Bug ID 591857: 10-core vCMP guest with ASM may not pass traffic

Last Modified: Nov 07, 2022

Affected Product(s):
BIG-IP ASM(all modules)

Known Affected Versions:
11.6.0, 11.6.0 HF1, 11.6.0 HF2, 11.6.0 HF3, 11.6.0 HF4, 11.6.0 HF5, 11.6.0 HF6

Fixed In:
11.6.0 HF7

Opened: May 07, 2016

Severity: 1-Blocking


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 may not start or may exhibit intermittent failures.


11.6.0 HF6 ASM provisioned on a vCMP guest 10 CPU cores allocated to an ASM guest


Change the number of cores on the ASM guest to use either 8 CPU cores or 12 CPU cores.

Fix Information

This issue was partially fixed in 11.6.0 HF6, but the tmplugin RPM was incorrect. This fix includes the proper RPM.
