What happens when the descriptor and snapshot files do not match during snapshot consolidation in vCenter?

When the descriptor and snapshot files do not match during snapshot consolidation in vCenter, a warning is displayed in vCenter. This situation typically indicates some form of inconsistency or issue with the snapshot files, which can prevent proper handling of the snapshot. The system will alert the administrator through a warning message, allowing them to investigate the underlying issue further.

This warning serves a critical purpose; it informs the administrator that there could be potential data integrity risks or problems that could affect the virtual machine's performance or recovery options. It prompts the administrator to check the snapshot's status and take necessary actions to resolve the discrepancies.

Other options imply different levels of severity or outcomes of the mismatch. For instance, having an error message preventing consolidation would suggest a more critical halt in operations, while automatic deletion without user intervention may not be suitable due to the potential data loss. Not taking any action at all could leave the virtual environment vulnerable and unaware of issues that need resolution. Therefore, the correct approach involves notifying the administrator with a warning, thus allowing for a controlled response to the detected issue.
