Fixed In:
12.0.0, 11.6.0 HF5, 11.5.2 HF1

Opened: Dec 14, 2014

Severity: 3-Major


Secondary blades requesting ASM sync "ASM is now entering sync recovery state. Requesting complete configuration from" noise in the logs, and needless sync work done. This issue does not affect enforcement or the actual sync state of the devices, it is just requesting extra synchronizations when they may not be needed.


Unnecessary sync events are created


Secondary blade restarts in unsynchronized mode.


Restarting the asm_config_server process on the secondary blade should alleviate the issue, but it may recur.

Fix Information

To optimize the system, DSC synchronization is no longer requested from secondary blades. This issue did not affect enforcement or the actual synchronization state of the devices.
