Table 2. Symptom-to-FRU index for front view LEDs (continued) Symbol Problem Indicator Action Amber Storage Subsystem Fault LED is lit solidly. If the fault LED is lit continuously (not flashing), there is a problem with the storage subsystem. Use the ServeRAID Manager program to diagnose and repair the problem. For more information, see the DS300 and DS400 Problem Determination Guide. One of more of the following conditions might exist: v Power supply fault v Fan fault v Overtemperature fault v RAID controller module fault v Battery fault v Cache DIMM fault v XScale DIMM fault v Disk drive fault v Turned ON through SES control page 1. Check the LEDs for all components on enclosure (disk drives, power supplies, controllers) and follow the solution instructions provided for the respective illuminated LED. 2. If no other fault LED is on, replace the controller: v DS300 1-RS (p/n 13N1894) v DS300 1-RL (p/n 13N1895) 3. If replacing the controller does not resolve the issue, replace the chassis/backplane assembly (p/n 13N1786). Amber Storage Subsystem Fault LED is lit flashing. When this LED is lit flashing, it indicates that an illegal hardware configuration is detected. Verify that the RAID controller and power supply are both installed in the slot A side. Note: This should only occur with the DS300 type 1701 (model 1RL. No label Green Hard disk drive activity LED is off. Start your application and verify that the activity No drive activity is being detected. LED flashes as the drive is accessed. No label Amber Hard Disk Drive Status LED is lit solidly. Each hard disk drive has a status LED. When this LED is lit solidly, it indicates that the drive has failed. Note: When this LED is flashing slowly (one flash per second), it indicates that the drive is being rebuilt. When the LED is flashing rapidly (three flashes per second), it indicates that the RAID controller is identifying the drive. For a single drive failure, replace the failed drive. For a multiple drive failure, attempt to determine the order in which the drives failed and then follow the appropriate recovery process for their RAID level. For additional information on troubleshooting drive-side issues, refer to the Drive Side PD Map in the DS300 and DS400 Problem Determination Guide. Table 3.
