Restarting the Appliance Kit Management Daemon (AKD) may impact data services continuity - several services will restart

Goal

Restarting the Appliance Kit Management Daemon (AKD) may impact data services continuity.

Several services will restart or refresh, possibly causing timeouts for client-side data access.

This only occurs on ak 2011, but it does not happen anymore on ak 2013 major release.

So that restarting akd on a machine running ak 2013 firmware does not impact data services.

NOTE: When akd is restarted on the 2013 code, it can be seen that Fibre Channel (FC) ports go down and back up when used in target mode and this can (and has) cause an interruption specifically with things like vmware.
