[xcat-user] Querying database

[Bradford, Matthew]

Lissa,

 

Thanks for that. 

 

We are hoping to do a couple of things.

 

1)      Add additional parameters into the SITE table so we can define
other servers/values which are relevant to our builds. (Will our own
parameters be extracted in to the environment?)

2)      Query different tables to extract noderange specific values for
things like nfsservers etc.  We don't have a common build due to compute
nodes being of various hardware, so we may require to obtain different
values for different nodes.

Thanks very much

 

Mat

Not from a compute node.   What we do though, is if your postinstall
script is setup in xCAT, that is in /install/postscripts  and in the
xCAT postscripts table,   when we run it we export all the attributes in
the site table.    What information are you looking for? 
So when your postscript runs it is in a script that looks like this with
all these exports set : 


NTPSERVERS='9.10.228.45,time.rchland.ibm.com, 9.10.225.159' 
export NTPSERVERS

[xcat-user] Querying database

 

		




Is it possible to query the xCAT database from within a post install
script? 

We are using xCAT 2.1. 

Cheers,
