sap_hana_install Installation testing

Installation testing is done by running: # run-sap_hana_install-install-tests.py <managed_node> <username> where managed_node is the hostname of the host on which SAP HANA installation testing will take place, and username is the name of a user for accessing the managed node. Some basic information is retrieved from the managed node via ssh, for which we need a user name.

The following steps have to be performed to prepare the tests:

  • The files mentioned in the tasks Copy ... to software directory (e.g. SAPCAR_1115-70006178.EXE), as well as their sha256 checksum files (e.g. SAPCAR_1115-70006178.EXE.sha256), need to be available in the directory specified by variable sap_hana_install_software_directory in file install-vars.yml, e.g. /software/sap_hana_install_test.
  • You can either download or copy these files manually or via Ansible with yml file prepare-install-tests-x86_64.yml or prepare-install-tests-ppc64le.yml. In that case, the required files need to be in a directory specified by variable software_host_directory, followed by the output of uname -m (e.g. /software/hana_store/x86_64), on a server specified by variable software_host.

For a SAP HANA scale-out test, the server(s) specified by variable sap_hana_install_addhosts in file run-install-test-03.yml (e.g. node02) need(s) to have the following file systems mounted from the node on which the test is run:

  • /hana/data
  • /hana/log
  • /hana/shared

Note: There should be no group named sapsys in file /etc/group on any of the test system(s), or if there is one, its group id should match the value of sap_hana_install_groupid (default 79) in file install-vars.yml.

Each test cycle is running the following steps:

  • ansible-playbook prepare-install-test-NN.yml -l managed_node
  • ansible-playbook run-install-test-NN.yml [...] -l managed_node -e [...]
  • ansible-playbook hana-uninstall.yml -l managed_node

All screen outputs are saved in a newly created directory with the following name pattern: hana-install-test-logs- + rhel_release + _ + hardware_architecture + _ + date_time_string

Example: hana-install-test-logs-8.4_x86_64_2022-03-06_23:29:34

For each of the tests, there will be three output files in the log directory (shown with example file names for the directory mentioned above):

  • hana-install-test-2022-03-06_23:29:34-prepare-01.log
  • hana-install-test-2022-03-06_23:29:34-run-01.log
  • hana-install-test-2022-03-06_23:29:34-uninstall-01.log

and an additional file name at the end of all tests, named

  • hana-install-test-2022-03-06_23:29:34-result.log

If the return code of a test is 0, the test has succeeded. If it is not 0 (default is 99), the test has failed.

A test succeeds if the string specified in variable expected_output_string for each test is found in the output of the test run.
