28 Nov 17 An xpinfo that works in hpvm guests and on non Hitachi storage
Hitachi shops faced annoyance times two:
1. xpinfo does not work on non-Hitachi storage for example Pure storage
2. xpinfo does not work on hpvm guests depending on how the storage is passed through from the hpvm host
I now present xpinfonew which though raw and unfnished
The output:

01 Aug 17 Need a longer hostname 8+ Don’t forget the kernel parameter
Host names need to be descriptive. The trend toward longer names has been going on for years.
As a legacy Unix, HP-UX CAN keep up.
kctune -v expanded_node_host_names
mygush0:root > kctune -v expanded_node_host_names
Tunable expanded_node_host_names
Description Enables expanded node and host names (read manpage for warnings)
Module sysconfig
Current Value 0 [Default]
Value at Next Boot 0 [Default]
Value at Last Boot 0
Default Value 0
Constraints expanded_node_host_names >= 0
expanded_node_host_names <= 1
Can Change Immediately or at Next Boot
hostname is set in /etc/rc.config.d/netconf
But to make the system fully compatible the kernel needs to be set.
mygush0:root > kctune expanded_node_host_names=1
==> Update the automatic ‘backup’ configuration first? y
* The automatic ‘backup’ configuration has been updated.
* Future operations will update the backup without prompting.
WARNING: Setting the expanded_node_host_names parameter to 1 will allow
administrators to set node and host names larger than 8 and 64
characters/bytes, respectively. It is strongly recommended
that all related manpages and documentation be understood
before setting larger names. Larger names can cause some
applications which use those names to behave incorrectly or
fail.
* The requested changes have been applied to the currently
running configuration.

28 Apr 17 Handle with care: TCP wrappers /etc/hosts.allow
Real life story.
DMZ based server dedicated to SFTP was configured with sshd rules in /etc/hosts.allow
sshd : ALL@16.89.97.*:ALLOW
sshd : ALL@14.251.*:ALLOW
sshd : AAL@208.94.61.*:ALLOW
Should have been:
sshd : ALL@16.89.97.*:ALLOW
sshd : ALL@14.251.*:ALLOW
sshd : ALL@208.94.61.*:ALLOW
That network was the firewall to the outside world.
The end users were inconvenienced and the firewall team wasted a lot of time reviewing rues and looking at logs.

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:

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.
