Symptoms
RDF/Metro array migration has migrated the data, however the WWN spoofing is still in place.
RDF/Metro Migration is a tool used to migrate data from one array to a new array.
AppSync tries to make a copy on the old VMAX array, using the LUN number from the new VMAX array.

AppSync tries to make a copy on the old VMAX array, using the LUN number from the new VMAX array.
Cause
The new VMAX array's serial number is not updated in the AppSync repository when the information about the source LUN is requested from SMI-S.
"inq.windowsamd64_exe -wwn" on the Source host is used to acquire the wwn of the source LUN.
In this example, we see the WWN:
This may run for a few hours. The output is in the TestSmiProvider.log file in the folder or directory where TestSMIProvider was run from. When the output is reviewed, you find one lengthy entry with the WWN acquired from "inq.windowsamd64_exe -wwn".
With a lot of the lengthy entry removed for readability, it lists as:

Note: An inq with no parameters still shows the LUN device ID as being on the "migrated from" VMAX array.
SMIS-S is then queried to get the proper array using the WWN above.
To manually query SMI-S, the following can be used:

To manually query SMI-S, the following can be used:
- Run TestSmiProvider on the SMIS-S and select the "ei" option
- Enter "CIM_StorageVolume" when prompted for the Class. This is case sensitive.
- Hit enter taking all the defaults for the other prompts.
This may run for a few hours. The output is in the TestSmiProvider.log file in the folder or directory where TestSMIProvider was run from. When the output is reviewed, you find one lengthy entry with the WWN acquired from "inq.windowsamd64_exe -wwn".

Instance 5494:
ObjectPath : Symm_StorageVolume.CreationClassName="Symm_StorageVolume",DeviceID="004FE",SystemCreationClassName="Symm_StorageSystem",SystemName="SYMMETRIX-+-000164200abc"
<PROPERTY NAME="SystemName" CLASSORIGIN="CIM_LogicalDevice" PROPAGATED="true" TYPE="string">

The xxx in the WWN may resemble the old VMAX array, however the Serial Number 000164200abc is the new VMAX array.
The cause is: AppSync is not updating the AppSync database with this serial number, resulting in AppSync attempting to make the copy on the "migrated from" array.
