Thanks Arif. If the node is statelite, am I correct in assuming that the
command would be:
nodeset <nodename> statelite

Hi David,
If you are using diskless nodes, on e you have updated the tables all you need
to do is
nodeset <nodename> netboot
And then reboot the nodes. This should automatically change the relevant tftp
files.
However if this is disk full, then you need to run the following command
nodeset <nodename> install
This should then reconfigure your kick start files and the tftp files and once
rebooted it should pick up the relevant files
I hope that helps
Regards,
Arif

I have a cluster configuration which contains some RHEL 6.1 nodes and some RHEL
6.2 nodes. I simply wanted to change a few of the nodes from 6.1 to 6.2.
Initially, I thought all I needed to do was to change the settings for that
node in the nodetype table, but that did not work. The node still booted as
RHEL 6.1.
Then I updated the information in the bootparams table. Still booting as 6.1.
I examined the information being written to the console during boot, and saw
that the file (on the Mgt Server) /tftpboot/etc/<nodeMacAddr> was being tftp'd
over to the node at the beginning of the boot process. When I updated that file
to use the RHEL 6.2 boot image rather than the 6.1 image, the node finally
booted with the RHEL 6.2 OS.
For another RHEL 6.1 node, I tried the same thing, but I updated the
/tftpboot/etc/<nodeMacAddr> file first. Again, the node rebooted as RHEL 6.2,
but the xCAT tables (nodetype, bootparams, etc.) are still showing RHEL 6.1
information for that node.
Do I have to manually update the xCAT tables *and* the
/tftpboot/etc/<nodeMacAddr> file when I want to change a node's OS release from
RHEL 6.1 to RHEL 6.2 (or any other release that I have configured)?
Thank you.
