The TMM plugin manager does not expect/support an ASM guest configuration of 10 cores, thus its calculations as to the number of devices required and numbering does not match the existing number of threads/devices.
System does not start up or has intermittent failures if running.
This occurs when there are 10 CPUs allocated for ASM guests.
Reduce the number of cores to 8 or increase the number to 12.
This release disables channel splitting/division when number of TMMs is not a supported number, so ASM guests work correctly.
