Symptoms

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.

Impact

System does not start up or has intermittent failures if running.

Conditions

This occurs when there are 10 CPUs allocated for ASM guests.

Workaround

Reduce the number of cores to 8 or increase the number to 12.

Fix Information

This release disables channel splitting/division when number of TMMs is not a supported number, so ASM guests work correctly.
