Unable to add host in an HANA system with "Unknown user and password combination"

880 Views

I installed one HANA system and would like to add hosts into it for scale out testing, but it always show the password is not correct after input <sid>adm password. The steps that I did to add the host like below.

Master node:

1. Install HANA system into a specified path.

2. Export this path with NFS to share to other hosts, the export access is (rw, no_root_squash), and the install directory is grant permission with 777.

3. Add all the hosts information into /etc/hosts file, and did same thing on all hosts. Both short and FQDN host name be added into /etc/hosts file.

Slaver node:

1. Create directory and mount it to shared HANA director, I can access all the HANA files in the mount point.

2. Run the hdblcm with root user to add host.

3. After input password for <sid>adm, it will wait for a moment and shows the "Unknown user and password combination" error.
