Recently experienced data loss due to bad blocks on one LUN on our SAN, which was confirmed by our SAN vendor. As a result, when I attempt to download a vmdk from the affected datastore in the datastore browser I recieve the following error: Expected FILE_DATA message. Got: SESSION_COMPLETE.
The vmdk begins the copy process then fails shortly thereafter. In addition, a storage vmotion also fails with more specific error codes which basically indicate what was stated above regarding back blocks on the LUN.
Does anyone have any recommended tools or processes to retrieve the vmdk and avoid the bad blocks? I simply want to download the vmdk from the damaged datastore and upload it to a healthy one.
