Combine two commands in bash elif (FreeNAS)

I'm really sorry to annoy to you again with my problem but it seems I'm about to finish. My goal is to create a bash-script that checks if a IP-address is still online or a scrub is in progress and if not that my systems shuts down. My script, which is currently in use, looks like this

#!/bin/bash

hosts=(
  10.10.0.100 #Client 1
  10.10.0.101 #Client 2 
  10.10.0.102 #Client 3 
  10.10.0.103 #Client 4
  10.10.0.104 #Client 5
)

for host in "${hosts[@]}"; do
  if ping -c 1 -i 1 "$host" >/dev/null; then
    echo "No Shutdown - At least one PC ($host) is online"
    exit 0
  fi
done

echo "No PC is online - Shutdown"
bash shutdown -p now

I did some research and found the following command, to check if my scrub is in progress

if [ $(zpool status | grep 'scrub in progress') ]; then
    echo "No Shutdown - Scrub in progess"
    exit 0
  fi

But i have problems in combining these two. I want my script to first check the IPs and if they all are offline then check for a scrub before it shuts down the machine. So both if-cases have to be false (ips offline and scrub not in progress) but they should be processed chronological and if the first if-case returns a IP which is online the script should stop.

Maybe somebody can help me?
