Is your VM migration failing with the error message "Operation is not allowed in the current state"? Learn how to identify and resolve the issue – step by step!
The error message "Operation is not allowed in the current state" can cause significant issues during the migration of virtual machines (VMs). It indicates that the VM or host is in a state that prevents the requested operation. This can be due to various reasons, ranging from pending tasks to incompatibilities between the systems involved. In this article, we provide you with a comprehensive guide to identifying and resolving the causes of this error, ensuring that your VM migrations proceed smoothly.
The error often occurs in various scenarios, including vMotion migrations, where a VM is moved between hosts without any operational interruption. It can also occur with Veeam Backup & Replication jobs, used for backing up and restoring VMs, if, for example, snapshots cannot be created. Another scenario is with Azure Spot VMs, where the error can arise due to capacity issues or bid price exceedances. To effectively address these problems, it is important to understand the specific contexts in which they arise.
At GoMovin, we understand how crucial the smooth operation of your IT infrastructure is. Therefore, we support you with our expertise and services in optimising your virtual environment. With our support, you can ensure that your VM migrations are efficient and free from unexpected interruptions. In the next section, we will take a closer look at the various causes of this error.
Optimise VM migrations by analysing VM and host health issues
To effectively resolve the error "Operation is not allowed in the current state", it's crucial to understand the underlying causes. These can be found in various areas, including issues with the VM state, host-related problems, network and storage issues, as well as resource conflicts. A systematic analysis of these areas will help you accurately pinpoint the source of the error and take targeted measures.
VM State Issues
A common reason for the error is VM state issues. This can occur if the VM is in a transitional state, for instance, during shutdown or a Storage vMotion. An inconsistent VM state in the vCenter Server can also lead to this problem. It's important to check the current state of the VM and ensure that there are no pending operations that could hinder the move.
Host-related Issues
Host-related issues can also be the cause. If the ESXi host is in maintenance mode, certain operations are not permitted. Problems with the management agents of the host (hostd, vpxa) can also cause errors. Incompatibilities between the ESXi versions of source and target hosts are another possible reason. It is thus advisable to compare the ESXi versions and, if necessary, perform an upgrade as described in the Veeam Knowledge Base article.
Network and Storage Issues
Network and storage issues can also play a role. Connectivity issues between hosts and vCenter or inaccessible VM files (due to storage problems) can cause the error. Ensure all network connections are stable and that VM files are properly accessible.
Resource Conflicts and Locks
Finally, resource conflicts and locks can prevent the migration. Pending tasks that block the migration or locks on VM files are typical examples. Check for any pending tasks and cancel them if necessary. Also, ensure there are no locks on the VM files that prevent access.
Accelerate VM migrations through structured troubleshooting, step by step
After identifying the possible causes, it is important to proceed systematically to rectify the error. The following solutions provide you with a step-by-step guide to resolve the issue and successfully complete your VM migration.
Review and Clean Up Tasks
Start with reviewing and cleaning up tasks. Cancel any existing tasks in the vSphere Client to avoid potential conflicts. Ensure all pending tasks are completed before proceeding. This can help eliminate resource conflicts causing the error.
Restart Services
Another crucial step is to restart services. Restart the vCenter Server service (vmware-vpxd) to address possible service-level issues. Also, restart the management agents on the ESXi host (hostd, vpxa) to tackle host-specific problems. However, consider the notes in the Broadcom Knowledge Base article regarding potential impacts.
Host Connection and Configuration Changes
Make host connection and configuration changes. Disconnect the host from the vCenter Server and reconnect it to refresh the connection and resolve status errors. Ensure the host is powered on, and restart it if necessary.
VM-Specific Actions
Take VM-specific actions. Remove the VM from inventory and re-add it to resolve potential inconsistencies. Reload the VM's .vmx file to restore host access. These measures can help update the VM state and resolve the error.
