Symptoms
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.
Impact
-- UCS load might fail.
-- Config save and load operations fail while the UCS load hangs. The failure of those operations may not be obvious, leaving the BIG-IP saved configuration different from the running configuration.
Conditions
-- A system that has ASM provisioned.
-- Loading a UCS file with an ASM configuration that comes from a different system.
Workaround
If you encounter this, run 'load sys config default' to de-provision ASM. The UCS file should then load successfully.
Note: If loading a UCS archive with the 'platform-migrate' argument, then there is no workaround. See: https://cdn.f5.com/product/bugtracker/ID990849.html
Fix Information
Loading UCS files no longer hangs if ASM is provisioned.
