If the volume snapshot on FlashArray has been created correctly without issue, then it can be confirmed. If any issues have occurred SAP HANA needs to be told to abandon the data snapshot so that it is not listed as a valid recovery point.
To confirm the data snapshot execute the following:
BACKUP DATA FOR FULL SYSTEM CLOSE SNAPSHOT BACKUP_ID <External Backup ID> SUCCESSFUL;
To abandon the data snapshot execute the following:
BACKUP DATA FOR FULL SYSTEM CLOSE SNAPSHOT BACKUP_ID <Prepared database snapshot backup ID> UNSUCCESSFUL <additional comments>;
More information on SAP HANA Data Snapshots can be found in the SAP HANA Administration Guide for SAP HANA Platform.
