Pre-Patching Preparation
Review VMware patch release notes for relevant updates.
Verify the current version of VMware products in use.
Check compatibility of patches with existing infrastructure.
Notify stakeholders about scheduled maintenance windows.
Backup virtual machines and critical data.
Here are some additional steps that could be included in the Pre-Patching Preparation section of your VMware patching checklist
Ensure that all VMware tools are updated to the latest version
Confirm that the management and monitoring tools are compatible with the new patch
Review and update any related documentation or procedures affected by the patch
Identify and document any custom configurations or changes made to the environment
Conduct a risk assessment to determine potential impacts of the patch on services
Set up a rollback plan in case of issues during or after the patch deployment
Schedule a test run on a non-production environment if applicable
Verify network configurations and firewall settings that may impact patch deployment
Ensure adequate resources (CPU, memory, storage) for the patching process
Communicate with external partners or vendors if their services may be affected
Review and verify licensing requirements for the patches being applied
Create a checklist of dependencies that need to be addressed before patching
Environment Assessment
Assess current resource utilization and performance metrics.
Identify VMs that require patching based on criticality.
Document the configuration of VMs and hosts to be patched.
Review any existing open issues that may impact the patching process.
Certainly! Here are some additional steps that could be included in the Environment Assessment section of your VMware patching checklist
Evaluate the compatibility of existing applications and services with the new patches
Check for any hardware dependencies or requirements for the patches
Review the current backup status of VMs and ensure recent backups are available
Assess the network bandwidth and connectivity to ensure patching can be performed without issues
Identify any third-party tools or integrations that may be affected by the patching
Determine the current patch level of the VMs and hosts to understand the gap
Analyze the impact of patching on resource allocation and scheduling
Review security policies and compliance requirements related to patch management
Engage with stakeholders to gather insights on critical workloads and potential downtime windows
Identify any maintenance windows or scheduled outages that may coincide with the patching process
These additional steps will help ensure a comprehensive assessment of the environment before proceeding with patch deployment
Patch Testing
Create a test environment for patch deployment.
Apply patches to the test environment and monitor for issues.
Validate the functionality of applications and services post-patch.
Document any issues encountered during testing and resolutions.
Here are some additional steps that could be included in the Patch Testing section of your VMware patching checklist
Review the release notes of patches for known issues and compatibility concerns
Test rollbacks by simulating a failure scenario and reverting to the previous state
Conduct performance testing to ensure that the patched environment meets performance benchmarks
Involve key stakeholders in the testing phase to gather feedback on application performance and stability
Verify that security features and configurations remain intact post-patch
Test integration points with other systems and services to ensure continued interoperability
Run automated test scripts to check for regression issues in critical applications
Confirm that backup and restore procedures are functioning correctly after patches are applied
Schedule and perform a user acceptance testing (UAT) session to ensure business requirements are still met
Ensure logging and monitoring tools are functioning as expected after the patch deployment
Patch Deployment
Schedule patch deployment during off-peak hours.
Inform users about potential downtime during the deployment.
Execute the patch installation on the target VMware products.
Monitor the patching process for any errors or alerts.
Here are some additional steps you might consider including in the Patch Deployment section of your VMware patching checklist
Confirm the availability of backup systems and data prior to deployment
Review and apply any necessary pre-deployment configurations or settings
Validate that the target systems are in a healthy state before initiating the patch process
Ensure that sufficient resources (CPU, memory, disk) are available for the patching process
Document the version of the software prior to patching for reference
Implement rollback procedures in case of patch failure or issues post-deployment
Notify the IT team and stakeholders when the patch deployment begins
Track and log the patching process for future reference and compliance
Verify that all dependencies and prerequisites for the patches are met
Run automated scripts or tools to assist with the patch installation where applicable
Perform any necessary reboots after patch installation, if required by the patches
Confirm that the patches have been applied successfully by checking version numbers or logs
Update documentation and inventory records to reflect the new patch levels
Notify users and stakeholders once the deployment is complete and services are restored
Post-Patching Validation
Verify that patches have been successfully applied.
Check VM and host performance after patching.
Conduct functionality tests on critical applications and services.
Update documentation to reflect new patch levels.
Review and Reporting
Review the patching process for any lessons learned.
Report the outcomes of the patching process to stakeholders.
Schedule the next patch cycle based on vendor release schedules.
Ensure compliance with any regulatory requirements regarding patch management.
Here are some additional steps that could be included in the Review and Reporting section of your VMware patching checklist
Analyze the effectiveness of the patches applied and their impact on system performance
Document any issues encountered during the patching process, along with resolutions and recommendations
Update internal documentation and patch management policies based on the review outcomes
Gather feedback from team members involved in the patching process to identify areas for improvement
Review and update the risk assessment related to the newly patched systems
Compare the patching results against predefined success criteria to evaluate overall performance
Communicate any changes in system configurations or functionalities to relevant teams
Archive patching logs and reports for future reference and compliance audits
Review vendor communication for any upcoming patches or critical updates that may affect future patch cycles
Conduct a post-patching meeting with the team to discuss the review findings and next steps
