About this task
Topology Persist fails due to missing location code of a volume in the VIOS DB.
This problem often takes place after rebooting or upgrading VIO Servers.
Applies to
All BVQ Versions and PVM Systems
Procedure
The error message in the current_TopoPersist.log will look similar to the following:
LC is missing and volume is NOT an iSCSI volume

Solution
Note:
TopoPersist will fail as soon as it hits the first issue. This means, there might be more disks with the same issue that need to be fixed before persist of the data will be successful!
To find the problematic volumes and to fix the problem, please analyze the latest topology file which can be found here:
C:\ProgramData\SVA\BVQ\bvq-server\data\scanner-data\POWERVM\<scanner_name>\topology\error
or collect a full support package.
Next steps:
Unzip the topology file and open file de.sva.bvq.powervm.model.VirtualIOServer.json. This file shows the VIOS information collected from the HMC.
We recommend converting the JSON into a pretty print format in the editor of your choice, as this is way more human readable, than the single line JSON provided by the HMC API call.Search for the following statement: "locationCode": null. You will also find the volumeName close by
Scroll up in the JSON file until you find the name of the VIOS (“partitionName“) which the specific disk belongs to
Go to the affected VIOS system and run cfgmgr to re-check the configuration of the VIOS
Execute the script
on the VIOS.
Important: These are very profound changes! Only execute this script on HA tested Systems!Check with “lscfg -vl hdiskX” if the volume is now showing a location code.
Repeat the procedure for all affected VIOS.
As soon as all hdisks are fixed, the topo persist should succeed.
