Discovering PDUs
|
|
================
|
|
|
|
xCAT provides `pdudiscover` command to discover the PDUs that are attached to the neighboring subnets on xCAT management node. ::
|
|
|
|
pdudiscover [<noderange>|--range ipranges] [-r|-x|-z] [-w] [-V|--verbose] [--setup]
|
|
|
|
xCAT uses snmp scan method to discover PDU. Make sure net-snmp-utils package is installed on xCAT MN in order to use snmpwalk command. ::
|
|
|
|
Options:
|
|
--range Specify one or more IP ranges. Each can be an ip address (10.1.2.3) or an ip range
|
|
(10.1.2.0/24). If the range is huge, for example, 192.168.1.1/8, the pdu
|
|
discover may take a very long time to scan. So the range should be exactly
|
|
specified. It accepts multiple formats. For example:
|
|
192.168.1.1/24, 40-41.1-2.3-4.1-100.
|
|
|
|
If the range is not specified, the command scans all the subnets that the active
|
|
network interfaces (eth0, eth1) are on where this command is issued.
|
|
-r Display Raw responses.
|
|
-x XML formatted output.
|
|
-z Stanza formatted output.
|
|
-w Writes output to xCAT database.
|
|
--setup Process switch-based pdu discovery and configure the PDUs(it included passwordless , change ip address from dhcp to static and snmp configuration). It required predefined PDU node definition with switch name and switch port attributes for mapping. (Notes: only support for crpdu for now for this options)

Define PDU Objects
|
|
------------------
|
|
|
|
|
|
#. Define pdu object ::
|
|
|
|
mkdef f5pdu3 groups=pdu ip=50.0.0.8 mgt=pdu nodetype=pdu pdutype=irpdu
|
|
|
|
#. Define switch attribute for pdu object which will be used for pdudiscover **--setup** options. ::
|
|
|
|
chdef f5pdu3 switch=mid08 switchport=3
|
|
|
|
#. Add hostname to /etc/hosts::
|
|
|
|
makehosts f5pdu3
|
|
|
|
#. Verify the SNMP command responds against the PDU: ::
|
|
|
|
snmpwalk -v1 -cpublic -mALL f5pdu3 system
