When you use drd to patch and update systems offline to reduce downtime there is an unintended impact: setboot issues.<\/p>\n
Using HP best practices after you boot the new image the setboot -a (alternate) and -p (primary) settings are often the same.<\/p>\n
Below is an audit and correction script that helps you track the issue and limit manual intervention and the human error it can introduce:
