Using the create_scaleup_snapshot utility application consistent and crash consistent storage snapshots can be created. The following behaviors should be noted when using this process.
- Application consistent storage snapshots are created for only the SAP HANA data volume.
- The storage snapshot will have the SAP HANA Backup ID appended to its name for recovery purposes.
- Crash consistent storage snapshots will add the data and log volume to a protection group with the instance system identifier (SID) appended for traceability purposes. If two systems with the same SID exist in the same landscape on the same FlashArray then Crash consistent storage snapshots should only be created of one of them.
- It is possible to create storage snapshots of SAP HANA virtual machines on VMware but only if the data and log volumes are located on a vVol datastore.
Only SAP HANA 2.0 deployments are supported for use with this utility. The utility will exclusively try to connect to the SystemDB.
