System is SUSE sles11 sp1.
I have specified in my YAST2 that i want some of the following patterns to be installed:
file_server
gateway_server
gnome
kde
lamp_server
mail_server
laptop
among many others.
I didnt get any notification that there was an error and they didnt get installed.Question is : How do I check i have those patterns installed.

Since i didn`t get an answer i researched the matter myself.Let me @ least provide a solution so we can finalize this threat.
1.mount the whole iso that you have installed via mount command
mount -o nolock pathofthemediayouwant2mount /mnt
2.use zypper to add the repo
zypper ar nfs://pathofthemediayouwant2mount
3.zypper lr (to view contents)
4.zypper se -t pattern(will show you all patterns.If they have an i on the left side that means they have been installed)

In case you find something that has not been installed you can install it manually by typing:
zypper in -t pattern nameofyourpattern

Thats it!
