Try running
swainv.
Then upload the generated inventory.xml to
IT Resource Center (You'll need to register).
From there under "maintenance and support (hp products)" select 'patch database'.
Under "patch database" there is an option to 'run a patch assessment'.
When you reach the "run a patch assessment" page, there's an option to 'upload new system information', which is where you'll upload the inventory.xml file mentioned earlier.
Then after that's uploaded, you can "display candidate patches".
Hope that helps some.
