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

  1. Display the discovered nodes when sequential discovery is running:
nodediscoverls

Output is similar to:

UUID                                    NODE                METHOD         MTM       SERIAL

51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB3    distest2            sequential     786310X   1052EF3
  1. Display the nodes that were in the discovery pool, but for which xCAT has not yet received a discovery request:
nodediscoverls -t undef

Output is similar to:

UUID                                    NODE                METHOD         MTM       SERIAL
51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB0    undef               undef          786310X   1052EF0
51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB1    undef               undef          786310X   1052EF1
  1. Display all the discovered nodes:
nodediscoverls -t all

Output is similar to:

UUID                                    NODE                METHOD         MTM       SERIAL
51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB0    undef               undef          786310X   1052EF0
51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB1    undef               undef          786310X   1052EF1
51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB2    distest1            sequential     786310X   1052EF2
51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB3    distest2            sequential     786310X   1052EF3
  1. Display the discovered node whose uuid is 51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB2, with detailed information:
nodediscoverls -u 51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB2 -l
