1. for ((i=1; i<=64; i++)); do itadm create-target -n "iqn.1986-03.com.sun:02:$i"& done;

can crash kernel easily (test on different server and vm)
and if not, we have "transaction commit for provider_data_pg_iscsit failed - object already exists"

and historically I also have incoherence and corrupted stmf/smf store when simultaneous stmfadm command are used.
No pbls on stmf when smf store disable: "svccfg -s stmf setprop stmf_data/persist_method=none"

If you try the shell-script with "stmf_data/persist_method=none", server crash more easily

==== to reset conf and retry ====
stmfadm list-target | awk '{print $2}' | xargs -n 1 stmfadm offline-target
stmfadm list-target | awk '{print $2}' | xargs -n 1 itadm delete-target
