1 Introduction
The NetServer Storage System/6 provides external mass storage for use with the current line of HP NetServers. The NetServer Storage System/6 is compatible with the Small Computer System Interface (SCSI-2) industry standard. Both Fast and Fast-Wide SCSI-2 are supported. The embedded SCSI controllers in NetServers, SCSI host bus adapters (HBA) or Disk Array Controllers (DAC) provide the SCSI interface between the host system and the storage system. DACs and HBAs are available from Hewlett-Packard (check with your dealer). The NetServers, HBAs and DACs include software that supports a variety of operating systems.
The chassis contains horizontal mass storage shelves called SCSI device shelves in the upper area of the chassis and a hot-swap subsystem with six hot-swap shelves in two cages in the lower area. The SCSI device shelves support SCSI devices, such as tape drives. The hot-swap shelves support SCA-2 hot-swap disk modules provided by HP.
The SCSI connectors on the rear panel connect the storage system to the host system. The SCSI bus terminates inside the storage system cabinet. A power supply and the internal cabling necessary for most configurations are included in the storage system.
The NetServer Storage System/6 can be configured to solve a variety of storage problems. The disk modules are available in a variety of capacities to meet your mass storage needs. Mass storage devices and external SCSI cables are not included with the storage system. They must be ordered separately from your HP dealer.

General Operating Instructions
1 Introduction
Please read the following instructions carefully. They contain information on how to avoid data loss and damage to the system due to improper handling.
Reset Switch
The front panel’s reset switch resets the power supply, performs a self test, and can be used to set the unit identification number.
Power Supply R eset
If the power supply shuts down, momentarily pressing the reset switch initiates a power supply reset. The reset sequence takes about 15 seconds. The display and power-on LED are off during the reset sequence.
Self-Test
When a self-test is performed, the results are displayed on the LED. To perform a self-test, complete the following procedure:
1. With the power switch off, hold the reset switch and turn the power on.
2. Release the reset switch. The seven-segment LED blinks “8.8.” five times, then displays the firmware revision number. The unit then performs a power supply reset, as described above.
Unit Identific ation Num ber
A unit identification number can be set for identification purposes. It has no impact on the operation of the storage system. To change the unit identification number, complete the following procedure:
English
1. Press and hold the reset switch for approximately five seconds, until the LED starts its count (at one-second intervals). The numbers 1 through 16 and the letters “HP” display in sequence (“HP” is the default unit identification number).
7
1 Introduction
2. Release the reset switch when the desired number displays. The unit identification number displayed is stored in the EEPROM. The unit identification number does not change even if the storage system is power­cycled (unless this procedure is repeated).
NOTE The power supply does not reset when the unit identification
Power Cycling
On an active network, switching the storage system power on or off while the host system is operating may affect server operation. Always make sure it is safe to cycle the power before doing so. Alert network users that the mass storage will be unavailable while the power is off.
For example, if you are using the HP DAC Write Cache, power cycling could result in data loss. When using the Write Cache, use the JetSet utility (provided with HP NetServers) to flush the cache before you cycle power. Wait until the disk drives are idle and the Write Cache (if used) has been flushed before switching off power. This avoids corrupting any data transfer that may be in progress between the host system and a disk.
The status lights on the front of each disk indicate activity. The lights flash when the host system is transferring data. If no lights are flashing, the bus is idle and it is safe to switch off the power.
number is changed.
Continuous Operation
The storage system power should remain on whenever the host system is operating. The disk drives are not harmed by continuous operation; avoid cycling power unnecessarily.
8
Temperature Control
Keeping the unit within the range of normal operating temperatures (see Appendix A, “Specifications”) is important to the long life and proper function of the storage system. If the storage system cabinet has been exposed to temperature extremes, allow two hours for it to stabilize to room temperature and humidity before switching on the power.
Blank filler panels that cover the SCSI device shelves and the disk module shelves are installed by the factory. These panels must remain installed for the product to comply with safety and regulatory requirements, and to provide proper cooling for the disk modules. If a SCSI device shelf filler panel is lost, you can order replacements (part number C3310-60017). If a hot-swap storage device shelf filler panel is lost, you can order replacements (part number 5063-5676).
CAUTION To avoid the hazard of electrical shock and to ensure the cooling
If “FF” (fan fault) is displayed on the LED panel, the cooling fan has failed. Shut down the system as quickly as possible. Continued operation of the storage system with a failed fan could result in loss of data or damage to the storage system and installed devices.
1 Introduction
English
system functions properly, the storage system should not be operated with the door open.
The LEDs on the disk drive modules indicate the status of the cage. If all the disk drive module LEDs in a cage are flashing yellow, it indicates a possible over temperature condition in that cage. If all the drives in a cage are flashing red, it indicates the temperature in that cage has exceeded the operational temperature range. Immediately begin shut-down procedures and refer to the “Troubleshooting” chapter in this manual.
Placement
Do not block the cooling vents. Do not place the storage system closer than 6 inches to a wall to ensure sufficient air flow and cooling.

