You may encounter an error during the Failover Cluster Manager logon due to a lack of network connectivity. When checking the event log file, we noticed Error 1460 and it says the Cluster shared volume is no longer accessible. In this post, we will talk about this issue and see what you can do to resolve it.
Cluster Shared Volume is no longer accessible from this cluster because of error ‘(1460)’.
What are Cluster Shared Volumes in Windows Server?
Cluster Shared Volumes is a feature of Failover Clustering in Windows Server for use with Hyper-V. This allows a virtual machine complete mobility throughout the cluster.
Error 1460, Cluster Shared Volume is no longer accessible
If you encounter error 1460 and the cluster shared volume is no longer accessible on a Windows computer, follow the solutions mentioned below.
- Check ISCSI connection
- Make sure that Storage and network connection are fine
- Install all the required protocols
- Remove the Clustered Shared Volume and attach it again
Let us talk about them in detail.
1] Check ISCSI connection
ISCSI enables the creation of a shared storage network, allowing multiple servers and clients to access central storage resources as if the storage were a locally connected device. If the ISCSI connection is not working, you will encounter the issue in question. So, we recommend you go ahead and check the connection and make sure it is working fine.
2] Make sure that Storage and network connection are fine
Next up, we need to ensure that there is no issue with the Storage and Network connections. You also need to update the Network drivers as well as all other drivers including the Storage driver to get it working. Also, update the network or fiber switches to the latest firmware as well as their security protocols.
3] Install all the required protocols
When setting up a connection for the Failover Cluster Manager, we need to ensure that the network device has access to the Client for Microsoft Networks, File, and Printer Sharing for Microsoft Networks protocols. To install them, you can go through the guide given below.
- Open Control Panel.
- Click on Network & internet.
- Then, go to the Network & sharing center and click on the link of your connection placed right next to “Connections”.
- Now, click on Properties.
- Look for Client for Microsoft Networks, File, and Printer Sharing for Microsoft Networks, and enable them.
Once done, check if the issue is resolved.
4] Remove the Clustered Shared Volume and attach it again
If all else fails, our last resort is to remove the CSV volume from the Failover Cluster Manager and add it again. To do that, find the volume under Storage > Disk, right-click on the disk you want to remove and select Offline, and then again right-click on the disk and select Remove from Cluster Shared Volume.
After removing the volume, go ahead and add it again. Hopefully, this time you will not encounter the same problem.
That’s it!
