[SunRescue] SCSI question

[Martin Wedel]

Hello again.                                                          
   I have an external SCSI enclosure containing 2 2.8GB full-height's 
and 2 4x cd-roms. Active terminator. Connected to the external scsi2  
port on my 670's mainboard.  3 foot cable (new).

**the 'problem'                                                       
                                                                      
  The hdd activity leds blink at a constant rate (maybe 7-10 times a  
sec) and simultaneously whenever the system is running and hooked up  
to the scsi bus on the 670. Everything still seems to be working fine,
 with redhat 6.2 loaded and running dandy. The leds do indicate actual
drive activity properly, as i see the led indicate drive activity on  
the proper drive whenever i perform  disk operations.                 
                                                                      
Anyone have any idea what cuases this? Termination issue, etc?        
                                                                      
Thanks!!
