Using updatenode is one way. What level of xCAT are you running? Are
these diskless or diskful installed compute nodes?
This is a good document to follow:

Subject: [xcat-user] Applying updates (rpms) to compute nodes
Hello,
I wondered if someone could please advise me on how best to update rpms on
my compute nodes via xcat. In fact I have a number of updates and one new
rpm installation to do. I’ve downloaded all the required rpms and have a
test solution on one of the compute nodes. I’m just considering how to
generalize this in xcat.
I’m looking at installing Xvfb on our compute nodes for a user. The rpm
called xorg-x11-server-Xvfb does not exist in the standard RHELS
distribution, however it is possible to provide a solution via the
following recipe:
rpm -Uvh openssl-1.0.1e-16.el6_5.7.x86_64.rpm
openssl-devel-1.0.1e-16.el6_5.7.x86_64.rpm
rpm -Uvh pixman-0.26.2-5.1.el6_5.x86_64.rpm
xorg-x11-server-common-1.13.0-23.1.el6_5.x86_64.rpm
rpm -ivh xorg-x11-server-Xvfb-1.13.0-23.1.el6_5.x86_64.rpm
rpm -Uvh libXfont-1.4.5-3.el6_5.x86_64.rpm
The only new installation here is xorg-x11-server-Xvfb. All the other rpms
are upgrades of existing packages installed on the compute nodes. I still
need to verify that that this solution (to provide Xvfb) does work for
sure. On that assumption, could you please advise me how best to integrate
these changes in to the xcat compute node image. For example can we
potentially use /install/post/updates on the xcat server?
Best regards – David.
