I think you may be conflating the array task with slurmstepd tasks.

Every array task does have it's own job id, usually <JOBID>_<TASKID>

It will also have a 'normal' job id that goes with that.

You can get detailed information from sacct if you have configured it. 
In fact, it also breaks things down into slurm steps, so you would be 
able to get pretty good detailed info.
