International Business Machines Corporation Armonk, New York, 10504
The warranties provided by IBM in this Statement of Limited Warranty1apply only to Machines you originally purchase for your use, and not for resale, from IBM or your reseller. The term “Machine” means an IBM machine, its features, conversions, upgrades, elements, or accessories, or any combination of them.
Unless IBM specifies otherwise, the following warranties apply only in the country where you acquire the Machine. If you have any questions, contact IBM or your reseller.
Machine: IBM Fibre Channel RAID Storage Server and
Warranty Period: One Year*
* Contact your place of purchase for warranty service information.
Production Status
Each Machine is manufactured from new parts, or new and used parts. In some cases, the Machine may not be new and may have been previously installed. Regardless of the Machine’s production status, IBM’s warranty terms apply.
Expandable Storage Unit 2102 Model F10 and 2102 Model D00
The IBM Warranty for Machines
IBM warrants that each Machine 1) is free from defects in materials and workmanship and 2) conforms to IBM’s Official Published Specifications. The warranty period for a Machine is a specified, fixed period commencing on its Date of Installation. The date on your receipt is the Date of Installation, unless IBM or your reseller informs you otherwise.
During the warranty period IBM or your reseller, if authorized by IBM, will provide warranty service under the type of service designated for the Machine and will manage and install engineering changes that apply to the Machine.
For IBM or your reseller to provide warranty service for a feature, conversion, or upgrade, IBM or your reseller may require that the Machine on which it is installed be 1) for certain Machines, the designated, serial-numbered Machine and 2) at an engineering-change level compatible with the feature, conversion, or upgrade. Many of these transactions involve the removal of parts and their return to IBM. You represent that all removed parts are genuine and unaltered. A part that replaces a removed part will assume the warranty service status of the replaced part.
If a Machine does not function as warranted during the warranty period, IBM or your reseller will repair it or replace it with one that is at least functionally equivalent, without charge. The replacement may not be new, but will be in good working order.

If IBM or your reseller is unable to repair or replace the Machine, you may return it to your place of purchase and your money will be refunded.
If you transfer a Machine to another user, warranty service is available to that user for the remainder of the warranty period. You should give your proof of purchase and this Statement to that user. However, for Machines which have a lifetime warranty, this warranty is not transferable.
Warranty Service
To obtain warranty service for the Machine, you should contact your reseller or call IBM. In the United States, call IBM at 1-800-IBM-SERV (426-7378) In Canada, call IBM at 1-800-465-6666. You may be required to present proof of purchase.
IBM or your reseller will provide certain types of repair and exchange service, either at your location or at IBM’s or your reseller’s service center, to restore a Machine to good working order.
When a type of service involves the exchange of a Machine or part, the item IBM or your reseller replaces becomes its property and the replacement becomes yours. You represent that all removed items are genuine and unaltered. The replacement may not be new, but will be in good working order and at least functionally equivalent to the item replaced. The replacement assumes the warranty service status of the replaced item. Before IBM or your reseller exchanges a Machine or part, you agree to remove all features, parts, options, alterations, and attachments not under warranty service. You also agree to ensure that the Machine is free of any legal obligations or restrictions that prevent its exchange.
You agree to:
1. obtain authorization from the owner to have IBM or your reseller service a
2. where applicable, before service is provided:
IBM is responsible for loss of, or damage to, your Machine while it is 1) in IBM’s possession or 2) in transit in those cases where IBM is responsible for the transportation charges.
Extent of Warranty
IBM does not warrant uninterrupted or error-free operation of a Machine. The warranties may be voided by misuse, accident, modification, unsuitable
physical or operating environment, improper maintenance by you, removal or alteration of Machine or parts identification labels, or failure caused by a product for which IBM is not responsible.
THESE WARRANTIES REPLACE ALL OTHER WARRANTIES OR CONDITIONS, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OR CONDITIONS OF MERCHANTABILITY AND FITNESS FOR A

Power On/Off Subsystem Components
Note: Subsystem components must be powered up in the correct sequence to ensure proper operation.
Power Up Sequence:
1. rack (ensure that power for attached subsystem components is off)
2. hub
3. device drawers
4. controller module
5. host (wait until all drives have spun up to speed)
Power Off Sequence:

