However, it's important to address the low memory situation to ensure a smooth upgrade process. You might want to investigate the cause of the low memory alert and take appropriate actions, such as adding more memory to the vCenter server or optimizing existing resources. Once you've addressed the memory issue, you should be able to proceed with the upgrade without any problems. Hope this helps!
Need advise. We've completed stage 1 without any issues but when starting stage 2 we're getting below error, any idea what's causing this error? Pre-upgrade check failed due to the following problem: Error in method invocation [digital envelope routines] unsupported Thanks.
Hi, Thank you for your question The error "Error in method invocation [digital envelope routines] unsupported" typically points to an issue with SSL/TLS libraries or certificates used during the upgrade process. Here are some steps you can follow to resolve the issue: 1. Verify Certificate Settings: - Check if the vCenter Server certificate is valid and not expired. - If you are using custom certificates, ensure they comply with VMware's requirements for SSL/TLS during the upgrade. 2. Check vCenter Server Connectivity: - Ensure the source and target vCenter Servers have a stable connection and that there are no firewall or network issues. 3. Update ESXi Hosts: - Verify that the ESXi hosts managed by the vCenter Server are updated and compatible with the vCenter Server version you’re upgrading to (8.0 U2). 4. Review VMware KB Articles: - Refer to VMware Knowledge Base for similar issues. A relevant article might provide specific guidance. - Search for known bugs related to OpenSSL or TLS during the upgrade. 5. Log Analysis: - Review the pre-upgrade logs located in the `/var/log/installer` directory for more detailed information about the error. - Look for specific error codes or unsupported configurations that could be causing this. 6. Workaround for Unsupported Ciphers: - If the issue relates to unsupported cryptographic algorithms, consider updating OpenSSL or regenerating certificates to align with supported standards. 7. Retry the Upgrade: - Restart the vCenter upgrade process from Stage 2, ensuring all prerequisites are met and that the target deployment size matches the source. If none of these steps resolve the issue, I recommend reaching out to VMware Support with the error details and logs. They can provide tailored assistance based on your environment.
Thanks for the great explanation sir.. just wonder, what happen on old vcenter7 after doing this upgrade, will it be deleted or just power off in the host..?
Hi Sir, Yes it will. The old vCenter Server is powered off but not deleted. It is retained on the host in a powered-off state, allowing you to start it again if needed (for rollback purposes or additional verification Thank you

@@eddielui2134 Hi Eddie, Thank you for your question! If you want to keep using the old VM name, IP address, and hostname for your vCenter, here's how you can approach it: 1. Before Deployment: - Rename the Old vCenter VM: Before deploying vCenter 8, you can rename the old vCenter VM to something like "vCenter-old" to free up the original name. - Deployment: During the deployment of the new vCenter 8, specify the original vCenter VM name, IP address, and hostname. 2. After Deployment: - Verification: Once the new vCenter 8 deployment is complete and everything is working correctly, ensure all services and connections are stable. - Final Adjustments: If needed, you can make any final adjustments to the new vCenter configuration. By renaming the old vCenter VM before the deployment, you avoid potential conflicts and ensure a smoother transition.
Not exactly. The new name is temporary and will only be used during the upgrade process. Once the vCenter upgrade is complete, it will revert to the original name.
@Hi Gnan- What will happen to the hosts attached to vCenter if we go upgrade to VCSA 8.0 u2? Do we need to put Vcsa appliance in maintenance mode and move the hosts those are attached to it before the upgradation.
Hi Shahid, When upgrading to VCSA 8.0 U2, you generally do not need to put the VCSA appliance into maintenance mode or move the hosts attached to it. The upgrade process is designed to be non-disruptive to the hosts and the virtual machines running on them. Here are a few key points to keep in mind: 1. Backup: Always take a backup of your VCSA appliance before starting the upgrade process. 2. Pre-Check: VMware provides a pre-upgrade check which will help identify any potential issues that might affect the upgrade process. 3. Upgrade Process: The hosts managed by vCenter will remain operational during the upgrade. The vCenter server will be temporarily unavailable while the upgrade is in progress, but the hosts and VMs will continue to run without interruption. 4. Post-Upgrade: Once the upgrade is complete, the hosts will reconnect to the upgraded VCSA appliance automatically. For detailed steps and any specific considerations, you can refer to the official VMware documentation
Hi Bala, If We are upgrading vCenter, it's generally recommended to retain the same IP address for consistency, especially if other systems and services are integrated with it. Thank you
Hi Sir, excellent video. can you please tell how to find the exact vm which is not used by user for long time. through Vcenter or esxi host...user who have not logged into the VM for long time more than 30 days or 60days . need a help from you sir
Hi Sir, Certainly! VMware Aria Operations (formerly vRealize Operations Manager or vROps) is a robust tool for managing virtualized environments. Here's how you can use it to identify VMs that haven't been accessed by users for a specified period: 1. Access Aria Operations (AO) : Log in to your Aria Operations instance. 2. Navigate to VMs: Look for a section or tab that displays information about virtual machines (VMs) in your environment. 3. View VM Usage Metrics: AO provides various metrics related to VM usage and activity. Look for metrics such as "User Logins" or "Last User Login Time". 4. Filter VMs: Apply filters to narrow down the VMs based on their last user login time. You can specify a timeframe of more than 30 or 60 days to identify inactive VMs. 5. Identify Inactive VMs: Review the list of VMs to identify those that have not been accessed by users for the specified period. 6. Take Action: Based on your analysis, you can decide what action to take for each VM. This might include notifying users, decommissioning VMs, or further investigation. Using Aria Operations provides you with insights into VM usage and activity, allowing you to efficiently manage your virtualized environment and identify inactive VMs. Thank you
Hi , Thank you for your comment! If you’re stuck on the Validating step during the vCenter upgrade, here are some additional checks you can perform: 1. Verify Network Configuration: - Ensure that the source vCenter and the target deployment have proper forward and reverse DNS lookups configured. Use the following commands to check: nslookup nslookup - Confirm that the network gateway is reachable from the vCenter Server. 2. Check NTP Configuration: - Ensure that both the source vCenter and ESXi hosts have the correct time synchronization via NTP. Mismatched time can cause validation to fail. 3. Verify SSL Certificates: - Check if the SSL certificates of your vCenter are valid and not expired. Self-signed or expired certificates can sometimes cause validation issues. 4. Storage and Disk Space: - Ensure sufficient disk space is available on the source vCenter for staging the upgrade. Check `/storage` partitions if you're using VCSA. 5. Review Logs: - Check the `/var/log/installer/` directory on the source vCenter for detailed validation logs. Look for specific errors that could indicate the issue. 6. Firewall Rules: - Confirm that no firewall rules are blocking communication between the source vCenter, target deployment, and any DNS servers. 7. Unsupported Plugins: - Disable or remove any third-party plugins in the vCenter before initiating the upgrade, as unsupported plugins can lead to validation errors.
