[. . . ] HP StorageWorks Modular Smart Array 30 (Formerly HP StorageWorks Model 4400 Family of Ultra320 SCSI Disk Enclosures) User Guide November 2003 (Second Edition) Part Number 335900-002 © 2003 Hewlett-Packard Development Company, L. P. The information contained herein is subject to change without notice. The only warranties for HP products and services are set forth in the express warranty statements accompanying such products and services. Nothing herein should be construed as constituting an additional warranty. [. . . ] For complete power redundancy, each power supply unit should be connected to a separate AC power source. 4. Confirm that the system components are all functioning normally by observing the condition of their status LEDs, as described in the next section. HP StorageWorks Modular Smart Array 30 User Guide 2-7 Installing the System in a Rack Verifying Normal Operation System LEDs The LEDs on the front of the system in the lower right corner summarize the overall status of all the system components. Figure 2-1: System LEDs Item 1 2 3 Color Green Green Amber Description Status (heartbeat) Power Fault Normal State Blinking On Off Power Supply Assembly LED The green LED on the power supply assembly is illuminated when both the power supply unit and the blower are operational. If there is a fault in the power supply unit or blower, this LED and the Power LED on the system are not illuminated. 2-8 HP StorageWorks Modular Smart Array 30 User Guide Installing the System in a Rack I/O Module LEDs The LEDs on the I/O module display the status of the external SCSI bus terminators and the power connection.

This property enables you to identify a specific drive. On an HS-series controller, only the Fault LED blinks when you send the Locate command. The Activity LED is illuminated when the drive is active. Depending on the host controller, this LED can blink either by itself or in unison with the Online LED when there is SCSI bus activity. The operation of the Online LED depends on the controller, because some controllers cannot manage this LED. If the controller can manage the LED: · · The LED is illuminated when 5. 1-V DC power is available and the drive is correctly installed. The LED is not illuminated when one of the following conditions is indicated: HP StorageWorks Modular Smart Array 30 User Guide 2-11 Installing the System in a Rack -- There is no controller on the bus. -- The drive is not correctly installed in the system. · The LED blinks either by itself or in unison with the Activity LED when there is SCSI bus activity. Depending on the host controller, the Fault LED blinks when the controller detects an error condition. If the host controller can control the illumination status of the drive LEDs, the display patterns for various conditions can be interpreted as shown in Tables 2-2 and 2-3. CAUTION: Because some controllers cannot control all the drive LEDs, you could misinterpret the display. Refer to the controller documentation before using this table to determine whether the controller is capable of controlling all the LEDs. 2-12 HP StorageWorks Modular Smart Array 30 User Guide Installing the System in a Rack Table 2-3: Interpreting the Drive Status LED Illumination Patterns Activity LED (1) On, off, or blinking On, off, or blinking Online LED (2) On or off Fault LED (3) Blinking Interpretation A predictive failure alert has been received for this drive. On Off The drive is online and is configured as part of an array. If the array is configured for fault tolerance and all other drives in the array are online, you may replace the drive. Blinking Off The drive is rebuilding or undergoing capacity expansion. Removing a drive could terminate the current operation and cause data loss. On Off Off The drive is being accessed, but (1) it is not configured as part of an array, (2) it is a replacement drive and rebuild has not yet started, or (3) it is spinning up during the POST sequence. Blinking Blinking Blinking Either (1) the drive is part of an array being selected by an array configuration utility or (2) Drive Identification has been selected in Insight Manager. Removing a drive could cause data loss in non-fault-tolerant configurations. Off Off On The drive has failed and been placed offline.
