15 Jan 16 Automated setboot check and correction
When you use drd to patch and update systems offline to reduce downtime there is an unintended impact: setboot issues.
Using HP best practices after you boot the new image the setboot -a (alternate) and -p (primary) settings are often the same.
Below is an audit and correction script that helps you track the issue and limit manual intervention and the human error it can introduce:
myserv0:root > cat 349_bootconf

#
# The point here is there should be an a primary boot disk
# and an alternate boot disk and they need to be different
#
pboot=$(/usr/sbin/setboot | grep ^Primary | awk ‘{ print $NF }’ | awk -F\/ ‘{print $NF}’ |

This is wrong but is a known issue that results from my patch methodology
First step to fixing is to confirm current booted details and drd details
mysys03:root > lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/disk/disk2490_p2 — Boot Disk

Root: lvol3 on: /dev/disk/disk2490_p2
Swap: lvol2 on: /dev/disk/disk2490_p2
Dump: lvol2 on: /dev/disk/disk2490_p2, 0