Hi. I opened a case with VMware and it was to do with not using the iso from under our entitlement. I was using generic iso for VCSA and getting stuck on validation. Once I downloaded the iso from my entitlement page it worked well.
Hi, Thank you for your question! The upgrade process shown in this video applies to both internal vCenter integrated with VxRail and external standalone vCenter Servers, with some considerations: For VxRail-integrated vCenter, you should always follow the VxRail upgrade path and guidelines provided by Dell, as the vCenter upgrade is part of the VxRail bundle. Make sure to check the Dell EMC VxRail Release Notes for compatibility. For external vCenter, you can directly follow the steps outlined in the video, ensuring prerequisites are met
Hi , Yes, it is possible to deploy the upgraded VCSA on the same ESXi host where the old VCSA is currently deployed. However, there are a few considerations to keep in mind: Resource Availability: Ensure the ESXi host has sufficient resources (CPU, memory, and storage) to accommodate both the old and the new VCSA during the upgrade process. Temporary Network Requirements: During the upgrade, both the old and new VCSA instances need to run concurrently. Ensure there are no IP or DNS conflicts. Storage Location: Verify that the datastore on the ESXi host has enough free space for the new VCSA appliance and its temporary data during the upgrade. Downtime Impact: Plan for minimal downtime, as the process involves switching services from the old VCSA to the new one. Once the upgrade is complete and validated, the old VCSA can be safely powered down and removed.
Regarding the order of upgrade, it's generally recommended to upgrade vCenter Server before upgrading ESXi hosts. This ensures that the vCenter version is compatible with the new ESXi version and helps in managing the upgrade process smoothly. Before upgrading, it's important to take a few precautions: 1. Backup: Ensure you have a recent backup of your vCenter and ESXi configurations and any critical data. 2. Compatibility Check: Verify that all hardware and software components are compatible with the new version. 3. Read Release Notes: Review the release notes for both vCenter and ESXi to understand any potential issues or prerequisites. 4. Test Environment: If possible, perform the upgrade in a test environment first to identify any potential issues. 5. Communication: Notify stakeholders about the upgrade plan and potential downtime.
Yes, you can rename the inventory name of the old vCenter Server before upgrading it, and then reuse the same inventory name for the new vCenter Server. Here’s a step-by-step guide on how to do it: ### Steps to Rename the Old vCenter Server 1. Log in to vSphere Client: Log in to the vSphere Client using the vCenter Server's administrator credentials. 2. Navigate to vCenter Server Settings: - Go to the "Hosts and Clusters" view. - In the left pane, select the vCenter Server you want to rename. 3. Edit Inventory Name: - Right-click on the vCenter Server. - Select "Rename" from the context menu. - Enter the new inventory name for the old vCenter Server (e.g., append "-old" or "-backup" to the name). - Click "OK" to save the changes. ### Upgrade and Reuse the Same Inventory Name 1. Upgrade the vCenter Server: - Follow the standard upgrade procedure for your vCenter Server, which might involve deploying a new vCenter Server Appliance (VCSA) and migrating the configuration and data from the old server to the new one. 2. Rename the New vCenter Server: - After the new vCenter Server is up and running, you can rename it to the desired name (the original name of the old vCenter Server) using the same steps mentioned above. - Right-click on the new vCenter Server. - Select "Rename" and enter the desired inventory name. - Click "OK" to apply the changes. ### Important Considerations - DNS and Network Configuration: Ensure that the DNS records are properly updated if the FQDN (Fully Qualified Domain Name) or IP address of the vCenter Server changes during the upgrade. This is critical for ensuring that ESXi hosts and other services can correctly resolve and communicate with the vCenter Server. - Backup: Always take a complete backup of the vCenter Server before making any changes. This includes both configuration and database backups. - Certificates: If your environment uses custom SSL certificates, ensure that the certificates are updated and correctly applied to the new vCenter Server. - Consistency: Ensure that all references to the old vCenter Server name in scripts, monitoring tools, and other integrations are updated to avoid any disruptions.
