HP Smart Array 6400 Series Controller Support Guide

Board Components and Features

The Smart Array 6402 Series Controller has two Ultra320 SCSI channels and 192 MB of cache,

128 MB in the cache module and 64 MB on the board.

The Smart Array 6404 Series Controller has two controllers. Each controller has two Ultra320

SCSI channels and 256MB of cache, 128MB in the cache module and 64MB on each controller.

CAUTION: The Smart Array Controllers have two (6402) or four (6404) channels. There are two channels on the 6402 base controller, each having one internal and one external connector. One connector can be used per channel at any given time. If both the internal and external connectors on the same channel are connected to the Itanium platform and boot is attempted, the following message displays:

1783 - Drive Array Controller Failure!

[Controller self-test failure (failure code = 0093]

Until this problem is fixed, the controller will not be available upon boot. If the system is booted, the Smart Array locks up.

NOTE: Booting from channels B1 and B2 of the Smart Array 6404 Series Controller is not supported.

LED Name and Interpretation

Diagnostic/Cache Status LED. LED flickers during cache activity. LED is constantly on indicates a cache error.

Drive Failure LED. A physical drive connected to the controller has failed.

SCSI Bus Active LED. At least one of the SCSI busses on the controller is active.

XOR Active LED. The controller is calculating parity data.

Command Outstanding LED. The controller is working on a command.

Heartbeat LED. This LED flashes every two seconds unless the controller is malfunctioning.

High Activity LED. This LED illuminates when the controller is busy.

Idle Task LED. Under normal circumstances, this LED flashes once per second. When the controller is busy, the LED is constantly illuminated.

Status Charging LED. The controller battery is being charged.

NOTE: During server power on, each runtime LED illuminates randomly until POST completes.

Cache Module LEDs

The cache module has two runtime LEDs that indicate various activities and error conditions.

Interpretation

The cache batteries are charging.

The cache micro controller is waiting for the host controller to communicate.

One of these conditions is present:

• There is a short circuit across the battery terminals or within the battery pack.

• The host controller is updating the cache micro controller firmware.

Fast Blink There is an open circuit across the battery terminals or within the battery pack.

Slow Blink (once every 16 seconds)

The cache contains data that has not yet been written to the drives. This display pattern may occur after the system is powered down; restore system power within four days to prevent data loss.

PCI System Interface

The Smart Array Controllers interface with the system through a high-performance 64-bit PCI-X

(or PCI) bus that does the following:

• Runs at speeds up to 133 MHz

• Provides a high-speed data path (up to 1.0 GB/s) between the system board and the controller

• Includes two parity protection signals

The Smart Array Controllers are PCI-X Bus Master devices that conform to Rev. 1.0 of the PCI-X

Local Bus Specification. A bus master device takes control of the PCI bus during high-speed transfers, freeing the system processor to handle application processing or other tasks.

For maximum performance, HP recommends that you use only 133 MHz devices on any given

133 MHz PCI-X bus. Combining 133 MHz and 66 MHz devices on a PCI-X bus decreases the overall bandwidth to 66 MHz speeds.

SCSI Support

The Smart Array Controllers support Low Voltage Differential (LVD) signaling only. They support disk drives that conform to Ultra320, Ultra160, and Ultra2 standards. If Ultra320, Ultra160,
