Ansible - Update multipath.conf file

Hello There!
I have lot of servers that use multipath.
e.g.
Code:multipath {
wwid 369834349802938746554637382920111
alias asm_disk1
}
multipath {
wwid 369834349802938746554637382920112
alias asm_disk2
}I want an ansible playbook that add new entries for me. But it is not working right now. (new multipath entry inside a multipath entry)
Code:multipath {
# BEGIN ANSIBLE MANAGED BLOCK
multipath {
wwid 369834349802938746554637382920113
alias asm_disk3
}
# END ANSIBLE MANAGED BLOCK
wwid 369834349802938746554637382920112
alias asm_disk2
}This is my playbook. any ideas how to fix it?
