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.

03 Mar 15 scopeux and midaemon don’t want to run
midaemon and scopeux combine to collect performance data on HP-UX.
They both need to be running to properly collect data.
These are part of a depot called measureware which is part of the base OS.
To see if it is installed:
swlist -l bundle TC097EA
myserv0:root > swlist -l bundle TC097EA
# Initializing…
# Contacting target “myserv0″…
#
# Target: myserv0:/
#
TC097EA 11.20.000 HP Operations Agent
If not installed, HP Operations Agent can be downloaded from HP if you have a software contract with HP.
It is also delivered as part of openview, which is a separately licensed product.
I recently implemented performance data collection on a fleet of 100+ servers where I work.
On three of the servers, the daemons refused to run normally.
The following error was recorded in the file /var/opt/perf/status.mi
Unable to find newly enabled CPU.
Please use -prealloc to allocate bufsets for all CPUs.
Here are the steps to implement.
mwa stop all
/opt/perf/bin/ovpa stop
/opt/perf/bin/pctl stop
perfstat
kill any processes gently identified as running in perfstat output.
Edit the file /etc/rc.config.d/ovpa
MIPARMS=”-prealloc=2 -pids 10000 -kths 10000 -smdvss 512M”
export MIPARMS
2 is the number of physical cpus in the box.
If present the file /var/opt/perf/datafiles/RUN should be deleted.
mwa start all
perfstat
Check back in 1 hour and one day that midaemon and scopeux are still running.
Check /var/opt/perf/datafiles for updated log files.

24 Feb 15 Server backplane layout for rx class servers
HP-UX hardware is a bit Byzantine in nature. The following script demystifies things a bit and allows us to work at remote data centers with accuracy on cable issues both fiber and copper.
If you want to use this script, use the contact form to reach out to me. Most people will find cutting and pasting from the website very frustrating.
I am also reaching out to the community, dare I say fan base for assistance. I am fairly certain that the fiber side accurately reports status of hba connections. I am fairly certain that the copper side needs to be improved.
This is tested on rx7640 and rx8640 systems. I am fairly confident that it will work on superdomes. I just do not happen to have any around to test on.
Script includes an environment plugin called .scriptenv . I will provide relevant code from it as some of what it does is customer specific and can not be released into the wild. If functionality is needed everywhere, I try to provide it via a centrally managed file. I provide functionality to both command prompts and scripting this way. It allows me to make the scripts generic and change one file with environment customizations.
Script is based on olrad -q output. It uses several deprecated utilities such as lanadmin and lanscan. Since I currently doubt HP-UX v4 is in the works, this should not be a problem.
The output then the script:
IP addresses and mac addresses have been changed to protect the innocent:

HP-UX 11.31 September 2011 OE.
A good day is an awkful day.
11 Jul 12 Online JFS filesystem expansion without umount
This requires add in software from Veritas/Symmantec that can be expensive on HP-UX.
Lets say we want to extend /var which is lvol8.
It was originally 600 LE and we extended it as follows.
lvextend -l 800 /dev/vg00/lvol8 /dev/disk/disk25_p2
The 800 refers to LE logical extents. I prefer to use this rather than MB because it corresponds to the values displayed by most lvm utilities. -L <value in megabytes> can be used. I assume you can do the math here.
[system099]/root # lvdisplay /dev/vg00/lvol8
— Logical volumes —
LV Name /dev/vg00/lvol8
VG Name /dev/vg00
LV Permission read/write
LV Status available/syncd
Mirror copies 1
Consistency Recovery MWC
Schedule parallel
LV Size (Mbytes) 12800
Current LE 800
Allocated PE 1600
Stripes 0
Stripe Size (Kbytes) 0
Bad block on
Allocation non-strict
IO Timeout (Seconds) default
It was originally 600 LE and we extended it as follows.
lvextend -l 800 /dev/vg00/lvol8 /dev/disk/disk25_p2
fsadm -F vxfs -b 12800M /var
This command will use online JFS to extend the filesystem. The alternative is extendfs. But that requires a umount. Or perhaps xvumount -o force. Your choice, I don’t recommend it, but did test it the other day in the sandbox.
Now if you want to be cute and use all your space, try this.
SIZE=$(lvdisplay /dev/vg00/lvol8 | awk ‘/LV Size/ {print $NF}’);
ESIZE=”${SIZE}M”
fsadm -F vxfs -b $ESIZE /var
You can get more cute and do it with a single command line but I’m not going to do that. I have not broken any systems this week and am trying to avoid that.

