After the management server has detected the lock on the Symmetrix storage system, it tries to access the storage system for 15 minutes and then logs the errors.
If you receive the error message, determine if someone is performing an operation that requires a lock, such as LUN mapping, LUN masking, or Discovery Data Collection. This also applies even if one of the processes is being used by a
