################ nodediscoverls.1 ################ .. highlight:: perl **** 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= ...). \* \ **profile**\ - Profile discovery (started via nodediscoverstart networkprofile= ...). \* \ **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: .. code-block:: perl nodediscoverls Output is similar to: .. code-block:: perl UUID NODE METHOD MTM SERIAL 51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB2 distest1 sequential 786310X 1052EF2 51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB3 distest2 sequential 786310X 1052EF3 2. Display the nodes that were in the discovery pool, but for which xCAT has not yet received a discovery request: .. code-block:: perl nodediscoverls -t undef Output is similar to: .. code-block:: perl UUID NODE METHOD MTM SERIAL 51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB0 undef undef 786310X 1052EF0 51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB1 undef undef 786310X 1052EF1 3. Display all the discovered nodes: .. code-block:: perl nodediscoverls -t all Output is similar to: .. code-block:: perl 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 4. Display the discovered node whose uuid is \ **51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB2**\ , with detailed information: .. code-block:: perl nodediscoverls -u 51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB2 -l Output is similar to: .. code-block:: perl Object uuid: 51E5F2D7-0D59-11E2-A7BC-3440B5BEDBB2 node=distest1 method=sequential discoverytime=03-31-2013 17:05:12 arch=x86_64 cpucount=32 cputype=Intel(R) Xeon(R) CPU E5-2690 0 @ 2.90GHz memory=198460852 mtm=786310X serial=1052EF2 nicdriver=eth0!be2net,eth1!be2net nicipv4=eth0!10.0.0.212/8 nichwaddr=eth0!34:40:B5:BE:DB:B0,eth1!34:40:B5:BE:DB:B4 nicpci=eth0!0000:0c:00.0,eth1!0000:0c:00.1 nicloc=eth0!Onboard Ethernet 1,eth1!Onboard Ethernet 2 niconboard=eth0!1,eth1!2 nicfirm=eth0!ServerEngines BE3 Controller,eth1!ServerEngines BE3 Controller switchname=eth0!c909f06sw01 switchaddr=eth0!192.168.70.120 switchdesc=eth0!IBM Flex System Fabric EN4093 10Gb Scalable Switch, flash image: version 7.2.6, boot image: version 7.2.6 switchport=eth0!INTA2 ******** SEE ALSO ******** nodediscoverstart(1)|nodediscoverstart.1, nodediscoverstatus(1)|nodediscoverstatus.1, nodediscoverstop(1)|nodediscoverstop.1, nodediscoverdef(1)|nodediscoverdef.1
