pping is a utility used to ping a list of nodes in parallel. pping will return an unsorted list of nodes with a ping or noping status. 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.
-i | --interface 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.
-f | --use_fping
Use fping instead of nmap
-h | --help
Show usage information.
-v | --version
Display the installed version of xCAT.
