Machinfo on PA-RISC systems
When the HP-UX Itanium version was released it came with a very handy tool named machinfo. This command prints number and type of CPUs, amount of memory, firmware revision, serial number, machine id and many more useful information about the server. Sadly on PA-RISC we didn’t have something similar, of course there is print_manifest and I have to say that it’s quite a tool but I always loved the simplicity of machinfo.
Dozens of posts have been thrown throughout the years on ITRC Forums asking for a PA-RISC machinfo version and many workarounds and even some binaries have been posted.
I tried a lot of them but since I discovered Patrick Reut‘s version a couple of years ago I never used another one. It works on 11.11 and 11.23 systems, I tried on 10.20 but didn’t wok. The binary can found in this post as an attachment.
Here it an example output of the command:

Linux LVM commands in HP-UX
Some of the features I always liked about the Linux LVM2 implementation are the lvs, vgs and pvs command. with this simple commands a short list of the LVs, VGs and PVs active on the system can be obtained.
www04:~ # vgs VG #PV #LV #SN Attr VSize VFree vgwww01 1 6 0 wz--n- 39.75G 6.25G vgbbdd 3 3 0 wz--n- 94.25G 0 vgsys 1 6 0 wz--n- 34.74G 1.25G www04:~ #
In HP-UX there is nothing similar available, well since HP-UX 11.31 and LVM2 a “-F” option has been added to produce a formated, more script friendly list but is not very “human readable”.

Because of this I decided to write three scripts to emulate the behavior of vgs, lvs and pvs on my HP-UX servers. This scripts take advantage of the mentioned LVM2 “-F” switch so they will not work on HP-UX 11.23 or any other previous versions. If anyones recognize the “scripting” style is because I grab some parts of the code from Olivier’s ioscan_fc2.sh and adapted them to my needs so credit goes to him also :-)
- VGS: List the volume group on the /etc/lvmtab file, if the server is part of a cluster the volume groups active on other nodes will be showed as deactivated. With the “-v” switch single VGs can be queried.
root@cldpp01:~# ./vgs.sh VG PVs LVs Status Version VGSize Free vg00 1 9 available 1.0 135G 77G vgdpp 1 1 available,exclusive 1.0 49G 0G vgidbbck deactivated root@cldpp01:~# ./vgs.sh -v vgdpp VG PVs LVs Status Version VGSize Free vgdpp 1 1 available,exclusive 1.0 49G 0G root@cldpp01:~#

Playing with lanadmin & lanscan
Current release of HP-UX, 11.31, has the handy nwmgr to handle networking tasks, but for years instead of nwmgr we’ve been playing with lanscan and lanadmin (linkloop as well) to perform many networking tasks on the 11.23 release and previous ones. And surely some of you, just like myself, still have 11iv2 systems up and running. Following is a small list of tips and tasks for lanadmin from one of my “how-to-do” files.
- Lanscan: Basically is used to get information about the LAN interfaces.
root@sap01:~# lanscan Hardware Station Crd Hdw Net-Interface NM MAC HP-DLPI DLPI Path Address In# State NamePPA ID Type Support Mjr# 0/0/0/1/0 0x001A4B07F002 0 UP lan0 snap0 1 ETHER Yes 119 0/0/0/1/1 0x001A4B07F003 1 UP lan1 snap1 2 ETHER Yes 119 0/0/1/1/0 0x0018FE2D7EE7 2 UP lan2 snap2 3 ETHER Yes 119 0/0/9/1/0 0x0018FE2D7EF4 3 UP lan3 snap3 4 ETHER Yes 119 0/0/10/1/0 0x000CFC0046B9 4 UP lan4 snap4 5 ETHER Yes 119 0/0/12/1/0 0x000CFC004672 5 UP lan5 snap5 6 ETHER Yes 119 LinkAgg0 0x000000000000 900 DOWN lan900 snap900 9 ETHER Yes 119 LinkAgg1 0x000000000000 901 DOWN lan901 snap901 10 ETHER Yes 119 LinkAgg2 0x000000000000 902 DOWN lan902 snap902 11 ETHER Yes 119 LinkAgg3 0x000000000000 903 DOWN lan903 snap903 12 ETHER Yes 119 LinkAgg4 0x000000000000 904 DOWN lan904 snap904 13 ETHER Yes 119 root@sap01:~#
A verbose version can be obtained with the -v switch, but for me this switch has a glitch since you can’t query for a single LAN card:
root@sap01:~# lanscan -v ------------------------------------------------------------------------------- Hardware Station Crd Hdw Net-Interface NM MAC HP-DLPI DLPI Path Address In# State NamePPA ID Type Support Mjr# 0/0/0/1/0 0x001A4B07F002 0 UP lan0 snap0 1 ETHER Yes 119 Extended Station LLC Encapsulation Address Methods 0x001A4B07F002 IEEE HPEXTIEEE SNAP ETHER NOVELL Driver Specific Information iether ------------------------------------------------------------------------------- ... root@sap01:~#
There are other options for lanscan that can be used to obtain more simple info in a “script friendly” list format:
root@sap01:~# lanscan -a 0x001A4B07F002 0x001A4B07F003 0x0018FE2D7EE7 0x0018FE2D7EF4 0x000CFC0046B9 0x000CFC004672 0x000000000000 0x000000000000 0x000000000000 0x000000000000 0x000000000000 root@sap01:~# lanscan -i lan0 snap0 lan1 snap1 lan2 snap2 lan3 snap3 lan4 snap4 lan5 snap5 lan900 snap900 lan901 snap901 lan902 snap902 lan903 snap903 lan904 snap904 root@sap01:~#
- Lanadmin: The lanadmin, acording to its man page, allow you to:
+ Display and change the station address.
+ Display and change the 802.5 Source Routing options (RIF).
+ Display and change the maximum transmission unit (MTU).
+ Display and change the speed setting.
+ Clear the network statistics registers to zero.
+ Display the interface statistics.
+ Display the interface usage information.
+ Reset the interface card, thus executing its self-test.
+ Configure VLANs on the cards that support VLAN.
It can be used in two ways, if invoked with no options from the shell it will present a menu style interface where different tasks can be performed. Following is am example to illustrate.

