I/O modules

TwoI/Omodulesprovideaninterfacebetweenthedisksandthehostsystem. TheI/Omodulesareused to route data to and from the disks in a dual-loop configuration to eliminate a single point of failure.

Each disk drive is connected to both I/O module A and I/O module B (Figure 4-3). Each I/O module is connected to an independent, external FC loop. I/O module A connects to loop A, and I/O module B connects to

CAUTION:

Keep the loops completely separate to ensure that the failure of a single component (I/O module, transceiver, or cable) does not stop data transmissions to active drives.

The operation and function of both I/O modules are identical. Each I/O module has two ports that can transmit and receive data for bidirectional operation. Port use and connections are configuration dependent (see "Cables and cabling" on page 24). Each port is identified with a transceiver element number,anditsstatusisdisplayedonanLED(Figure 5). Port 1 is the bottom loop port, and port 2isthetoploopport.

• Port 2 LED—On indicates that a signal was detected at the top transceiver.

o. 2 Phillips screwdriver.

WARNING!

A DS2500 with all components installed weighs more than 29.5 kg (65 lb.) and requires a minimum of two people to move. To safely and easily install the DS2500, using antistatic protection remove the drive blanks, power supply/blower assemblies, EMU, and I/O modules. This reduces the weight of the DS2500 to approximately 11.0 kg (24 lb). Even though a single person can lift this weight, the DS2500 is difficult to install because of its physical size. Therefore, HP recommends that a minimum of two peop

Reducing the enclosure weight

Before you install a DS2500, reduce its weight by removing the drive blanks, power supply/blower assemblies, EMU, and I/O modules. The removal procedures in this section do not apply to an operating enclosure, as they assume that there are no cables attached to the components, and no power is co

WARNING!

A DS2500 with all components installed weighs more than 29.5 kg (65 lb) and requires a minimum of two people to move. To safely and easily install the DS2500, remove the components as described in this section. This reduces the DS2500 weight to approximately 11.0 kg (24 lb).

WARNING!

A DS2500 without components installed weighs approximately 11.0 kg (24 lb). Even though a single person can lift this weight, the DS2500 is difficult to install because of its physical size. Therefore, HP recommends that a minimum of two people install an empty DS2500 in a rack.

To install a DS2500:

1. From the front of the rack, slide the DS2500 onto the rails.

2. Secure the DS2500 to the front of the rack by tightening the four thumbscrews (Figure 19).

of their specification, and normal operation of at least one component is impossible. HP recommends prompt corrective action to prevent system degradation.

• Noncritical—Occurs when one or more enclosure components have failed or are operating

outside of their specifications, but normal operation of the enclosure is possible. Additional errors, however, could affect the ability of the devices to operate correctly.

• Information—Advises you that a condition exists that could become an error and require

corrective action. In effect, an information condition provides an early warning, which enables you to prepare to implement corrective action before a component fails.

Error condition reports

NOTE:

An error always generates a condition report. However, condition reports may also be generated forcircumstancesotherthanerrors.

The EMU stores each condition report in an error queue for at least 15 seconds after the error is reported. This ensures that all errors are displayed in the event of multiple or recurring errors. The complete report is stored in the error queue. When you correct the error, the condition report is removed from the queue.

You can the use the EMU push buttons to display the condition report in the alphanumeric display.

IMPORTANT:

Always record the 6-digit error code, and call your HP service representative for a plan of action.

See "Error condition report (Er)" on page 42 for information about viewing the error condition reports. To decode the error condition report, see Appendix C.

Correcting the error removes the condition report from the error queue. An information error doesn't require repair, and is removed from the queue after a fixed period of time.

Status indicators

LEDs indicating DS2500 status are located on the front and rear of each enclosure.

Troubleshooting

Enclosure status icons are located on the front, lower right of the enclosure. These same icons can be seen from the rear of the enclosure on the top of the EMU.

Catastrophic errors

The design of the DS2500 allows it to continue operating in the presence of faulty hardware. However, a critically-high temperature in the enclosure can cause hardware failure and compromise data integrity. To prevent catastrophic data loss and further damage to components, the following conditions cause the DS2500 to shut down:

• A power supply removed from the enclosure

• No operational blowers

• An unacceptable temperature level in the enclosure

If any of these conditions exists, the EMU starts a timer to shut down the enclosure in 7 minutes. If the condition is corrected before the 7 minute countdown is completed, the EMU aborts the shutdown and normal operation resumes.

