16 Dec 21 Linux vgs port for HPUX (updated to work with vg version 2.2)

A while back, I came across a port of the very nice linux vgs command for HP-UX. A h/t to Juan Manuel Rey (juanmanuel.reyportal@gmail.com) for that original version.

But, upon using it recently, I noted it was not working now that we have some volume groups with vg version 2.2. Here is a modified version of the script that works for version 2.2 volume groups!

#!/sbin/sh

16 Dec 21 “Subtracting” one file from another

I recently had the occasion to refactor a script (not mine) in which there was some convoluted logic to ensure that the contents of file A (an ascii file) were fully contained within file B (another ascii file). Lots of looping and grepping were the order of the day. I imagined that there had to be better way and first went down the path of using grep with a file as the source of the things I was looking for. However, while that would get me partially there, it would not tell me if File A was wholly contained with file B. I am sure I could made it work (somehow) using this idea, but again, I thought that there has to be a better way.

With the help of Google (because of course), I stumbled across an HP-UX command (not unique to HP-UX of course) that in my 25 years of scripting on the HP-UX platform, I had never encountered nor used before: the comm command. This command lets one implement set logic on ascii files.

Let’s have a look . . .

From the man page for comm:

 NAME
      comm - select or reject lines common to two sorted files

 SYNOPSIS
      comm [-[123]] file1 file2

DESCRIPTION
      comm reads file1 and file2, which should be ordered in increasing
      collating sequence (see sort(1) and Environment Variables below), and
      produces a three-column output:

       Column 1:   Lines that appear only in file1,
       Column 2:   Lines that appear only in file2,
       Column 3:   Lines that appear in both files.

  If - is used for file1 or file2, the standard input is used.

  Options 1, 2, or 3 suppress printing of the corresponding column.
  Thus comm -12 prints only the lines common to the two files; comm -23
  prints only lines in the first file but not in the second; comm -123
  does nothing useful.

So, “comm -12” performs the intersection operation on the files. But “comm -23” should do the trick for what I was after: Subtracting file B from File A. In my use case File B should be a proper subset of File A. I can test for that via:

checkCount=$(comm -23 $FILE_B_SORTED $FILE_A_SORTED | wc -l)

If the resulting count is “0”, I know that File B is wholly contained within File B. If the count is not “0”, then I can consume what is in File B but not in File A and take appropriate action.

Note that the two ASCII files need to be in sorted order – easy enough. Here is an example of all of this put together to accomplish of “subtracting File B from File A”:

FILE_B_SORTED=$(mktemp)
FILE_A_SORTED=$(mktemp)

sort -u $FILE_B > $FILE_B_SORTED
sort -u $FILE_A > $FILE_A_SORTED

#
# 'comm -23 file1 file2' says show me all the lines that appear in
# file2 but not in file1.  Thus, here, we are ensuring that there is
# nothing in the file2 that is NOT in file1.
#
# We count how many such lines there are - we expect there to be zero.
#

checkCount=$(comm -23 $FILE_B_SORTED $FILE_A_SORTED | wc -l)
if (( checkCount == 0 )); then
   echo "All entries in the File B are in File A  (goodness)"
else
   # Do something with the entries in File B that are not in File A
   checkList=$(mktemp)
   comm -23 $FILE_B_SORTED $FILE_A_SORTED > $checkList
   exec  4< $checkList
   while read entry <&4; do
     # Do whatever is that needs to be done
   done
fi

All good stuff 🙂

17 Jun 20 HP-UX Serviceguard Missing node

If you have a hardware fault or other calamity in a HP-UX serviceguard cluster you lose the ability to make incremental changes to the cluster until that node comes back.

If you need to make a change to a cluster in this state and you don’t want to bring down the cluster, you have to do all your changes with one gigantic command line.

Lets say you have a 4 node cluster named cnode1,cnode2,cnode3, and cnode4.

cnode4 suffers a hardware fault and you packages fail over to cnode1-3. But your usage has grown and you have a package that is beating the hardware down and you want to move it from cnode2 to cnode1.

Well you can’t do it incrementally. You have to do it all at once. I recently ran into a situation where I had to modify 37 cluster environment files and the cluster configuration to remove a node cnode4.

That requires you to correctly type a command line that could easily be in excess of 4000 characters. Anybody who knows my typing skills knows this is beyond my abilities on my best day.

So I wrote a little assistant program.

It consists of three files two of which are scripts.

pkg-mod-list (A list of all the package configuration files, full path that need to be modified. It is your choice how to handle the editing. We used ansible last night when we did it in a DR cluster.

