Hi Anna, do we need to check compatibility between target esxi and storage server ( os, firmware)
Hi Bro,
Yes, checking compatibility between your target ESXi (VMware vSphere Hypervisor) and your storage server (including its operating system and firmware) is essential. Ensuring compatibility helps prevent issues such as performance degradation, data corruption, and system instability. Here are the key areas to focus on:
1. Hardware Compatibility List (HCL):
- VMware maintains an HCL that lists supported hardware components, including storage devices. Verify that your storage server's hardware is on this list and is supported by the specific version of ESXi you plan to use.
2. Storage Controller and Firmware:
- Check if the storage controller firmware is supported by the ESXi version. Sometimes, storage controllers require specific firmware versions to work correctly with ESXi.
3. Drivers:
- Ensure that the correct drivers for your storage hardware are installed and compatible with your ESXi version. VMware provides a list of supported drivers for various hardware components.
4. Network Configuration:
- If your storage server is accessed over a network (e.g., iSCSI, NFS), verify that the network configuration and hardware (e.g., NICs, switches) are compatible with ESXi.
5. Storage Protocols:
- Ensure that the storage protocols (such as iSCSI, NFS, FC) used by your storage server are fully supported by the ESXi version. Check VMware's documentation for any protocol-specific requirements or limitations.
6. Multipathing and Failover:
- Verify the compatibility of multipathing software and settings between ESXi and the storage server. This is crucial for high availability and performance.
7. Storage Features and Functions:
- Some storage features (like deduplication, replication, snapshots) may require specific ESXi versions or additional configuration. Ensure these features are fully supported.
8. Compatibility Guides:
- Refer to VMware's interoperability matrices and compatibility guides. These resources provide detailed information on compatible configurations and supported versions.
To check compatibility, you can follow these steps:
1. Visit VMware's Compatibility Guide:
- Access the VMware Compatibility Guide (VCG) online and search for your specific hardware components and ESXi version.
2. Consult Vendor Documentation:
- Check the storage server vendor’s documentation and compatibility matrices for supported ESXi versions and configurations.
3. Firmware and Driver Updates:
- Ensure all firmware and drivers are up to date according to both VMware and the hardware vendor’s recommendations.
4. Testing:
- If possible, test the configuration in a non-production environment to validate compatibility and performance before deploying it in production.
By thoroughly checking compatibility, you can avoid potential issues and ensure a stable and efficient virtualization environment.
@@gnancloudgarage great support and explanation anna
@@gnancloudgarage hi anna, I have checked storage device it is compatible , and Esxi hpe host ( DL380) hba,nic cards are also compatible ( i/o).
Here the concern is firmware and drive upgrade ( we are using hpe customized OS)....
1. As checked present host running with 6.7u2 and firmware/ drivers of hba, nic are lower than the recommended with esxi8.
With above concern , HPE shared with spp bundle for firmware upgrade and shared driver links...as per this concern i have decided to below order
Host firmware upgrade -- Esxi upgrade --- if required driver upgrade.
But today checked with vmware engineer, he confirmed as u r going with customized iso, in this iso having firmware n drivers so 1st go with os upgrade and of required then go with firmware and drivers....
Anna can u plz make me clear on above concern
Sir why we deactivate HA in cluster when host is a member of cluster. pls ans
Hi Sir,
High Availability (HA) is a feature provided by VMware vSphere that helps ensure the availability of virtual machines (VMs) in the event of a host failure. When HA is enabled in a cluster, vSphere automatically monitors the health of ESXi hosts within the cluster. If an ESXi host fails, the VMs running on that host are automatically restarted on other healthy hosts in the cluster, thereby minimizing downtime.
However, there might be scenarios where you need to deactivate HA for a specific host in a cluster. Here are some reasons why you might want to do that:
1. **Maintenance or Upgrades**: When performing maintenance or upgrades on an ESXi host, it's common to temporarily disable HA for that specific host. This prevents HA from attempting to restart the VMs on other hosts while the maintenance is ongoing, which could lead to unnecessary VM migrations and potential disruptions.
2. **Resource Constraints**: If a particular host is experiencing resource constraints (e.g., low memory or CPU), disabling HA on that host can prevent VM restarts on other hosts, which could further exacerbate resource contention issues in the cluster.
3. **Special Configurations**: In some cases, you might have special configurations or specific requirements on a particular host that are not compatible with HA. Disabling HA on that host allows you to maintain the desired configuration without interference from the HA feature.
4. **Testing or Troubleshooting**: During testing or troubleshooting scenarios, you might want to isolate a specific host from HA behavior to observe its behavior independently.
When you deactivate HA for a specific host in a cluster, it's essential to understand the potential impact on the availability of VMs running on that host. If the host experiences a failure while HA is disabled, the VMs will not automatically restart on other hosts, and their availability will be affected until manual intervention takes place.
