Hello,
If you clear the metadata of a drive it removes all data from the drive. Taking this step should only be done on drives that have not gone into a leftover state due to drive errors.
You will need to review your Event logs to determine why the drives went into a leftover state. If the drives had media errors, you will see Event messages from the drives stating the error type. UREs or Smart Trips are indications to never reuse that drive.
You should also be taking a back up of your data before performing any further troubleshooting on your own. Another option would be to purchase support from HPE for a limited time in order to recover your Vdisk. A log review is needed in order to recover your Vdisk without risking loss of data.
Cheers,
Shawn
