It's work good.

I have add this line to device in multipath.conf :
   path_grouping_policy "group_by_prio

That's not enough to run properly in active/passive mode with ALUA.
Mainly, because the default value of failback is "manual".

This is a minimal config to work flawlessly:
devices {
	device {
		vendor "COMPELNT"
		product "Compellent Vol"
		path_grouping_policy "group_by_prio"
		prio "alua"
		failback "immediate"
		no_path_retry 30
	}
}
