Issue
VS provisioning fails with the following error message:
Fatal: OnApp::Actions::Fatal Storage API Call failed: {"result"=>"FAILURE", "Error"=>"Error running lvchange: Volume group \"onapp-ujqdorcrruhycp\" not found\n Cannot process volume group onapp-ujqdorcrruhycp\n"}
Environment
OnApp version 5.x.x/6.x
Resolution
Follow the next steps to resolve the issue:
1. Check the connection of each compute resource running the command:
vgscan | grep ujqdorcrruhycp
2. You will see the results as in the example below.
============= 10.X.X.X
Found volume group "onapp-ujqdorcrruhycp" using metadata type lvm2
============= 10.X.X.X
Found volume group "onapp-ujqdorcrruhycp" using metadata type lvm2
============= 10.X.X.X
============= 10.X.X.X
============= 10.X.X.X
============= 10.X.X.X
Found volume group "onapp-ujqdorcrruhycp" using metadata type lvm
Those compute resources, which did not find the volume group, need reconnection.
3. Try to reconnect compute resources to Centralized Storage (SAN).
Cause
This generally occurs when the connection between one or more compute resources and Centralized Storage (SAN) is lost.