2. controller module
3. device drawers
4. hub
5. rack
Component Power On/Off Procedures:
rack Rack power is active when each Power
Distribution Unit (PDU) power cord is plugged in. A green light on the PDU indicates that power is active to that PDU. Each PDU should be powered on before continuing.
hub Hub power is active when the hub power cord is
plugged in.
Device Drawer Wait at least 30 seconds after powering off a
device drawer before turning power back on. Turn on both power switches on the back of the drawer. An LED on the back of the ESM board indicates that power is active. Refer to “Turn On the Power” on page 153 and “Turn Off the Power”
on page 154 for details.
Controller Module Turn on/off both power switches on the back of

...Then perform this action
1. Go to “Identifying Interface Problems” on page 87 and follow the procedure for the debugging of interface problems. If this fails to solve the problem, then go to Step 2.
2. Connect a service terminal to the top serial port on the back of the controller module and start RAID Manager for DOS (DRM). See “Chapter 16. RAID Manager for DOS” on page 205 for information on setting up and starting DRM.
3. Using DRM, run the Array Monitor utility to check the current status of array components and verify the communication paths within the array subsystem. Follow the procedure in “Verifying the Installation” on page 212.
v If the Array Monitor indicates a component failure within the array, then replace
the failed component.
v If the Array Monitor runs without indicating a failure (that is, it displays the
message ″Waiting for Next Polling Period″), then go to Step 4.
4. Using DRM, run the Array Configuration Editor (ACE) to verify the communications between the controllers and the devices and check the status of the devices.
a. If ACE indicates that the controller is not communicating over a specific drive
channel (that is, the Drive Window in ACE shows no devices on channel 6, but there is a SCSI cable connected to channel 6 on the back of the controller module), then replace the SCSI cable connected to that channel.
b. If ACE indicates that the controller is not communicating with a specific drive
or indicates a failure on a specific drive, then replace the defective drive.
c. If ACE indicates a problem with LUN 0 or LUN 0 is not optimal, then you must
fix the problem with LUN 0 in order to enable communication with the host. If the problem cannot be fixed by replacing hardware, you may need to delete and recreate LUN 0. If you do this, all data on LUN 0 will be lost. Make sure the customer is aware of your actions and call your next level of support for assistance. Note: One possible case of an off-line LUN 0 can occur when a drive drawer containing LUN 0 configuration information is added to an existing subsystem. In this case, the subsystem has conflicting information about the LUN 0 configuration and you must remove and rebuild the LUN.
d. If ACE does not indicate any failures or communications problems, then go to
Step 5.
5. Repeat steps 2 through 5 using the bottom serial port on the back of the controller module.
6. There is a problem with the Fibre Channel host adapter or in the fibre channel path between the host and the subsystem. Perform the following steps:
a. Recheck the fibre channel cables between the host and the controller and
replace if necessary.
b. If there is a hub in the fibre channel path, verify that there are no failures in
the hub. See
Guide, IBM 2103 Model H07
c. Verify that the host fibre channel adapter is configured properly. d. Verify that the host fibre channel adapter is at the correct firmware level. e. Verify that the host fibre channel adapter is working properly and replace if
necessary. If the subsystem is attached to a system running AIX, run diagnostics from the host on the fibre channel adapter to check for problems. For information on running diagnostics on the adapter refer to

Important: Diagnostics may take a long time (up to 40
minutes) if interface problems exist.
Action:
1. If you have not already done so, run the Advanced Diagnostics in System Verification mode from the diagnostics interface (type diag from the command prompt).
If the controller does not return to the On-line status, then the problem is at the connection or RAID controller. Go to Step 2 to check the connection. If the controller returns to the On-line status, then return to normal operation (see MAP 0410 in
Systems
2. Check both ends of the connections of external cables and hubs for bent pins, loose connections, or visible damage. If there is a problem with the connection, go to Step 3. If these components are OK, you probably have a defective RAID Controller. Go to Step 4.
3. Fix the connection problem (for example, reconnect or replace cable), then rerun the Advanced Diagnostics in System Verification mode.
If the controller does not return to the On-line status, then you probably have a defective RAID controller. Go to step 4 to replace the RAID controller. If the controller returns to the On-line status, then return to normal operation (see MAP 0410 in

