- Red Hat Enterprise Linux 6 update 5
- SAP HANA
- SAP HANA Multi-Install option selected while installing using
- SAP HANA Multi host install fails with the message "LIBSSH2_ERROR_KEY_EXCHANGE_FAILURE , unable to exchange encryption keys"
The recommended way to install a Scale Out landscape is to use saphostagent as communication method.
Please refer to the SAP HANA Installation and Upgrade guide to set up saphostagent (with SSL encryption).
Components of the HANA installer are linked vs openssl-0.9.8 while liblibssh2 is linked against libcrypto.so.10 (openssl-1.0.1).
Using ssh as communication method leads to both libcrypto.so.6 and libcrypto.so.10 being loaded in the same namespace - as the two libraries are incompatible with each other the installer will fail exchanging the keys.
