nodediscoverls.1
NAME
nodediscoverls - List the discovered nodes
SYNOPSIS
nodediscoverls [-t seq | profile | switch | blade | manual | undef | all] [-l]
nodediscoverls [-u uuid] [-l]
nodediscoverls [-h | --help | -v | --version]
DESCRIPTION
The nodediscoverls command lists nodes that have recently been discovered. If discovery is currently in progress (i.e. nodediscoverstart has been run, but nodediscoverstop has not been), then nodediscoverls will list the nodes that have been discovered so far in this session. If discovery is not currently in progress, nodediscoverls will list all of the nodes that were discovered in the last discovery session.
You can use the -t option to limit the output to just the nodes that were discovered in a particular method of discovery.
OPTIONS
-t seq|profile|switch|blade|manual|undef|all
Display the nodes that have been discovered by the specified discovery method:
* seq - Sequential discovery (started via nodediscoverstart noderange=<noderange> …).
* profile - Profile discovery (started via nodediscoverstart networkprofile=<network-profile> …).
* switch - Switch-based discovery (used when the switch and switches tables are filled in).
* blade - Blade discovery (used for IBM Flex blades).
* manual - Manually discovery (used when defining node by nodediscoverdef command).
* undef - Display the nodes that were in the discovery pool, but for which xCAT has not yet received a discovery request.
* all - All discovered nodes.
-l
Display more detailed information about the discovered nodes.
-u uuid
Display the discovered node that has this uuid.
-h|--help
Display usage message.
-v|--version
Command version.
RETURN VALUE
0 The command completed successfully.
1 An error has occurred.
EXAMPLES
Display the discovered nodes when sequential discovery is running:

Display the nodes that were in the discovery pool, but for which xCAT has not yet received a discovery request:
nodediscoverls -t undefOutput is similar to:

Display all the discovered nodes:
nodediscoverls -t allOutput is similar to:

Display the discovered node whose uuid is 51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB2, with detailed information:
