xCAT probe
==========
To help identify some of the common issues with xCAT, a new tool suite is now available **xCAT probe**.
You can use ``xcatprobe -l`` to list all valid subcommands, output will be as below ::
# xcatprobe -l
osdeploy Probe operating system provision process. Supports two modes - 'Realtime monitor' and 'Replay history'.
xcatmn After xcat installation, use this command to check if xcat has been installed correctly and is
ready for use. Before using this command, install 'tftp', 'nslookup' and 'wget' commands.
switch-macmap To retrieve MAC address mapping for the specified switch, or all the switches defined in
'switches' table in xCAT db.

osdeploy
========
**osdeploy** operating system provision process. Supports two modes - 'Realtime monitor' and 'Replay history'.
Realtime monitor: This is a default. This tool with monitor provision state of the node. Trigger 'Realtime monitor' before rebooting target node to do provisioning.
Replay history: Used after provisioning is finished to probe the previously completed provisioning.
**Note**: Currently, hierarchical structure is not supported.
Usage
-----
::
xcatprobe osdeploy -h
xcatprobe osdeploy -n <node_range> [-t <max_waiting_time>] [-V]
xcatprobe osdeploy -n <node_range> -r <xxhxxm> [-V]
Options:
* **-n**: The range of nodes to be monitored or replayed.
* **-r**: Trigger 'Replay history' mode. Follow the duration of rolling back. Units are 'h' (hour) or 'm' (minute). If unit is not specified, hour will be used by default.
* **-t**: The maximum time to wait when doing monitor, unit is minutes. default is 60.
* **-V**: Output more information.
``-r`` means replay history of OS provision, if no ``-r`` means to do realtime monitor.
Realtime monitor
----------------
To monitor OS provisioning in real time, open at least 2 terminal windows. One to run ``osdeploy`` probe: ::
xcatprobe osdeploy -n cn1 [-V]
After some pre-checks, the probe will wait for provisioning information, similar to output below: ::
# xcatprobe osdeploy -n c910f03c17k20
The install NIC in current server is enp0s1 [INFO]
All nodes which will be deployed are valid [ OK ]
-------------------------------------------------------------
Start capturing every message during OS provision process......
-------------------------------------------------------------
Open second terminal window to run provisioning: ::
nodeset cn1 osimage=<osimage>
rpower cn1 boot
When all the nodes complete provisioning, the probe will exit and display output similar to: ::
# xcatprobe osdeploy -n c910f03c17k20
The install NIC in current server is enp0s1 [INFO]
All nodes which will be deployed are valid [ OK ]
-------------------------------------------------------------
Start capturing every message during OS provision process......
-------------------------------------------------------------

==================osdeploy_probe_report=================
All nodes provisioned successfully [ OK ]
If there is something wrong when provisioning, this probe will exit when timeout is reachedd or ``Ctrl+C`` is pressed by user. The maximum time can be set by using ``-t`` as below(default 30 minutes) ::
xcatprobe osdeploy -n cn1 -t 30
Replay history
--------------
To replay history of OS provision from 1 hour 20 minutes ago, use command as ::
xcatprobe osdeploy -n cn1 -r 1h20m
Outout will be similar to: ::
# xcatprobe osdeploy -n c910f03c17k20
The install NIC in current server is enp0s1 [INFO]
All nodes which will be deployed are valid [ OK ]
Start to scan logs which are later than *********, waiting for a while.............

xcatmn
======
**xcatmn** can be used to check if xcat has been installed correctly and is ready for use.
**Note**: For several check items(eg. tftp service, dns service, http service), 'tftp', 'nslookup' and 'wget' are need. If not installed, a warning message will be displayed..
Command is as below ::
xcatprobe xcatmn -i <install_nic> [-V]
* **-i**: [Required] Specify the network interface name of provision network on management node.
* **-V**: Output more information for debug.
For example, run command on Management Node ::
xcatprobe xcatmn -i eth0
Output will be similar to: ::
# xcatprobe xcatmn -i eth0

**[MN]** means that the verfication is performerd on the Management Node. Overall status of ``PASS`` or ``FAILED`` will be displayed after all items are verified..
Service Nodes are checked automatically for hierarchical clusters.
For Service Nodes, the output will contain ``[SN:nodename]`` to distinguish different Service Nodes.
