodenames as described above and will be pinged in turn.
|
|
|
|
=item B<-V>|B<--verbose>
|
|
|
|
Display verbose output. The result of every ping attempt from every node will be displayed. Without this option, just a summary
|
|
of the successful pings are displayed, along with all of the unsuccessful pings.
|
|
|
|
=item B<-q>|B<--quiet>
|
|
|
|
Display minimum output: just the unsuccessful pings. This option has the effect that if all pings are successful, nothing is displayed.
|
|
But it also has the performance benefit that each node does not have to send successful ping info back to the management node.
|
|
|
|
=item B<-d>|B<--debug>
|
|
|
|
Print debug information.
|
|
|
|
=item B<-h>|B<--help>
|
|
|
|
Show usage information.
|
|
|
|
=item B<-v>|B<--version>
|
|
|
|
Display the installed version of xCAT.
