alarm will turn off when the fault condition is cleared or the alarm can be disabled by issuing a

PowerAudibleAlarm or AudibleAlarm command via

CLI as described in Diagnostic Commands on page

41.Disabling the alarm for a specific error will not silence the alarm for other error conditions.

Specific situations and suggestions

For all problems, first check the pages of the ExpressNAV interface appropriate for the problem especially the Status and Storage Management or use the appropriate CLI commands

If a drive fails to respond

•Determine which drive has failed by observing the amber fault LED on the drive sled or connect to the CLI and type driveinfo for a list of all drives and their status.

•For specific information on a particular drive in CLI, type driveinfo [sled number] [drive number]. Record all errors.

•Determine if the drive is configured in JBOD or RAID Level 0.

•Follow the instructions in the appropriate chapters of this manual for removing, replacing and reconfiguring the drive (begin with Hot Swap Operating Instructions on page 71)

•You may copy drives by using Command Line interface commands. (Refer to Drive Configuration Commands on page 45).

If a power supply fails

•Verify the power cord is correctly plugged and there is power at the power receptacle.

•If there is power, the cord is secure and the blower and power supply LEDs are off, replace the blower unit (refer to Hot Swap Operating Instructions on page 71).

•If there is power, the cord is secure and the power supply LED is off, but the blower LED is on, replace the power supply (refer to Hot Swap Operating Instructions on page 71)

•Command Overlap: The array contains special software to take advantage of the Command Overlap feature offered in some high performance disk drives. Because all 24 disk drives in a Diamond Array may be seeking at the same time under Command Overlap, only

83

arrays with two operational power supplies and blower assemblies will support Command Overlap: the array will automatically disable the Command Overlap feature if a power supply fails and notify the system administrator through the audible alarm and CLI.

If you cannot read or write to the array

•You may have lost connection to the host via the Host Interface Card. The Host Interface Card LED on the back of the array should be lit green. The amber LED should go out and the green LED should light when the connection is complete.

•Also check the host bus adapter (HBA) in the host machine for proper functioning and drivers.

•Verify that the connector and both ends of the cable are completely seated.

•Try connecting directly to the host, bypassing any hubs or switches.

To determine if the problem exists with the HIC

•Swap the cable from one HIC to the other HIC.

•If the LED is now green, swap the cable back to the original HIC. If the LED is amber, the HIC is defective.

•Swap the defective HIC (refer to Hot Swap Operating Instructions on page 71)

If you can’t access the CLI via Ethernet

•Verify there are three or fewer concurrent sessions using Telnet or FTP. You may be the fourth session or someone in another session has entered a command which requires a Save Configuration command.

•Verify you are using a crossover cable for direct connection, or a network cable for a network connection.

•Verify the array is set to IPDHCP enabled if you expect an IP address will be assigned by the network and DHCP is an option available on the network.

•Verify the IP address is compatible with the host machine.

•Verify the system is functioning and accessible via in-band inquires such as Disk Management.

•Try setting your terminal emulator with a different baud rate, starting at 2400, then 9600, 19200, 38400, 57600, and 115200.
