OS upgrade on all nodes

On the UI, one needs to make sure that at this stage no grid software is updated.

yum update --disablerepo=glite-UI --disablerepo=dag

Take a look at the /boot/grub/menu.lst file and make sure that the kernel boot parameters include the console redirection options console=ttyS0,9600!!!

MW upgrade on the UI

Update the rest of the package, now with the enabled MW repositories

yum update

Test the new YAIM version against the existing node config:

cd /root/YAIM-config
/opt/glite/yaim/bin/yaim -v -c -s site-info.def -n glite-UI

Edit /opt/glite/etc/profile.d/grid-env.sh as described on the NodeTypeUserInterface page.
