CMD_PROTOCOL_ERR may be received from the Smart Array for any commands destined for an external RAID controller such as a P2000, or commands destined for tape drives or CD/DVD-ROM drives, if for instance a cable is disconnected. This mostly affects multipath configurations, as disconnecting a cable on a non-multipath configuration is not going to do anything good regardless of whether CMD_PROTOCOL_ERR is handled correctly or not. Not handling CMD_PROTOCOL_ERR correctly in a multipath configaration involving external RAID controllers may cause data corruption, so this is quite a serious bug. This bug should not normally cause a problem for direct attached disk storage. Signed-off-by: Stephen M.
