Satellite6 Package update question

Hello,

I am running hammer update all command to update packages. I have noticed its not removing the old kernels. Is this expected?

Also how do you track the systems that are failed to update? Our environment is large and wanted to automate the package pushes. I am unable to find a way to capture error messages (systems that are failed to patch) without going thru each task manually in the GUI . Any suggestions?

Thanks in advance.

Regards
Ramesh