Contents …

/etc/cmcluster/nc-package-name/nc-package-name.env

/etc/cmcluster/sc-package-name/sc-package-name.env

Then we have helper scripts which put the command line together.

myclusterV6_prod.conf is the main cluster configuration file with the references to node cnode4 commented out.

cat missing-node-checkconf
MAIN=”cmcheckconf -C /etc/cmcluster/configs/myclusterV6_Prod.conf”
PCMD=””
cat pkg-mod-list | while read -r pfile
do
PCMD=”${PCMD} -P ${pfile}”
### echo “$PCMD”
done
MYCMD=”${MAIN} ${PCMD}”
echo $MYCMD

exec ${MYCMD}

MAIN=”cmapplyconf -C /etc/cmcluster/configs/myclusterV6_Prod.conf”
PCMD=””
cat pkg-mod-list | while read -r pfile
do
PCMD=”${PCMD} -P ${pfile}”
### echo “$PCMD”
done
MYCMD=”${MAIN} ${PCMD}”
echo $MYCMD

exec ${MYCMD}

13 Nov 19 Using File Descriptors other than stdin/stdout/stderr in Shell Scriptings

For a longish ime, I had to jump through major hoops to script around the issue of my standard input getting clobbered when inside a loop that was iterating over something that coming from stdin. I don’t have an exact example that recreates the issue but something like this would generate lots of headaches:

cat <some file> | awk '{<some fancy awk-type hingys>}' | \
  while read entry; do
    bla; bla; bla
    some_command_here_that_would_whack_stdin
    bla; bla; bla
  done

Sorry I cannot provide an actual snippet of code to recreate the issue but what I would find in these situations is that my loop would end after one iteration (when I knew there should have been a lot more) and I coudn’t figure out why which made me haz a sad.

Well, I found a way to steer clear of all that by assigning a <some file> to a file descriptor different from stdin. To wit:

exec 3< /path/to/file
while read entry <&3; do
   bla; bla; bla
   some_command_here_that_would_whack_stdin
   bla; bla; bla
done

There are no doubt other ways to solve this conundrum but this is the way I have avoided it for quite some time now. Of course, make sure you do not associate a file with file descriptors 0,1,2 (unless you are quite sure that is what you want to do!).

10 Nov 19 How to be a yes man

Learning something new is great. Joe Geiger taught me something cool that I should have learned years ago.

Serviceguard users ever wanted to script a cluster change such as a node add.

cmapplyconf -v -P <package file>

Ends with a y/n prompt do you want to apply? Normally that requires input. Not with the yes command:

cmcheckconf -v -P <package file>

rc=$?

# Check return code if not zero stop

if [ ${rc} -ne 0 ]

then

echo “Checkconf error ${rc}”

exit ${rc}

fi

yes | cmapplyconf -v -P <package file>

# Check return code here as well

15 Aug 19 APA network pairings: How to find out fast what they are

Script for detecting APA network bonded pairs. It is already built into the cinam21t drd image. It will save you 3-5 hours of guess work on future builds.

Networking was changed to protect the innocent.

Here is an example:

[root@cinam21t]:/home/root # ./apanetwork_discover 142.18.1.26 142.18.1.96 ——————————————————— -This script figures out which NIC cards are APA paired.- -It has two inputs:……………………………….- -1- The assigned IP address of the APA Group lan90#…..-
-2- The known network address of an HP-UX server on net.- -ex ./apanetwork_discover 142.18.1.26 142.18.1.96 ……-
– These are cinam21t and stlam31t…………………..-
– The system must be OFF network for this to work ……-
– Instruction: …………………………………..-
– /sbin/init.d/net stop …………………………..-
– /sbin/init.d/vlan stop ………………………….-
– /sbin/init.d/hplm stop ………………………….-
– /sbin/init.d/hpapa stop (You may need to ctrl-break…-
– netstat -rn (ifconfig lan# down then unplumb any lans.-
– Wash,rinse and repeat for lan901,lan902,lan903 …….-
———————————————————
The LAN is lan0 Success lan0 as 142.18.1.26 was able to ping 142.18.1.96 The LAN is lan8 NO JOY lan8 as 142.18.1.26 was able NOT to ping 142.18.1.96
The LAN is lan16 NO JOY lan16 as 142.18.1.26 was able NOT to ping 142.18.1.96
The LAN is lan19 NO JOY lan19 as 142.18.1.26 was able NOT to ping 142.18.1.96
The LAN is lan2 NO JOY lan2 as 142.18.1.26 was able NOT to ping 142.18.1.96
The LAN is lan49 NO JOY lan49 as 142.18.1.26 was able NOT to ping 142.18.1.96
The LAN is lan52 NO JOY lan52 as 142.18.1.26 was able NOT to ping 142.18.1.96
The LAN is lan56 Success lan56 as 142.18.1.26 was able to ping 142.18.1.96 [root@cinam21t]:/home/root #

In this case lan0 are in the bonded pair (lan900)

Take a nwmgr output before bringing network down. Run from console only

Here is the script code

/root/build # cat apanetwork_discover

!/bin/ksh

#

echo “———————————————————“
IP2=$2
IPADDY=$1

nwmgr | awk ‘!/hp_apa/{ printf “%s %s\n”, $1,$2 }’ | awk ‘/UP/{print $1}’ | while read -r LN
do

 sleep 1
 echo "The LAN is ${LN}"
 ifconfig ${LN} ${IPADDY} netmask 255.255.255.0 up > /dev/null
 ping ${IP2} -n 1 -m 5 > /dev/null
 rc=$?
 if [ $rc -eq 0 ]
 then
   echo "Success $LN as $IPADDY was able to ping $IP2"
 else
   echo "NO JOY $LN as $IPADDY was able NOT to ping $IP2"

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
Boot: lvol1 on: /dev/disk/disk2490_p2
Root: lvol3 on: /dev/disk/disk2490_p2
Swap: lvol2 on: /dev/disk/disk2490_p2
Dump: lvol2 on: /dev/disk/disk2490_p2, 0

lvlnboot: Volume group not activated.
Cannot display volume group “/dev/vgAP1”.

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.
