• Issue: Compatibility issues between Terraform v1.6 and older versions.
• Solution: We've addressed these issues, ensuring smooth operations.
• ⏰ terraform version on the deployer is upgraded to v1.6 to be aligned with the latest release. Look at the Additional Notes on upgrading the deployer.

3. IP Address Management

• Issue: Complicated IP address assignment affecting Ansible integration.
• Solution: We've improved the logic for gathering IP addresses by using IMDS, making it more straightforward to work with Ansible.

4. Enhanced Security

• Issue: Pipeline permissions for variable groups and agent pools needed improvement.
• Solution: Enhanced security by assigning proper pipeline permissions, ensuring a more secure environment.

5. Deployer Extension Behavior

• Issue: Deployer extension sometimes displayed unintended configuration details in logs.
• Solution: This issue is resolved, preventing configuration exposure in logs.

6. tfvars File Management

• Issue: Centralized storage of tfvars files was missing for command-line deployments.
• Solution: We now copy tfvars files into the Terraform state storage account, providing better control and organization.

7. Code Readability Enhancements

• Issue: General deployment and code readability needed improvement for both Ansible and Terraform.
• Solution: We've made various code readability enhancements, streamlining deployment and management processes.

Testing

All solutions and improvements have been tested using the SDAF deployment pipelines and the command line to ensure they work effectively.

Additional Notes

If you encounter difficulties upgrading the control plane VM, we recommend manually removing the configure_deployer extension from the VM and then redeploy.

Release 3.9.0.0

Overview

This release focuses on enhancements, bug fixes, and general stability improvements for SAP installation.

Problems Addressed

1. Lack of support for simple mount for SLES deployments.
2. Absence of support for susChkSrv for SLES HANA deployments. Note: susChkSrv extends the functionality of the main SAPHanaSR HA provider by executing a configurable action when a SAP HANA service is not running on a node.
3. Identified issues during runs:
   • When HANA database runs on ANF volumes, volumes are added to be managed by the pacemaker cluster.
   • Default values for "resource-stickiness" and "migration-threshold" are not set on the HANA cluster.
   • The timeout value of monitor operation for filesystem and ASCS/ERS resources differs from documentation.
   • ASCS/ERS profile changes are sometimes skipped.
4. Other general enhancements.

Solutions Implemented

1. Added new tasks under deploy/ansible/roles-sap/5.6-scsers-pacemaker to support simple mount for SLES deployments.
2. Updated 5.5.3-SAPHanaSR under deploy/ansible/roles-sap/5.5-hanadb-pacemaker to support susChkSrv for SLES HANA deployments.
3. Updated deploy/ansible/roles-sap/5.6-scsers-pacemaker to support the following:
   • Added support for resource-stickiness and migration-threshold for HANA cluster.
   • Added support for timeout value of monitor operation for filesystem and ASCS/ERS resources.
   • Added support for ASCS/ERS profile changes.
4. Updated deploy/ansible/roles-sap/5.5-hanadb-pacemaker to support the following:
   • Added support for resource-stickiness and migration-threshold for HANA cluster.
   • Added ANF volumes to pacemaker cluster.
5. Various files have been updated to support general stability improvements.

Testing

All changes have been tested using the SDAF deployment pipelines.
