getGuids.README
|
|
|
|
This README describes how to use the getGuids script.
|
|
|
|
The syntax of the getGuids command is:
|
|
|
|
getGuids [-h] [-f output_file]
|
|
-f output_file
|
|
Specifies a file full path name that is used to save the
|
|
GUIDs output.
|
|
-h
|
|
Display usage information.
|
|
|
|
The getGuids is a sample script to get GUIDs for Infiniband Galaxy HCAs
|
|
(Host Channel Adapter) and their ports from xCAT Management Nodes. It
|
|
needs to be run from xCAT Management Node, and will use dsh to all
|
|
the xCAT Managed Nodes so that it could use ibstat command on AIX system
|
|
or ibv_devinfo command on Linux system to get the information about the
|
|
IB devices.
|
|
|
|
If dsh is unreachable for certain nodes, getGuids will give a warning
|
|
message to the user and recommend configuring dsh for these nodes. If
|
|
ibstat or ibv_devinfo command is not available on the target nodes,
|
|
getGuids will give a warning message to indicate that could not get
|
|
GUIDs on these nodes.
|
|
|
|
The output of this script will be printed to the screen and also saved
|
|
into output file, which could be specified by -f flag; otherwise, xCAT
|
|
will use the default output file /var/opt/xcat/ib/Guids.xcat.
|
|
|
|
The format for the output file is <Node: Device: Type: GUID>, for example:
|

|
|
This output file will be used by annotatelog script to organize the log
|
|
entries gathered onto the xCAT MN through remote logging. This script is
|
|
not necessary for non-Galaxy adapters because users can give the adapter
|
|
names directly and do not need the GUID map.
|
|
|
|
getGuids will get IB GUIDs from all the AIX nodes and Linux nodes that
|
|
are defined on the xCAT Management Node (MN); for the nodes that are
|
|
not defined on xCAT MN, if user wants to get GUIDs for these nodes too,
|
|
please define them as xCAT Management Node first and configure dsh before
|
|
using getGuides script.
|
|
|
|
The log file for the script getGuids is /var/log/xcat/getGuids.log.
|
|
The supported hardware types of the nodes gathered GUIDs from are POWER6
|
|
HV4/HV4+, POWER6 HV8/HV8+ and POWER6 IH.
