StorageWorks Status Reporting
Each StorageWorks shelf identifies error conditions or failures caused by the
major shelf components, such as blowers, power supplies, or storage devices. This
status is displayed on either the power supply or the SBB light emitting diodes
(LEDS). In addition to the visual display, the shelf generates logic signals for
processing by the SCSI controller or the host. The following sections describe the
logic signals, their states and functions, and how to interpret the LED displays.
