Asynchronous delay
All update operations from the writable cache filesets are on the primary gateway. Queues in the primary gateway are pushed to home asynchronously based on the afmAsyncDelay interval.
This interval can be modified by using the mmchfileset command. You can force a flush of all the pending updates without waiting for asynchronous delay by using the mmafmctl command with the flushPending option. The flushPending option can be set at the fileset or file system level, or with a file that contains the list of files to be flushed.
For more information, see mmafmctl command.