4. Replace the controller using the procedure in “Replacing a Failed Controller” on page 93.
5. Run the Advanced Diagnostics in System Verification mode from the diagnostics interface.
If the controller does not return to the On-line status, then you may have a defective controller backpanel. Go to Step 6 to replace the backpanel. If the controller returns to the On-line status, then return to normal operation (see MAP 0410 in SA38-0509).
6. Replace the controller backpanel using the procedure in “Replacing a Failed Controller Backpanel” on page 98.
7. Run the Advanced Diagnostics in System Verification mode from the diagnostics interface.
If the controller does not return to the On-line status, then you may have a defective adapter. If the controller returns to the On-line status, then return to normal operation (see MAP 0410 in

Location Codes Displayed By Diagnostics
When the AIX diagnostics detect a failure in the 2102 Fibre Channel RAID subsystem, the failure information includes a location code used to physically identify the failing component within the subsystem. The following describes how to interpret the reported location codes:
v Translating location codes for a disk drive failure:
Disk drive failures will be reported in the following format:
653153: Drive failed by user via Mode Select. Refer to the 2102 Model F10 Service Guide for more information. 100% 17.357GB CH5 ID8 D0 Disk module
Location code CH5 ID8 D0 indicates that the failing disk drive is on channel 5, SCSI ID 8 and is assigned to dac0.
v Translating location codes for other subsystem component failures (other
than disk drives):
Subsystem component failures, other than disk drives, will be reported in the following format:
555203: Enclosure status reports a non-critical fan failure. Refer to the 2102 Model F10 Service Guide for more information. 100% E6 D0 Fan module
Location code E6 D0 means the fan is in the enclosure with EID=6 and assigned to dac0.

The step-by-step procedures in this chapter will guide you through the entire installation process. These procedures include:
© Copyright IBM Corp. 1999 35
v Preparing the site v Preparing the cabinet v Preparing the drive modules v Preparing the controller module v Completing the installation
You should perform these tasks in the order given, beginning with “Preparing the Site”.
Preparing the Site
This section lists the space, environmental, and power requirements for the 2102 subsystem. For information on interface cables and connections, refer to “Fibre Channel Host Cable Requirements” on page 42 and “LVD-SCSI Drive Cable Requirements” on page 42.
Floor Space
The floor area at the installation site must provide: v Enough stability to support the weight of the controller module, drive modules
and associated equipment. (Table 6 and Table 7 on page 37).
v Sufficient space to install and service the controller module, drive modules and
associated equipment. Allow a 36 inch wide service area in front and back of the subsystem components (see Table 8 on page 37 and Figure 1 on page 37 for controller module dimensions; Table 9 on page 37 and Figure 2 on page 38 for drive module dimensions).
Weight
The rack’s total weight depends on the number of components installed in the rack. Table 6 and Table 7 on page 37 respectively list the overall weight of the controller module and the drive module (unit and shipping), plus the weight for individual components. The maximum weight equals a controller module or a drive module fully populated with the heaviest FRUs. Empty weight equals a controller module or drive module with all FRUs removed.

Site Wiring and Power Considerations
The controller module is a nominal 90 v AC to 264 v AC, 50/60 Hz unit that meets standard voltage requirements for both domestic (USA) and international (outside USA) operation. It uses standard industrial wiring with a line-to-neutral or line-to-line power connection (Table 13 on page 40).
Consider the following when preparing the site and cabinet for installation:
Chapter 2. Installation And Removal Guide 39
v AC power source. The AC power source must provide the correct voltage,
current, and frequency specified on the manufacturer’s nameplate. Internal AC distribution boxes (such as the cabinet’s power units) must be able to handle the power requirements for this unit (Table 11 on page 39). You must have an independent AC power source for each power supply in the controller module in order to maintain redundancy.
v Earth ground. There must be an earth ground conductor on the AC power
source.
v Circuit overloading. Make sure the power circuits and associated circuit
breakers in both the cabinet and building provide sufficient power and overload protection. To prevent possible damage to the unit, isolate its power source from large switching loads (such as air conditioning motors).
v Power interruptions. The controller module will withstand the following applied
voltage interruptions: – Input transient: 50% of nominal voltage – Duration: one half cycle for the controller module; one full cycle for the drive
module
– Minimum frequency: once every 10 seconds
v Power failures — Once power is restored after a complete power failure, the
unit will automatically perform a power-up recovery sequence without operator intervention.

