Cause

A change in the working location of the VxRail LCM upgrade components has caused this issue. There is an exception causing it to look for the file in the old location.Firmware in recent 7.0 codes: Old Location: /vmfs/volumes/<VSAN datastore>/upgradeBundles/ New Location: /vmfs/volumes/<VSAN datastore>/upgradeBundles-<VxRail cluster id>/

Resolution

This issue is addressed in VxRail Release 7.0.480 and later. This issue did not exist in the 8.0 VxRail code family.Workaround for earlier 7.0 VxRail code: Copy the relevant firmware files using the vCenter file datastore browser back to the old location: Old Location: /vmfs/volumes/<VSAN datastore>/upgradeBundles/ New Location: /vmfs/volumes/<VSAN datastore>/upgradeBundles-<VxRail cluster id>/ After the file is copied, the VxRail LCM upgrade can be retried or restarted and the file should be found correctly. Note: Should the folder /vmfs/volumes/<VSAN datastore>/upgradeBundles/ not exist, then it can be manually created on the VSAN datastore using the vCenter datastore file browsing page. If any assistance with these steps is required or something is not working as expected, open a Service Request with Dell Technical Support.
