hello Sudhir,
I'm not very knowledgeable with HSM, however I can recommend either IBM Storage Insights (cloud) or IBM Spectrum Control (on prem) solutions.
https://www.ibm.com/products/analytics-driven-data-managementhttps://www.ibm.com/products/spectrum-controlIn both products you have the capability to monitor the A9000/A9000R devices, there is also powerful Reporting capabilities around Servers. Let met add a few screen captures here :
Host Connections
Volume mappings with more details on platform/ports/pools ..etc
then you can create easily a report from the panel :
or you can further combine the data into general groups (and other grouping structures) then make more complex reports if needed.
You can find a few good videos on youtube about Storage Insights on this channel :