Power Cord Routing Notes
The controller and drive module each use two AC power cords (one for each power supply).
The rackmount cabinet may have one or two AC Power Distribution Units (PDUs). Each PDU has its own power cord. Ideally, the redundant power supplies on the controller and device modules will each be connected to a separate PDU to provide AC power source redundancy. However, if the rack contains only a single PDU, then all power supplies will have to be connected to a single AC power source.
Additionally, if there are not enough PDU outlets for every power supply of all rack components, then it will be necessary to use a Y power cable to connect two power supplies to the same PDU outlet.
The power cabling priority should be:
40 IBM 2102 Model F10 and Model D00 Service Guide
1. There is at least 1 PDU outlet available for each module (controller, drive or hub) in the rack. This is the minimum requirement.
2. If there is only a single PDU in the rack, but an outlet is available, then each controller module power supply should be connected to a different PDU outlet.
3. If there is only a single PDU in the rack and each controller module power supply is connected to a separate PDU outlet and there are still outlets available, then each device module power supply should be connected to a separate PDU outlet until no more outlets are available.
4. If there are 2 PDUs in the rack, then each controller module power supply should be connected to a different PDU.
5. If there are 2 PDUs in the rack and each controller module power supply is connected to a different PDU and there are still outlets available, then each device module power supply should be connected to a different PDU until there are no more outlets available.
Interface Connectors and Cables
The controller module supports the following interface protocols:
v Host interface – Fibre Channel (copper wire or fiber optic), one per controller v Drive interface – LVD-SCSI (low-voltage differential, small computer system
interface), six drive channels
v Diagnostic interface – Ethernet or RS-232 (serial), one each per controller
Connectors and Host IDs
The host ID switches and connectors for interface cables are on the (Figure 3), located on the back of the controller module.
connector plate
Figure 3. Interface Connections on Controller Module
Chapter 2. Installation And Removal Guide 41
Host and Drive ID Numbers
Each controller on a Fibre Channel loop must have a unique
Fibre Host ID number
The host ID numbers assigned to each controller are based on two elements: v Host ID numbers set through hardware switches on the controller module (see
Figure 3 on page 41). There are seven Host ID switches that allow you to set ID numbers 0 through 127 for each controller. The factory default settings are ID #5 for Controller A and ID #4 for controller B (see “Configuring the Controller Module” on page 54).
v Software algorithms that calculate the actual Fibre Channel address, based on
the controller module’s hardware settings and position on the loop or hub.
There are also
drive SCSI ID numbers
that identify each controller to the LVD-SCSI drives. Drive ID numbers are assigned to each controller at the factory and cannot be changed. However, SCSI drive IDs on drive modules can be changed manually. Refer to Step 5 on page 51 under ″Installing the Drive Module″ for details on setting the drive SCSI IDs.
Fibre Channel Host Cable Requirements
Table 14 lists the cable requirements for all Fibre Channel connections. For fiber optic connections, you must use multi-mode, 50 micrometer fiber optic cable and a Media Interface Adapter (MIA) shown in Figure 4.

LVD-SCSI Drive Cable Requirements
To connect the controller module to a drive module, you must use 68-pin, VHDCI (very high density cable interface) LVD, Ultra SCSI-2 cables. The maximum length for any SCSI cable is 25 m (82 ft.). Refer to “SCSI Cables” on page 194 for SCSI cable information. The controller module has six drive SCSI connectors that support both 8-bit and16-bit interface protocol. Each connector represents a single drive channel that supports up to 10 drives per channel for a total of 60 drives. Refer to “LVD-SCSI Drive Cable Routing Examples” on page 59 for examples of connecting the controller module to one or more LVD-SCSI drive modules. Table 15 on page 43 lists the SCSI cable that you can use on this drive module.

