need help on multipath

[rakesh boinapally]

we usually perform lot of multipath tasks in our company.

On a server if i want to configure multipath for disk aliases 

multipath -ll|egrep "dm-|size"|sed -e 's/\]/ /g'|sed -e 'N' -e 's/\n/ /'|awk '{print $6,$2}'|sed -e 's/\[size=//g'|sed -e 's/(//g'|sed -e 's/)//g'|sed -e 's/\.0G/G/'|sort  this displays output like below 

size=100G 360060e8007dd94000030dd940000048e

size=100G 360060e8007dd94000030dd940000048f

size=200G 360060e8007dd94000030dd940000048d

size=50G 360060e8007dd94000030dd9400000490

size=5G 360060e8007dd94000030dd9400000491

size=5G 360060e8007dd94000030dd9400000492

size=5G 360060e8007dd94000030dd9400000493

size=5G 360060e8007dd94000030dd9400000494

size=5G 360060e8007dd94000030dd9400000495

size=5G 360060e8007dd94000030dd9400000496

size=5G 360060e8007dd94000030dd9400000497

once we have this output we usually copy this output into file like allluns and run a script like below  test-create-multipath-conf.sh to

#!/usr/bin/ksh

> multipath.cfg

k=0

v=0

j=0

while  read line

do

line1=`echo $line|awk '{print $1}'`

line2=`echo $line|awk '{print $2}'`

if [ "$line1" = "size=100G" ];then

j=`expr $j + 1`

echo "        multipath {" >> multipath.cfg

echo "              wwid $line2" >> multipath.cfg

echo "              alias data$j" >> multipath.cfg

echo "        }" >> multipath.cfg

elif [ "$line1" = "size=5G" ];then

v=`expr $v + 1`

echo "        multipath {" >> multipath.cfg

echo "              wwid $line2" >> multipath.cfg

echo "              alias redo$v" >> multipath.cfg

echo "        }" >> multipath.cfg

elif [ "$line1" = "size=200G" ];then

k=`expr $k + 1`

echo "        multipath {" >> multipath.cfg

echo "              wwid $line2" >> multipath.cfg

echo "              alias fra$k" >> multipath.cfg

echo "        }" >> multipath.cfg

fi

done < allluns

sed -i '$i}' multipath.cfg

and it creates output like below 

        multipath {

              wwid 360060e8007dd94000030dd940000048e

              alias data1

        }

        multipath {

              wwid 360060e8007dd94000030dd940000048f

              alias data2

        }

        multipath {

              wwid 360060e8007dd94000030dd940000048d

              alias fra1

        }

        multipath {

              wwid 360060e8007dd94000030dd9400000491

              alias redo1

        }

        multipath {

              wwid 360060e8007dd94000030dd9400000492

              alias redo2

        }

        multipath {

              wwid 360060e8007dd94000030dd9400000493

              alias redo3

        }

        multipath {

              wwid 360060e8007dd94000030dd9400000494

              alias redo4

        }

        multipath {

              wwid 360060e8007dd94000030dd9400000495

              alias redo5

        }

        multipath {

              wwid 360060e8007dd94000030dd9400000496

              alias redo6

        }

        multipath {

              wwid 360060e8007dd94000030dd9400000497

              alias redo7

}

        }

To register output in a variable from a module in Ansible you have register:
https://docs.ansible.com/ansible/playbooks_variables.html#registered-variables

To create files in Ansible where you can use the variable you have the
template module.
