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.
