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?

Annoying as all heck that sometimes the output is two line and sometimes one? I was forced to solve that problem today.

 

if [ “$OS” = “HP-UX” ]
then
   dcmd=bdf
fi

arraypointer=0

exec $dcmd | egrep -v “%used|/dev/deviceFileSystem” | awk ‘{lvn=$1;v=$2;if (v==””) {getline;cap=$1;ucap=$2;acap=$3;puse=$4;mp=$5;printf “%s %s %s %s %s %s\n”, lvn,cap,ucap,acap,puse,mp} else {printf “%s %s %s %s %s %s\n”, $1,$2,$3,$4,$5,$6} }’ | while read -r  p1 p2 p3 p4 p5 p6
do

   #### calculations

done

Typical bdf output:

/dev/vg00/lvol9    4096000 3140019  896285   78% /var/adm/crash
/dev/vg_stgb1/lvol1
1572765696 1382813225 178080447   89% /steven05stgb

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.

Spaces input by wordpress (thanks)

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.

09 Jun 10 System I/O layout (EMC specific)

This is a script designed to document the layout of a system. It is EMC specific and requires the output of the inq command, which I store in /tmp/inq.txt

It can however be adapted to non EMC disk systems. It correctly shows the port/lba layout and status of network and fiber I/O the way it appears on the outside of the system. Two tables are included to permit lookups of the port/lba information. It has worked on blades, and is certified for rp8420 and superdome systems.

It has only been tested on HP-UX 11.31.

… please stand by….update in progress…

26 Oct 09 HP-UX system update terminal session title bar

Nothing huge today.

I just wanted my HP-UX systems to udpate the title bar when Linux systems or Putty terminal sessions come in.

——–begin code——

NAME=”$(uname -n):${PWD}”
LEN=`echo “$NAME\c” | wc -c`
if [ “$TERM” = “xterm” ]
then
    PROMPT_COMMAND=”\033]0;${NAME}\007″
    echo $PROMPT_COMMAND
fi
——–end code———–

Tested with Putty. Will test later today with Linux.
