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

28 Oct 15 Keeping track of san disks
HP-UX does not make it easy to keep track of SAN presented disks. HBA switch ports are in short supply in many data centers. It is important for performance and reliability to be able to account for how many disks are presented to what HBA WWN ports.
This articles outlines a generic method of doing so. It is better than fcmsutil output but is based only on tools provided with the OS (with 1 small exception).
To make sharing easier, I will provide links to scripts. It is up to you to perform due diligence. The scripts write no data and do not change your system. They are provided without warranty under US Law by ISN Corporation.
I recommend against cutting and pasting scripts from this web page, errors are introduced. They are based on korn shell and do not work with bash shell. They probably work on POSIX shell but were not tested. They are specific to HP-UX B.11.31 but can if you wish be adapted to older versions of the OS.
Links to scripts are at the bottom of the post which is quite long.
Script names accurately describe their functionality
fcdisplaydev.ksh us a utility script designed to provide fcmsutil output to the other two scripts.

San boot system.
HBA has to be replaced.
Then you have to boot single user mode to re-establish all your paths.
Procedure authored by my colleague Mahesh Koduru
Before you start make sure you have a current map file hosted on root filesystem.
“Reboot the server and follow these steps :
Interrupt the boot and boot the system in maintenance mode.
fs0:\EFI\HPUX> hpux
HPUX> boot -lm –lq vmunix This will bring the System into Maintance mod
#vgdisplay vg00 The VG should be in deactivated Mod
#ll /dev/*/group Collect the Group file
#vgexport -p -s -m vg00.map /dev/vg00 Keep the Map file in present directory , ie root

Patch Depot tutorial
So you downloaded your QPK after doing swainv analysis of what patches your HP-UX server fleet needs. You have a bundle, but you do not want the default name bundle. No problem use the create script to customize:
The following command sets the bundle name (-b ) and the tilte of the bundle ( -t )
./create_depot_hpux.11.31 -b 201510HPUXPATCHMYCOMPANY -t MYCOMPANYFALL2015
… some output
A directory depot is created
cd depot
Check the bundle list. The names should be meaningful
swlist –l bundle –s $PWD
# Initializing…
# Contacting target “myhost”…

# Target: myhost:/Depots/tmp/depot

20 Apr 15 Serviceguard cluster creation:tip of the day
The following command conducts a cleanup and preparation step for any nodes named in a serviceguard cluster.
It is something I should have known, but learned recently:
cmpreparecl -n sgnode0 -n sgnode1
It does all the steps that would normally be done by hand.

03 Mar 15 Making sure MWA is running properly
What follows is a health check script that checks the installation status of HP Operations Agent and the run status of the two mwa daemons that measure performance.
When run with the -y parameter the script will attempt to correct installed status of HP Operations Agent.
If you want the script, please email me via the sites response form. Cutting and pasting from this site can be done, but may be a very frustrating endeavor.
I have added commentary to the script, which may introduce run errors if screen scraped.
