I was just about to write my own PowerCLI script to update the timeout setting across multiple hosts/clusters when I ran across this post with the script already written. You saved me some time, thanks!


When I tried to Storage vMotion a VM to another LUN I got an “operation timed out error”:


After analyzing the vpxd.log, I found the following lines:


The best part I found out, is that the VM was rolled back to it’s old location without losing data or getting corrupt.

This problem is documented in KB1010045. The following solution will resolve the timeout problem:

Increase the Storage VMotion fsr.maxSwitchoverSeconds setting in the virtual machine configuration file to a larger value.

The default is 100 seconds.

To modify fsr.maxSwitchoverSeconds:

  1. Right-click the virtual machine and click Edit Settings.
  2. Click the Options > Advanced > General.
  3. Click Configuration Parameters.
  4. From the Configuration Parameters window, click Add Row.
  5. For the Name field,  fsr.maxSwitchoverSeconds and for the Value field enter the new timeout value.
  6. Click OK twice to save.
  7. Restart the virtual machine for the changes to take effect.
