|
|
B<pping> [B<-i>|B<--interface> I<interfaces>] [B<-f>|B<--use_fping>] I<noderange>

=head1 DESCRIPTION
|
|
|
|
B<pping> is a utility used to ping a list of nodes in parallel.
|
|
B<pping> will return an unsorted list of nodes with a ping or noping status.
|
|
B<pping> front-ends nmap or fping if available.
|
|
|
|
This command does not support the xcatd client/server communication. It must be run on the management node.

=head1 OPTIONS
|
|
|
|
=over 10
|
|
|
|
=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<-f>|B<--use_fping>
|
|
|
|
Use fping instead of nmap
|
|
|
|
=item B<-h>|B<--help>
|
|
|
|
Show usage information.
|
|
|
|
=item B<-v>|B<--version>
|
|
|
|
Display the installed version of xCAT.
