When attempting to start an OSA device, it fails with an EZZ4310I message reporting an 80103150 error code. This is especially likely for a new device, new processor, or the first time starting a new LPAR.
EZZ4310I ERROR: CODE=80103150 REPORTED ON DEVICE GIGOSA1. DIAGNOSTIC CODE: 03
DLC code xxxx3150 when trying to activate an OSA is because of the PORTNAME on the TRLE (which matches the name on the DEVICE statement or the PORTNAME value on the INTERFACE statement) is not the same as had already been used by another stack (probably on another LPAR) sharing this same OSA port. All systems sharing an OSA port have to be configured with the same PORTNAME.
Resolving the problem
Correct the TRLEs so that all LPARs on a CPC are referencing the OSA ports consistently.
If you do not think this is supposed to be sharing the port, then:
- Check the TRLE's device numbers (and how the IOGEN maps these to CHPIDs).
- If this is an OSA Express3, 4S, or 5S device with multiple ports per CHPID, then make sure the PORTNUM value on the TRLE is specified correctly.
