Creating SSP Logical Unit while partition inactive

Using the HMC 8.8.5 Enhanced GUI for creating a new SSP LU mapping to existing vhost Adapters (redundant on two VIOS) I got an error. Obviously the reason was that the LPAR was turned off. But the message does not mention anything about it.

Message: "The SSP Volume was created successfully, but could not be assigned to the Logical Partition. Please try again later."

Furthermore I would have expected that the mapping at the VIOS could be done even when the LPAR is turned of. After starting the LPAR the OS scan would detect the new LU anyway. This behaviour should be changed and the error message should be much clearer.

    As mentioned in the previous comment, creating SSP LU and attaching to a client partition in inactive state is supported. If you are running into problems while doing so, you can open a salesforce ticket and provide the logs foe debug.

    HMC does support assigning LU's to the partition when its inactive. However the VIOS which is part of the SSP cluster needs to have an active rmc connection to be able to create the LU & create the mapping. So if the VIOS has an active rmc connection, the failure could be because of a different reason and we would need the logs to check why the operation failed.
