I have a alot of servers that have padded numerics in their names. Here's a quick way to issue SSH commands to all of them. The key is to use good old printf

for i in {1..10}; do ssh cloud-host-$(printf "%02d" $i) iscsiadm -m node -T iqn.2004-04.com.megastorage:hyper-zfs-serv:iscsi.zabbix.c4c655 -u; done
