1Y0-312 Advanced Provisioning and Image Management Practice Question
Exhibit
Error Log: [PVS-STREAMING-001] Target device failed to connect to the PVS server. Reason: The vDisk is locked by a management operation. Current status: Merging.
Refer to the exhibit. An administrator attempts to boot a target device and receives the error shown. What is the cause of this failure?
⚠ Common exam trap
Candidates often mistake a vDisk merge error for standard network connectivity issues or file permission failures, overlooking the fact that active consolidation locks the vDisk files completely.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The vDisk is currently being merged, restricting access to target devices.
The error indicates that a background merge operation is currently being performed on the vDisk. When a merge is in progress, the vDisk is locked to ensure data integrity, preventing any target devices from booting until the operation completes. This is a standard safety feature to prevent corruption of the differencing disks while the PVS server consolidates the version chain into the base vDisk.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The target device account is locked in Active Directory.
Why it's wrong here
AD account lockouts prevent user authentication or machine trust verification but would not produce an error indicating a 'Merging' operation. The log specifically identifies the vDisk state as the source of the conflict, pointing toward server-side image maintenance rather than domain-level authentication or authorization failures for the device.
- ✓
The vDisk is currently being merged, restricting access to target devices.
Why this is correct
During the merge process, the vDisk is held in an exclusive lock state to consolidate differencing disks into the base image. This ensures no data is written to or read from the vDisk while the file structure is being restructured, making it unavailable for booting until the process finishes.
- ✗
The target device is attempting to use an incorrect BDM partition.
Why it's wrong here
Boot Device Manager (BDM) issues typically result in connectivity errors or inability to locate the PVS server IP address. The error explicitly references a server-side lock, which indicates that the connection reached the server, but the server rejected the boot request due to an ongoing administrative merge task.
- ✗
The PVS server lacks sufficient disk space for the write cache.
Why it's wrong here
Insufficient write cache space would generate a different error during the write-cache initialization phase, not a merge conflict error. Merge errors occur strictly when administrative tasks conflict with image availability, whereas write cache errors usually occur after the device has successfully established a connection and started streaming data.
