Solution

Depending on your HANA revision level, you can use any of the method listed below. We manage to solve our issue by using the method number 2. It’s easy and simple.

Method 1

Step 1: Use hdbuserstore list to output all the existing KEY in the system.

 hdbuserstore list
DATA FILE       : /usr/sap/SID/home/.hdb/hostname/SSFS_HDB.DAT
KEY FILE        : /usr/sap/SID/home/.hdb/hostname/SSFS_HDB.KEY

KEY DEFAULT
  ENV : hostname:30015
  USER: SAPABAP1
KEY MONITOR
  ENV : hostname:30015
  USER: SAPMONITOR
KEY MAINTENANCE
  ENV : hostname:30015
  USER: SAPMAINTAIN

Step 2: If you see above output, it seems that someone has already created the DEFAULT KEY name in the system. You must use a different KEY name. Example, as below.

hdbuserstore -u SAPServiceSID SET NEW_KEY_NAME 
HANA_HOST:HANA_PORT SAPABAP1 PASSWORD

Method 2

Remove option -u and the username. Just execute below command,

hdbuserstore SET DEFAULT HANA_HOST:HANA_PORT SAPABAP1 PASSWORD
