In fact, we have 6 production clusters running on SLES 15 sp but none of them are using the hook. SAPHanaSR-showAttr shows SFAIL for the replication status. But this output is read from the CIB where the replication attribute is set as 'SFAIL'  by pacemaker. I think, like you mentioned, the hook should be able to resolve it. I'll try this weekend. 
What I fail to understand is this error msg 'hanapopdb1-rsc_SAPHana_HPN_HDB00_monitor_60000:195 [ Error performing
operation: No such device or address]* Did you mean to trace the resource? If so, i'll be doing it this weekend

You can use pcs resource debug-start, but you have to shut it down before that.
Have you used some documentation for the setup ? Usually I reffer to the vendor's documentation. Go over it and check for a step that was not implemented.
RH's latest version is: https://access.redhat.com/sites/default/files/attachments/v10_ha_solution_for_sap_hana_scale_out_system_replication_0.pdf
https://access.redhat.com/articles/3004101

SLES:https://documentation.suse.com/sbp/all/html/SLES4SAP-hana-scaleOut-PerfOpt-15/index.html
https://documentation.suse.com/sbp/all/single-html/SLES4SAP-hana-sr-guide-PerfOpt-15/index.html
Based on my experience, the most critical component is the hook setup, so the cluster can properly identify replication status.
Also, unmanaged resources do not probe for replication status and thus the cluster never identifies if replication is restored until the resource is again 'managed'.
When removing maintenance, it's always nice to 'crm_simulate' . One very good article is https://www.suse.com/support/kb/doc/?id=000019158 .
What is the output of SAPHanaSR-showAttr ?
