Tracking VBS operations

Each VBS start or stop operation is represented as a task consisting of one or more sub-tasks. The task keeps track of the progress of the operation, identifies failures, and also reports the status of the operation. It also tracks the time taken to complete the operation and marks the operation as failed if it exceeds the maximum permitted time. A sub-task represents an action performed on an individual tier. You can track the progress of the tasks using vbstask on the CLI. You can view up to last five tasks executed on each VBS.
