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
}
}
can any one help me with above requirement im trying to convert into
