Article Content
Issue | When performing multi-node expansion from VxRail Manager the task fails with the following errors: In VxRail Manager GUI- X nodes out of Y failed at 'Registering hosts with the DVS ' task
- Failed:Registering ESXi hosts with Distributed Virtual Switch...
In vCenter Web Client- Cannot complete operation due to concurrent modification by another operation
- The object or the item referred to could not be found
The error does not happen with single node expansion. |
Cause | The VxRail code that creates the "reconfig spec" is not serialized so when multiple hosts are added, this can create a race condition and cause the process to fail. |
Resolution | To workaround the issue, simply retry the operation. |
