In test environments, it may be desirable to refresh the linked target with the original snapshot at some point. The refresh procedure is slightly different depending on whether the linked target device was resignatured or not. Both processes are included below.
When the linked target is resignatured, as recommended, and then refreshed, the new VMFS signature is overwritten. The datastore must be removed, and the linked target must not be in use during the relink procedure. The following steps should be used to ensure a clean refresh.
When the linked target is mounted with the same signature, a refresh of the linked target does not overwrite it. The datastore does not have to be deleted. There are two different procedures that can be used. The first ensures a clean refresh but takes longer. The second is quicker but has the potential to cause issues. Either is acceptable. The following are the recommended steps for a clean refresh.
The following steps provide a quicker refresh.
Some caveats around this procedure include:
It is possible that some other unforeseen event may occur, which is why the clean refresh is recommended.
