SAP Automation #

The following procedure demonstrates how to create a pillar structure for a system with SAP HANA, SAP NetWeaver, and with DRBD. This setup is based on SUSE Linux Enterprise Server for SAP Applications.

1. Install salt-minion package including dependencies using the zypper install salt-minion command.

   To install the package on SUSE Linux Enterprise 12, you must enable the Advanced System Management Module.

2. Make the correct version of SAP media available on a share, as it is required for running the formulas that install the SAP software. Ensure that the directories and files have correct permissions.

3. Install the Salt formulas using the sudo zypper in saphanabootstrap-formula sapnwbootstrap-formula drbd-formula habootstrap-formula command.

4. Create the pillar files structure.

   The pillar files work as configuration files for the Salt formulas and are intended as user input. To use the files, create a top.sls file which references other files you want to apply.

   1. Create the directory /srv/pillar and its subdirectories hana, netweaver, and drbd:

      # mkdir --parents /srv/pillar/{hana,netweaver,drbd}

      The directory names match with the names in the top.sls file (see next step).

   2. Create the file /srv/pillar/top.sls with the following content:

      base:
          'hana01,hana02':
              - hana.hana
              - hana.cluster
      
          'netweaver01,netweaver02':
              - netweaver.netweaver
              - netweaver.cluster
      
          'drbd01,drbd02':
              - drbd.drbd
              - drbd.cluster

5. Copy example pillar files to the appropriate directories:

   > sudo cp /usr/share/salt-formulas/metadata/hana/pillar.example /srv/pillar/hana/hana.sls
   > sudo cp /usr/share/salt-formulas/states/netweaver/pillar.example /srv/pillar/netweaver/netweaver.sls
   > sudo cp /usr/share/salt-formulas/metadata/drbd/pillar.example /srv/pillar/drdb/drdb.sls
   > sudo cp /usr/share/salt-formulas/metadata/cluster/pillar.example /srv/pillar/hana
   > sudo cp /usr/share/salt-formulas/metadata/cluster/pillar.example /srv/pillar/netweaver
   > sudo cp /usr/share/salt-formulas/metadata/cluster/pillar.example /srv/pillar/drdb

6. Modify the content of the pillar files for each Salt formula, according to the configuration you need.

   Notice that, in this example, we have three different cluster.sls files. Each might have different HA cluster requirements.

7. Create the file /srv/salt/top.sls with the following content:

   base:
       'hana01,hana02':
           - hana
           - cluster
   
       'netweaver01,netweaver02':
           - netweaver
           - cluster
   
       'drbd01,drbd02':
           - drbd
           - cluster

   In the above example, folder part is removed, as we are pointing to the formulas with their names.

8. Before proceeding to the next step, perform an environment check to ensure that all the required users and groups exist and configured correctly.

9. Execute Salt using the commands below. Keep in mind that these are example commands: Salt supports more options.

   • If you use a Salt Master with Salt clients, run:

     # salt '*' state.highstate

   • If you use only a Salt client, run:

     # salt --local state.highstate

   The command shows the result (green for everything is fine, red for errors).