Azure Spot VM-Specific Solutions
If you are using Azure Spot VMs, check the Azure Activity Log for detailed error messages. Adjust the maximum bid price for Spot VMs to ensure it is not below the current spot price. Check the capacity and, if necessary, test other VM types. These steps can help resolve issues related to Azure Spot VMs, as described in the Microsoft Learn article.
Precisely resolve Veeam Backup & Replication errors through snapshot analysis
If the error is related to Veeam Backup & Replication, it's important to focus on snapshot issues. Veeam uses snapshots to back up VMs, and if a snapshot creation fails, it can lead to the error "Operation is not allowed in the current state". Therefore, a detailed analysis of snapshot creation is essential.
Identifying Snapshot Issues
Start by identifying snapshot issues. Check the Veeam logs (Task..log) for `InvalidState` errors that indicate problems with snapshot creation. Manually test the creation of a VM snapshot in vSphere to determine if the issue lies at the vSphere level. This will help you narrow down the source of the error.
Resolving Snapshot Issues in vSphere
Once you've identified snapshot issues, focus on resolving snapshot issues in vSphere. Ensure the VM is not in an invalid state, such as when shutting down. Fix issues with Storage vMotion or attached PCI devices that could affect snapshot creation. Once you've resolved the snapshot issues in vSphere, Veeam jobs should run smoothly.
Our experts at GoMovin are happy to assist you in analysing your Veeam environment and resolving snapshot issues. We help you optimise your backup and replication processes to ensure your VMs are reliably backed up.
Effectively Minimising ESXi Incompatibilities through Upgrade Strategies
Incompatibilities between ESXi versions can also lead to the error "Operation is not allowed in the current state." This often occurs when you attempt to migrate a VM from a host with a newer ESXi version to one with an older version. To avoid these issues, it's important to check the compatibility of the ESXi versions and take appropriate action.
Identifying Compatibility Issues
Begin with identifying compatibility issues. Check the hardware version (compatibility level) of the VM to determine if it is compatible with the ESXi version of the target host. Compare the ESXi versions of the source and target host to identify any incompatibilities. You can find compatibility information in the VMware documentation.
Solution Strategies
There are various solution strategies to resolve compatibility issues. One option is to upgrade the target ESXi host to a newer version to ensure compatibility with the VM. Another option is to reconfigure the job to a compatible host. As a last resort, you can downgrade the VM compatibility level, but this should be done with caution as it can lead to restrictions on VM functionality.
Efficiently solve VM issues using advanced tools and techniques
For advanced users, there are a number of advanced troubleshooting techniques and tools that can be helpful in resolving the error "Operation is not allowed in the current state." These techniques require a deeper understanding of the VMware infrastructure but can be very effective in diagnosing and resolving complex issues.
Using Command Line Tools
Using command line tools like `vim-cmd` allows you to control VMs (e.g., Power On, Reload .vmx) directly via the command line. This can be useful if the GUI is unresponsive or if you want to automate specific operations. However, using `vim-cmd` requires experience with the VMware command line.
Checking VM Connection Status
The checking of the VM connection status by examining the `Runtime.ConnectionState` property of the VM can reveal whether the VM is in an invalid or inaccessible state. This can be helpful in diagnosing connection issues. The `Runtime.ConnectionState` property can be retrieved via PowerCLI or the vSphere API.
Analysis of Log Files
The analysis of log files, especially searching through ESXi host logs for error messages, can provide valuable information about the cause of the error. The log files contain detailed information about the operations being performed on the host and can provide clues on errors or warnings. However, analyzing log files requires experience in interpreting VMware log messages.
Our experienced consultants at GoMovin are happy to assist you in applying these advanced techniques. We help you optimize your VMware environment and ensure that your VMs run smoothly.
Avoid VM errors through preventive measures and best practices
In addition to reactive troubleshooting, it is important to take preventive measures to minimise the occurrence of the error "Operation is not allowed in the current state."
