PSM should expire eligible datasets, regardless of volume residency levels.

Have a look at the bottom few paragraphs here, specifically:

"Pass 1 of automatic primary space management
<https://www.ibm.com/support/knowledgecenter/SSLTBW_2.2.0/com.ibm.zos.v2r2.arcf000/pass1a.htm?view=kc#pass1a>
 (non-data-movement function in primary space management) and extent
reduction are performed for all volumes in storage groups defined with AM=Y
and AM=I (SG1, SG2, and SG3). Pass 2 of automatic primary space management
<https://www.ibm.com/support/knowledgecenter/SSLTBW_2.2.0/com.ibm.zos.v2r2.arcf000/pass2a.htm?view=kc#pass2a>
 (migration) is performed only for those volumes that are above the low
threshold after pass 1 and extent reduction have completed."

Have a look at the HSM log messages being produced for the datasets which
you expect to be expired.  They should indicate why they are not being
expired.