To deactivate HA for a specific host in a cluster, you can do the following:
1. Navigate to the vSphere Web Client or vSphere Client.
2. Select the cluster that contains the host.
3. Go to the "Configure" tab.
4. Under "Services," select "vSphere Availability."
5. Click "Edit."
6. Deselect the checkbox for the host you want to exclude from HA.
7. Click "OK" to save the changes.
Remember to re-enable HA for the host once the intended operation is complete or the special requirements are no longer applicable. Always exercise caution when making changes to the HA configuration, as it directly impacts the availability and resilience of your virtual infrastructure.
Why do we deactivate the HA feature in the cluster while patching the server?? is it mandatory to follow or we can skip
Deactivating High Availability (HA) when patching servers in a cluster is a best practice, but it's not always mandatory.
Here's why it's recommended and when you can consider skipping it:
Why Deactivate HA during Patching:
1. Resource Reservation:
When you apply patches or updates to a host, it might require a reboot. HA ensures that VMs are automatically restarted on other hosts in the cluster if a host fails. However, during a host reboot, there's a temporary resource shortage that can lead to performance issues. Deactivating HA reduces this risk.
2. VM Migrations:
Patching may involve VM migrations between hosts. HA might interfere with this process, potentially leading to resource contention or migration failures. Deactivating HA can make migrations smoother.
3. Avoiding False Alarms:
Patching often triggers alarms or false positives in HA, which can cause unnecessary VM migrations or failovers. Deactivating HA prevents these alarms and unnecessary VM movements.
When You Can Skip Deactivating HA:
1. Non-Disruptive Patches:
If you're applying patches that are known to be non-disruptive (e.g., they don't require host reboots), you may choose to leave HA enabled. However, always follow best practices recommended by your virtualization platform and patch management procedures.
2. Testing and Confidence:
If you have thoroughly tested the patches in a non-production environment and are confident in their stability, you might feel comfortable keeping HA enabled during the patching process.
3. Risk Tolerance:
The decision to deactivate HA depends on your organization's risk tolerance and the specific requirements of your infrastructure. Some organizations prioritize avoiding any potential disruptions during patching, while others may tolerate some temporary performance impacts.
In summary, while it's a best practice to deactivate HA during server patching to minimize potential disruptions, it's not always mandatory.
The decision should be based on factors like the nature of the patches, testing, and your organization's risk tolerance.
Always follow the recommendations and guidelines provided by your virtualization platform and consider the specific needs of your environment.
thanks a lot @@gnancloudgarage

is it mandatory step to follow during patching activity
step3: place in maintenance mode in the monitoring tool if yes how do we do that
Yes, it is recommended in the production environment to avoid false alerts during the scheduled maintenance window.
For example - SolarWinds Network Performance Monitoring (NPM) Tool
To place a server or node in maintenance mode in SolarWinds Network Performance Monitor (NPM), you can follow these steps:
1. Log In to the SolarWinds NPM Web Console:
Open a web browser and access your SolarWinds NPM web console by entering the URL or IP address of your SolarWinds server.
2. Navigate to the Node You Want to Place in Maintenance Mode:
Using the left navigation pane, browse to the specific node or server that you want to put in maintenance mode.
3. Select the Node:
Click on the node/server you wish to place in maintenance mode. This will usually take you to the Node Details page for that device.
4. Enter Maintenance Mode:
On the Node Details page, you should see an option or button for putting the node into maintenance mode. The location and appearance of this option can vary depending on your specific version of SolarWinds NPM, but it is typically labeled as "Maintenance Mode" or something similar.
5. Specify the Maintenance Period:
A dialog or form will likely appear, asking you to specify the duration of the maintenance mode. You can usually choose a start time and an end time for the maintenance period. Set the time frame during which you want the server to be in maintenance mode.
6. Confirm and Save:
After specifying the maintenance period, confirm the settings and save your changes. The server/node will now be in maintenance mode for the specified duration.
7. Monitor During Maintenance:
While the server/node is in maintenance mode, SolarWinds will typically suppress alerts and notifications related to that device. This allows you to perform maintenance or updates without generating unnecessary alerts.
8. End Maintenance Mode:
Once the maintenance period is over, SolarWinds NPM will automatically take the server/node out of maintenance mode, and normal monitoring and alerting will resume.
Please note that the exact steps and options may vary depending on the version of SolarWinds NPM you are using. If you are unsure about how to place a node in maintenance mode or cannot find the option, refer to the SolarWinds documentation or contact SolarWinds support for specific guidance related to your version of the software.
Thank you so much @@gnancloudgarage
@@gnancloudgarage Hi Sir, In the pre implementation step HA is already disable mode then how VMs migrated automatically when you have put host into maintenance mode..
@@mukeshb1536 Hi Sir,
Thanks for your question!
When you put a host into maintenance mode, VMs are migrated automatically using technologies like DRS (It uses VMotion), vMotion, which allows for seamless migration of VMs from one host to another without downtime.
Despite HA being disabled during the pre-implementation step, vMotion ensures that VMs can still be migrated to maintain availability.
and what is the difference between HPE one view and ILO
HPE iLO is a server-specific remote management tool, while HPE OneView is a comprehensive infrastructure management solution for the entire data center, offering centralized control and automation capabilities across servers, storage, and networking equipment
oh great thanks @@gnancloudgarage
