• • Running the command "df -h" on the affected ESXi host will result in the same error message: "Cannot open volume"

Environment

VMware vSphere ESXi 7.0.x
VMware vSphere ESXi 8.0.x

Cause

Issue with datastore not being presented properly.

Resolution

• Make sure the presentation of the datastore from SAN is set for the ESXi host. Verify that the datastore shows up in the list of datastores and is accessible.
  
  
• Perform a rescan of the storage of the affected ESXi host
  Reference: Performing a rescan of the storage on an ESXi host
  
  
• Reattempt the upgrade. 
  
  
• If it fails, reboot the host and verify that the datastore is present by searching for it in the datastore list for the host.  Retry the upgrade if the datastore is presented properly or doesn't exist.
  
  
• After the upgrade, the datastore can be fixed either by being represented from the SAN storage and/or reconnected on the host.
