Promise has identified a cosmetic facet in our VTrak Ex30 series if deployed with single controllers and partially populated bays. If any of the drive bays are left unpopulated, the indicator LEDs for these bays will blink intermittently. These indicators are supposed to be off (unlit) if there are no drives in the associated bays. The issue is completely cosmetic and is not associated with any functionality or stability problems. 

Note that this ONLY happens when running with a single controller in our E- Class RAID head system (does not impact expansion chassis). 

Event logging, snmp and email notification are fully functional.

Promise recommends to monitor and manage the enclosure via WebPam Pro or CLI (Command Line Interface).
