Dual VIOS env.: vhost-to-slot ID combination after LPM operation must be equal on both target VIOS

We use LPARS with DualVIO on Power Systems. We need to track Diskmappings to Hosts in Dokumentation, also need to add an delete disk mappings als Virtual Target Device on VIO for the LPAR.
At start we get 3 vhosts per LPAR in ascending order, the order is the same on borh VIOS.
If we use Live Partition Mobility (LPM), we always lose this order and in addidtion we get a different order on boith VIOS. This makes it more complex an increase human Error possibility. We want to keep a well documented and simple as possible Landscape.
Here is what happend:
In addition one more clarification (output from lsdev –slots) :

At Start:

SOURCE - VIO1
U8408.E8D.214810V-V1-C38 Virtual I/O Slot vhost6
U8408.E8D.214810V-V1-C39 Virtual I/O Slot vhost7
U8408.E8D.214810V-V1-C40 Virtual I/O Slot vhost8

SOURCE – VIO2
U8408.E8D.214810V-V1-C38 Virtual I/O Slot vhost6
U8408.E8D.214810V-V1-C39 Virtual I/O Slot vhost7
U8408.E8D.214810V-V1-C40 Virtual I/O Slot vhost8

After Live Partition Mobility to TARGET System

TARGET – VIO1
U8284.22A.21E150V-V1-C38 Virtual I/O Slot vhost6
U8284.22A.21E150V-V1-C39 Virtual I/O Slot vhost8
U8284.22A.21E150V-V1-C40 Virtual I/O Slot vhost7

TARGET – VIO2
U8284.22A.21E150V-V2-C38 Virtual I/O Slot vhost7
U8284.22A.21E150V-V2-C39 Virtual I/O Slot vhost6
U8284.22A.21E150V-V2-C40 Virtual I/O Slot vhost8

In conclusion – we would like to preserve the vhost configuration from the source VIO servers.

    The LPM feature to preserve virtual slot numbering across the LPM operations was added several years ago (p6 timeframe?). If the slot is available on the destination, it will be used / preserved, as well as the device name. Please resubmit if your seeing different behavior.

If you prefer that the LPM fail if the same slot is not available, then specify the slot number during LPM setup.
