Severity: 2-Critical


If a UCS file from a BIG-IP system running a different software version that also has an ASM configuration is loaded onto a device that already has ASM provisioned, the load may hang indefinitely.


UCS load might fail.


-- A system that has ASM provisioned. -- Loading a UCS file with an ASM configuration that comes from a different system.


If you encounter this, run 'load sys config default' and de-provision ASM. The UCS file should then load successfully.