SSH foolishness
Today it’s been one of those days that you wish to hide very deep under your desk.
For a couple of days I’ve been battling with a 11.31 server over its sshd configuration, somehow this was the only node which refused the public-key ssh authentication method from my management server and always asked for root password, that means I could’t run scripts remotely with a convenient for loop over the sever list, no remote tests, no cron tasks from the management node against it, etc; and that’s unacceptable for me.
I almost wiped out the config of the target server and recreated it from scratch using the sshd_config file of a working 11.31 node as my starting point and still the damn server asked for a password. I was desperate, looking through the config file one time after another, checked file permissions, running the same test from other servers with same result.
Finally I ask a colleague if he could review my sshd_config file, at first look he found nothing wrong and then he performed some test and MAGIC!! it worked. I asked him about his “guru trick” and he said ‘Dude, your root home had 777 permissions’ ‘WHAT?!?!?!?’
I was terribly embarrassed, one of the first tasks I do after install any HP-UX is to move the root home from / to /root and in this almost newly deployed 11.31 I didn’t change the permissions. Of course I quickly checked all my servers just in case and fortunately for me none of them had a misconfigured sshd.
Two days completely lost finghting against my foolishness, got out of bed on the wrong side this morning.
Oh I almost forgot… thanks Javi, you’re the best :-)

Open Source software and HP-UX
HP-UX is a great OS and the default installation provides a plethora of tools for any Unix sysadmin but of course, like almost every operative system, it can improved with third-party opensource software
This is a short list of the packages I can’t live without, all of them can be obtained at the Porting And Archive Centre for HP-UX or the HP-UX 11i Internet Express collection. The packages included in the Internet Express collection are fully supported and tested by HP.
- Bash shell. The best Unix shell, at least for me, powerful and highly customizable.
- GNU coreutils. Provides with GNU version of many Unix commands, what can I say? I like the GNU ls colored output x-)
- Lsof. How can any sysadmin live without lsof?
- Sudo. Indispensable to allow scripts or users run certain commands as root or any other user.
- Unzip. It’s not that I use it but every time I set up a new server to run Oracle the database people ask for it so I got used to install it.
- Tcpdump. Don’t install it by default on my servers but I like to have the depot around, just in case.
- Tusc. God bless Chris Bertin!
- Vim. Not on my production servers but I like to have VI Improved installed on my management node, usually the Ignite-UX server, where I store all my scripts and with ssh (public key authentication) access to all the nodes.
Of course all of them have dependencies that have to be met, however with the exception of vim, which have tons of them, there aren’t too much.
And that’s all folks, which opensource package do you use in your HP-UX boxes? Please comment :-)

UNIX95 and ps command
UNIX95 is a Unix standard defined in the Single UNIX Specification. HP-UX 11i is registered as UNIX95 compliant in its v1 and v2 versions and as UNIX03 (a more modern version) the v3.
This standard affect commands and syscalls in various ways and it is not set by default. To “activate” this mode the UNIX95 environment variable must be declared, it is not recommendable to set the variable through the root profile or /etc/profile. The best way to use the features provided by the UNIX95 standard is to temporally set the variable just before execute a command in the shell.
Currently I only use this mode with the ps command. This command has some options that can only be used if the UNIX95 variable is declared. I have a couple of alias in my profile to take advantage of this options.
- With this command you can get a sort of equivalent of the Solaris ptree command.
root@asoka:/# alias ptree alias ptree='UNIX95=1 ps -eHf'
- Get the top 15 CPU consuming processes:
root@asoka:/# alias pcpu alias pcpu='UNIX95=1 ps -ef -o pcpu,user,pid,args | /bin/sort -u -r | sed -e '\''s/\.[0-9][0-9]/&\%/g'\'' | sed -n 1,15p' root@asoka:/# pcpu 0.83% root 10520 /opt/wbem/lbin/cimprovagt 0 5 10 root SFMProviderModule 0.51% hpsmh 10434 /opt/hpws/apache/bin/httpd -k start -DSSL -f /opt/hpsmh/conf/smhpd.conf 0.45% root 53 vxfsd 0.42% cimsrvr 10518 cimservermain --executor-socket 5 0.16% root 1904 vxsvc -r /opt/VRTSob/config/Registry -e 0.13% root 552 /usr/sbin/utmpd 0.12% root 1468 /opt/dce/sbin/rpcd 0.11% root 39 schedcpu 0.10% root 10523 /opt/wbem/lbin/cimprovagt 0 5 10 root HPUXFCIndicationProviderModule 0.10% root 1707 /usr/sbin/swagentd -r 0.07% root 26676 sshd: root@pts/1 0.06% root 10525 /opt/wbem/lbin/cimprovagt 0 5 10 root HPUXLANIndicationProviderModule 0.06% root 2296 /usr/sbin/stm/uut/bin/tools/monitor/WbemWrapperMonitor 0.06% root 1028 /usr/sbin/automountd 0.06% root 21 ksyncer_daemon root@asoka:/#
There are more options for ps and for other commands, just investigate a bit in the man pages.
