VxRail: Failed to collect vCenter log bundle due to log generation takes a long time
Summary: The full log bundle collection failed due to failed to download the vCenter log bundle.
Symptoms
Collect full log bundle by selecting all the components simultaneously from VxRail plugin UI Troubleshooting page, if the log collection takes more than 30 minutes, it may complete with an error message: Failed to download log bundle from url.
Check the log collected, other components' log have been collected successfully, except it failed to download the vCenter log bundle.

Cause
After VxRail manager triggers vCenter log bundle generation, the generated log bundle in vCenter will be deleted automatically after 30 minutes.
If for some reason, the entire log generation task takes longer time to complete, for example more components are selected together (VxRail manager, vCenter, ESXi, Platform, iDRAC), or some bundle size is too large and need longer time to collect, it may exceed the 30 minutes limitation. So the vCenter log bundle download task fails as the file is already deleted.
Resolution
The workaround to collect the vCenter log bundle:
Follow the VxRail plugin UI Troubleshooting page to collect the log bundle, but only select "vCenter" component to collect it separately.