07 Jun 12 awk trick of the day(month?) parsing bdf output. awk with if else logic
Ever try and do system reporting based on bdf?

then

06 Apr 11 setboot hardware path to legacy hardware path. A converter.
HP-UX 11.23
setboot provides output only including the hardware path (ioscan -H).
When calculating DRD clone targets and such you need the regular legacy device path.
Here is a converter, built with a little help from JRF on the ITRC forums.
First get the setboot path. Might want to use the full path of the setboot command in practice.
pboot=$(setboot | grep ^Primary | awk ‘{ print $NF }’);
aboot=$(setboot | grep ^Alternate |awk ‘{ print $NF}’);
abootdisk=$(ioscan -kfnCdisk | awk -v aboot=${aboot} ‘/aboot/ $0~aboot {getline;print aboot,$2}’ | awk ‘{ print $2 }’);
pbootdisk=$(ioscan -kfnCdisk | awk -v aboot=${pboot} ‘/pboot/ $0~pboot {getline;print pboot,$2}’ | awk ‘{ print $2 }’);
The slick part is getting the variable in and out of awk.
Uses ioscan.

30 Nov 10 awk trick of the day. Parsing comma delimited input to a sequential file
Lets say I have a list of servers a mile long to visit. Got a help desk request with the servers listed separated by commas.
server1,server2,server3
Lets say It is actually about 30 or 40 servers and I’m too lazy to edit the list
echo “server1,server2,server3” > olist
awk -F, -v nr=1 ‘{ for (x=nr; x<=NF; x++) {printf $x ” \n”; }; print ” ” }’ olist
Output:
server1
server2
server3
Plug and play time here, you can take care of any delimited format like this.

nwmgr -s -f -c lan1 -A mtu=1500 –cu
### change mtu on lan1 to 1500 (lanadmin -M 1 1500)
Found some really useful information on APA. So good I won’t risk it disappearing. Pretty much here for my own reference.

01 Jul 10 Quick and dirty awk trick to see all Fiber Channel status
I needed to update documentation and I needed more information that my prior syslayout.sh script provided on fiber.
# Improvement by JRF on the ITRC forums.
ioscan -kfnC fc | awk ‘/fcd/ {getline;fcd=$NF;print fcd,$2}’ | while read -r fdev
do
fcmsutil ${fdev} | awk ‘/Hardware / {print $5};/World / { print $7}’
done
Ouput looks like this:
0/0/12/1/0/4/0
0x5001438002a24979
0x5001438002a24978
0x204f000dec81b540
0x200f000dec81b541
0/0/12/1/0/4/1
0x5001438002a2497b
0x5001438002a2497a
0x2093000dec81b480
0x2010000dec81b481
2/0/12/1/0/4/0
0x5001438002a24d35
0x5001438002a24d34
0x2050000dec81b480
0x2010000dec81b481
2/0/12/1/0/4/1
0x5001438002a24d37
0x5001438002a24d36
0x2093000dec81b540
0x200f000dec81b541
Second, new improved version (Girsah Chadash)
ioscan -kfnC fc | awk ‘/fcd/ {getline;fcd=$NF;print fcd,$2}’ | while read -r fde
v
do
fcmsutil ${fdev} | awk ‘/Hardware / {print $5};/World / { print $7}’ | awk’ {printf “%s %s %s %s %s”,$1, $2, $3, $4, $5;}’
fcmsutil ${fdev} | awk ‘/Hardware Path/ {PATH=$5};
/N_Port Node/ {NNODE=$7};
/N_Port Port/ {NPORT=$7};
/Switch Port/ {SPORT=$7};
/Switch Node/ {SNODE=$7};
END{print PATH, NNODE, NPORT, SPORT, SNODE}’
done
Next innovation would be to combine the awk statements in the while loop and pull off the output with a single awk command. I may do this, but I might need help from an awk guru.
The ioscan output is multi line, so the real innovation is using the getline function of awk to get the second line of data and ignore the first. The filter /fcd gets rid of the column format information.
Yes it could be done with grep, but it is more AWKFUL this way.
Updated document to provide some indentation. Trying to make the code easier to read. That may force me to add formatted scripts to download, which I will get to as time permits.