1 Introduction
Hot-Swap Disk Module Care and Relocation
Handle disk modules carefully. Disk modules are more susceptible to shock, vibration and electro-static discharge when they are not in the cabinet. Also, do not touch the SCSI edge connector pins when a disk module is out of the cabinet. The oils on your skin could weaken the contact.
Once the storage system has been configured and installed, a disk module should not be moved from one hot-swap shelf to another shelf. Relocating a disk module changes the SCSI address of that disk. If the SCSI address is changed, the storage system is not able to read the information on that disk and data will be lost.
Each disk module shelf is numbered. It is recommended that you mark each module with its shelf number prior to installation. If a disk module fails, remove the failed module and place a new module in the same shelf. Placing a replacement module in a different shelf or relocating a disk module will result in the loss of data.
Spin Up
The storage system must be powered up and the drives on the storage system allowed to “spin up” to speed before the HP NetServer is powered on. The drive activity light is on while the drive spins up. The light is off when the drive has spun up and there is no read/write activity. If the HP NetServer is powered on before the storage system is powered on and the drives have spun up, the host will not recognize the storage system devices.
NOTE If the SCSI addresses of the hot-swap shelves are set to 1-3 or 9-11,
they are programmed to delay startup. Wait at least two minutes after the storage systems are powered up before powering up the host system if any SCSI address is set to 1-3 or 9-11.
Using an Uninter ruptible Power Su pply
It is recommended that you operate your storage system on an uninterruptible power supply (UPS). If you do, refer to the documentation included with the UPS for complete instructions on connecting your storage system. The recommended UPS budget for a fully loaded storage system is 600VA.

2 Cabling Storage Devices and Setting
SCSI A ddresses
This chapter describes the NetServer Storage System/6, switch settings and common cabling configurations. Once the addresses are set and cabling is configured, the hardware can be installed as described in the next chapter.
CAUTION Be careful when handling electronic components. Electronic
components can be easily damaged by static electricity. Leave these sensitive components in their anti-static bags until you are ready to install them. Handle accessories as little as possible. When you must handle an accessory, handle it only by the edges or the mounting bracket. Avoid touching any contacts on the accessory connector. Before touching any components inside your storage system, touch a metal part of the chassis. The use of a grounding strap is recommended.
How you configure the storage system depends on your system’s requirements and the type of SCSI channel available from the host system. For example, the HP NetServer LH array model has two embedded Fast SCSI-2 channels and includes a PCI DAC card, which provides two Fast-Wide SCSI-2 channels.
Each channel supports a range of SCSI addresses. The addresses in each Fast SCSI-2 channel range from 0-7. The addresses in each Fast-Wide SCSI-2 channel range from 0-15. In both Fast SCSI-2 and Fast-Wide SCSI-2 configurations, address 7 is used by the controller. Therefore, each Fast SCSI-2 channel supports up to seven SCSI devices on addresses 0-6. Each Fast-Wide SCSI-2 channel supports up to 15 SCSI devices on addresses 0-6 and 8-15.
English
Each SCSI device on the same channel must have a unique address. An address of 1 on Channel 0 is different from an address of 1 on Channel 1.
The SCSI device shelves support only Fast SCSI-2 devices (addresses 0-6). For devices installed in the SCSI device shelves, the address is set on the device per the manufacturer’s instructions. SCSI addresses for the hot-swap subsystem are set using the switches in the storage system.
11
2 Cabling Storage Devices and Setting SCSI Addresses
The basic procedure for configuring the storage system is as follows:
1. Determine the desired configuration.
2. Power down the storage system and detach all power cords and external cables.
3. Open the storage system door. The procedure is described in the “Opening the Door” section of this chapter.
4. Set the switches that determine the SCSI addresses for the hot-swap cages as described in the “Setting SCSI Addresses” section of this chapter.
5. Set the SCSI addresses for the devices on the SCSI device shelves as described by the manufacturer of the devices.
6. Install the SCSI devices in the SCSI device shelves as described in the “Installing Hardware Accessories” chapter.
7. Attach the cables to the devices as described in the “Cabling Configurations” section of this chapter.
8. Close the door.
9. Attach all power cords and external cables.
10. Power-up the storage system.
Opening the Door
If you are installing any hardware accessories, such as SCSI mass storage devices, you must open the door on the side of the storage system.
WARNING Always unplug all power cords and cables from the system before
opening the door.

Cabling Configurations
The storage system can be reconfigured by changing the internal cabling configuration or changing the switch settings on the cages. This section describes the external, the internal default, and some (but not all possible) internal cabling configurations and switch settings for both the hot-swap cages and the SCSI device shelves.
External Cabling
The storage system uses external, SCSI cables (not included) to communicate with the host system. Cables used with this product must be properly shielded to comply with regulatory requirements. The connection(s) at the back of the storage system are 68-pin, high-density connectors. Using the appropriate external SCSI cable, the storage system can be connected to the host system by using a variety of connectors (see Table 2-3 for the appropriate cable). The
16
2 Cabling Storage Devices and Setting SCSI Addresses
external cables connect from the host system to the rear panel of the storage system cabinet.
For instructions on connecting the external cables to the storage system, consult the host system user’s guide or in the case of a DAC card, the user’s guide for the DAC card.
At least one external SCSI cable is required to attach each storage system to the host system. All connections from the storage system to the host must be direct. Do not connect storage systems in series, or connect to other external SCSI devices.
Many of the cabling configurations need more than one external SCSI cable. If you need additional cables, they can be ordered from HP. The storage system is not shipped with external SCSI cables. Table 2-3 lists some of the external SCSI cables available from HP.