Installing the Support Rails About Support Rails
To install the controller module or drive modules in a rackmount cabinet, you need the appropriate rackmount support rail kit.
Where you place the support rails in the cabinet depends on where you intend to position the controller or device modules in the cabinet. In a standard configuration, the controller module is installed at the top of the rack and device modules are installed beginning at the bottom of the rack and moving upwards. If you are using a different type of mounting system, refer to the documentation shipped with your cabinet hardware.
Note: If your cabinet already has a set of support rails installed at the position
where you are installing the controller or drive modules, you may skip to the next task.
Instructions
Use this procedure only if you need to install mounting hardware in a cabinet before installing a controller or drive module. These instructions assume that you are following the cabinet preparations task list in “Cabinet Preparation Task List” on page 43. Make sure that you have a minimum of two feet around the outside of the cabinet in order to install the support rails and complete the remaining installation procedures.

v Make sure that the fans are in the correct orientation before you
attempt to install them (see Figure 12 on page 50).
5. Set the Drive Module Interface Options.
Chapter 2. Installation And Removal Guide 51
There is a Tray ID switch and a set of Option switches on the back of the Drive Module that are used to select interface options, and to determine whether these drives are configured as two 5-drive buses or one 10-drive bus (see Figure 14 on page 53). These switches should be set as follows:
v Tray ID:
This switch is used to identify the drive module based on its location in the rack. The rack will support up to six drive modules and the tray ID must be unique for each. Drive Modules should be installed beginning at the bottom of the rack, moving upward with each succeeding Drive Module installation.
Set the Tray ID of the first (bottom most) Drive Module to ″1″, set the second Drive Module Tray ID to ″2″, and so on, proceeding to the sixth Drive Module (Tray ID=″6″), installed immediately below the Controller Module. This is a fully populated rack.
v Option Switches:
These switches are used to set the interface options and set the SCSI IDs of the drives in the Drive Module. Unless instructed otherwise, you should only have to change Switch 1, the Bridge Disable bit. All other option switches should be in the ″OFF″ position (see “Factory Settings” on page 191 for more detail about Option Switches).
When the Bridge Disable switch (Switch 1) is in the ″ON″ position, the Drive Module acts as two independent 5–drive buses with one SCSI connection to each bus. When this switch is ″OFF″, the Drive Module acts as one 10–drive bus with two SCSI connections (see “Drive Numbering” on page 144).
The setting of this switch is determined by the number of drive modules installed in the rack:
a. 1, 2 or 3 drive modules installed: The Bridge Disable bit (switch 1)
should be in the ″ON″ position for all drive module and each module should have two SCSI connections to the controller module.
b. 4 drive modules installed: The Bridge Disable bit (switch 1) should be in
the ″ON″ position for drive modules 2 and 3 (the second and third drive modules from the bottom of the rack), and ″OFF″ for drive modules 1 and
4. Drive modules 2 and 3 will each have two SCSI connections to the controller module, and drive modules 1 and 4 will each have a single SCSI connection to the controller module.
c. 5 drive modules installed: The Bridge Disable bit (switch 1) should be in
the ″ON″ position for drive module 3 (the third drive modules from the bottom of the rack), and ″OFF″ for drive modules 1, 2, 4 and 5. Drive module 3 will have two SCSI connections to the controller module, and all the rest will have a single SCSI connection to the controller module.
d. 6 drive modules installed: The Bridge Disable bit (switch 1) should be in
the ″OFF″ position for all drive module and each module will have single SCSI connections to the controller module.
See “LVD-SCSI Drive Cable Routing Examples” on page 59 for examples.
52 IBM 2102 Model F10 and Model D00 Service Guide
Figure 14. Tray ID and Option Switches
6. Connect the Cables There are two SCSI interface connectors on the ESM board (Figure 15 on
page 54) for attaching the SCSI cables from the controllers to the Drive Module SCSI buses. Depending on the setting of the Bridge Disable switch (Option Switch 1), you will have to connect either one or two SCSI cables between the controller and drive modules:
v If the Bridge Disable switch is in ″ON″ position: Connect two cables, one
to each connector on the ESM board.
v If the Bridge Disable switch is in ″OFF″ position: Connect one SCSI cable
to the Bus 1 one connector (left connector when viewed from the back) on the ESM board.
Attach the SCSI interface cables from the controller module to the SCSI connectors on the ESM board.
7. Route and secure the SCSI interface cables. Arrange the interface cables so that they clear the vents on the back of the
module. Secure the cables with tie-wraps.
8. Connect the power cords (Figure 15 on page 54). Read “Power Cord Routing Notes” on page 40. Make sure both power switches
are turned off and connect both power cords to the drive module.

