Huawei SAP HANA Appliance 2488H and 9008 V5 Cluster Installation Guide 14
Method 1: One-Click Uninstallation on the Master Node
When the communication among database nodes is normal and the database is intact, you can uninstall the database in one-click mode on the master node.
- Run the cd command to go to the database instance installation directory.
The database installation path is different from the database uninstallation path. The uninstallation path is the database instance installation path.
/hana/shared/S00/hdblcmin
- Run the ./hdbuninst command to uninstall the database.