Best practices for replacing hardware components

The following information will help you replace the hardware components on your DS2500 successfully. Follow these ti

CAUTION:

Removing a component significantly changes the air flow within the enclosure. All components must be installed for the enclosure to cool properly. If a component fails, leave it installed until a replacement is available.

Components can be damaged by electrostatic discharge (ESD). Use proper antistatic protection as follows:

• Always transport and store CRUs in an ESD protective enclosure.

• Do not remove the CRU from the ESD protective enclosure until you are ready to install it.

• Always use ESD precautions, such as a wrist strap, heel straps on conductive flooring, and an

ESD protective smock when handling ESD sensitive equipment.

• Avoid touching the CRU connector pins, leads, or circuitry.

• Do not place ESD generating material such as paper or non-antistatic (pink) plastic in an ESD

protective enclosure with ESD sensitive equipment.

• Wait until periods of low storage system activity to replace a component.

When replacing components at the rear of the rack, cabling may obstruct access to the component. Carefully move any cables out of the way to avoid loosening any connections. In particular, avoid cable damage that may be caused by:

ps any time you replace a component.

• Kinking or bending tighter than a 1.375-inch bend radius.

• Placing removed cables on the floor or other surfaces, where they may be walked on or

otherwise compressed.

• Disconnecting cables without installing a dust cap. If a cable is uncapped, its performance may

be impaired by contact with dust, metal or other surfaces.

CAUTION:

Fiber optic cables do not transmit data consistently when compromised by dust and debris. To protect the connectors, always install the dust covers whenever a transceiver or a fiber cable is disconnected. Whenconnectingatransceiverorfibercable,remove,

Confer with HP technical support to verify that the hardware component has failed and that you are authorized to replace it yourself.

le hardware failures can complicate component replacement. Check the System Event Analyzer to

Multip detect any additional hardware problems.

Procuring the spare part

Parts have a nine-character spare component number on their label (Figure 29-1). The first six characters (123479) identify the component; the last three characters (002 in this example) define the revision level. The replacement component revision level must be the same as, or greater than, the number on the component being replaced. The higher the revision level, the later the revision.

Replacing a disk drive

Before you begin

Always use proper antistatic protection as described in the documentation that shipped with your system. Do not remove more than one disk drive or drive blank from an operating DS2500. Doing so impacts

air flow of the enclosure, and may cause data loss. HP recommends installing a disk of equal or greater capacity, or a drive blank, as soon as possible. Prevent possible data loss by verifying that the disk to be removed is in a failed state.

IMPORTANT:

When the system boots, HP-UX retrieves the loop ID and WWN of each disk and stores the information for disk authentication. When you replace a disk drive, the authentication fails because the WWN has changed. You must use fcmsutil to instruct the FC driver to ignore the authentication.

Federal Communications Commission (FCC) notice

Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established Radio Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many electronic devices, including computers, generate RF energy incidental to their intended function and are, therefore, covered by these rules. These rules place computers and related peripheral devices into two classes, A and B, depending upon their intended installation. Class A devices are those that may reasonably be expected to be installed in a business or commercial environment. Class B devices are those that may reasonably be expected to be installed in a residential environment (for example, personal computers). The FCC requires devices in both classes to bear a label indicating the interference potential of the device as well as additional operating instructions for the user.

The rating label on the device shows the classification (A or B) of the equipment. Class B devices have an FCC logo or FCC ID on the label.

C EMU-generated error condition reports

Error condition report format

When the EMU alphanumeric display is Er, three sub-levels of information provide details about the error condition: the element or component type, the specific component, and the error code. You can use this information to determine the probable cause of the problem.

• The first sub-level displays the element type (et), which identifies the type of component affected.

See Table 20 to decipher the element type code.

• The second sub-level displays the element number (en), which identifies the exact component

affected.

• The third sub-level display provides an error code (ec), which defines a specific problem.

NOTE:

The conventions used to differentiate between the bytes of the condition report are:

• Element type—Period after each character (0.1.)

• Element number—Period after the second character (01.)

• Error code—No periods (01)

Table 20 lists the element type codes assigned to the DS2500 components.

Disk drive error conditions

The format of a disk drive error condition report is 0.1.en.ec,where:

• 0.1. identifies a disk problem.

• en. identifies the affected disk drive bay number.

A direct correlation exists between the disk drive element number and the bay number. The bays are numbered sequentially 1 through 14 from left to right.

• ec is the error code.