2. Verify that the Media Interface adapters are securely attached to the fibre
channel connectors (J3 and J4) on the back of the controller module (Figure 11
on page 49
Chapter 2. Installation And Removal Guide 55
on page 49). Attention: Bending or damaging Fibre Channel cables could result in degraded performance or data loss. Do not pinch the cables with tie wraps. Do not make sharp bends when routing the cables. Do not step on the cables or locate them in aisles or walkways.
3. Attach the host Fibre Channel cables (Figure 11 on page 49). Attach the Fibre Channel cable from host adapter 1 to connector J3 (Fiber Host
BD 1) on the back of the controller module. Attach the FC cable from host adapter 2 to connector J4 (Fiber Host BD 2).

the controller module’s status. If any Fault LEDs turn on and remain on, refer to the appropriate page listed in Table 16 on page 76 and Table 17 on page 78.
Go to “Check the Overall Hardware Status” on page 156 and follow the instructions for checking the drive modules’ status. If any fault LEDs come on and remain on, refer to the appropriate Service Page listed in Table 33 on page 157 and Table 34 on page 158.
7. Replace the controller module front cover (Figure 6 on page 46).
8. Go to “Verifying the Installation”.
End of Procedure
Verifying the Installation
Tools and Equipment
You will need access to the Fibre Channel Storage Manager host software.
Instructions
Use this procedure as a guideline for verifying the subsystem configuration.
1. Read “Configuration Notes” on page 56.
2. Verify the installation using the Fibre Channel Storage Manager host software. Some default software parameters (such as RAID level, drive groups, and
caching) are set at the factory before shipment. If Fibre Channel Storage Manager software is already installed on the host, use it to check the current software configuration for both the controllers and drives and to verify that both controller boards and all drives can be seen by the host. You may also need to change the mode of the controllers from active/passive to active/active. Refer to the appropriate software documentation for instructions on using the software.
v If the subsystem is attached to a Windows NT, SUN, or HP-UX host, then
use the Configuration application to verify that both controller boards and all drives can be seen by the host. Refer to
StorWatch Fibre Channel RAID Specialist, User’s Guide
using the software.
v If the subsystem is attached to an AIX host system, use the Disk Array
Manager to verify that both controller boards and all drives can be seen by the host. Refer to
Fibre Channel Storage Manager, Installation and User’s
Guide for the AIX Operating System
Fibre Channel Storage Manager and
for instructions on
for instructions on using the software.

may be identified by names that differ from those used in this book. Keep this in mind when using the software.
End of Procedure
Removal
If you are removing the subsystem from service, you must be sure to erase any user data on the array. Have the customer use the Storage management software to format all existing LUNs and then delete the configuration. If the host connection is not available or already disconnected, you can use DOS RAID Manager (DRM) to perform these operations. Make sure the customer understands that all data will be lost and unrecoverable. If drive drawers are being moved to another subsystem, you must remove the configuration information written on the drives to avoid problems. Make sure that all the drives in the drawer being used are ″unassigned″ (not part of any drive groups or LUNs) before moving.
Important: If the ″Reset Configuration″ option is used to delete the configuration
information on the drives, be aware that this function results in the creation of a default LUN 0. You must delete this LUN after the reset configuration function completes.
