How to check and change hdisk attributes on AIX LPAR using script.

Today I am sharing script to change disk attributes using script.

precheck

Create directory with name aix_automation

#mkdir aix_automation

#cd aix_automation

Inside this directory create file with name list_hdisk

#touch list_hdisk

#vi list_hdisk

hdisk10

hdisk11

hdisk12

hdisk13

hdisk14

Add hdisk name in this file and save it .

#for i in 'cat list_hdisk'

do

echo $i

chdev -l $i -a algorithm=round_robin -a reserve_policy=no_reserve

sleep 2

lsattr -El $i |egrep -i 'algorithm | reserve_policy'

done

Using this simple script AIX admin can change and display multiple attributes and display.

Thanks !!!
