viii 2104 Service Guide
About This Book This book provides service information for any person who is required to service Expandable Storage Plus: 2104 Models DU3 and TU3 disk subsystems. That person could be a technically-qualified employee of the owner of the subsystem, or a service representative. This information is organized as follows: v Chapter 1 briefly introduces the 2104, and gives useful reference information. v Chapter 2 gives problem determination procedures. v Chapter 3 gives removal and replacement procedures.
Expandable Storage Plus: 2104 Model TU3 Installation Guide, For other publications, see “Related Publications” in Appendix A. Additional Information for RISC Systems.
Electrostatic Discharge When you handle field-replaceable units (FRUs) and other computer parts, take these precautions to avoid static damage: v Limit your movement. Movement can cause static electricity to build up around you. v Always touch computer parts carefully. Hold adapters and memory-modules by their edges. Never touch any exposed circuits. v Prevent people who are not correctly grounded from touching computer parts.
Safety Note Ensure that you read “Safety Notices” on page vii before you do any of the actions that are described in this book.
Chapter 1. Reference Information Are You Using the Correct Book? Do not use this book if you are servicing a 2104 Model DL1 or TL1. For the correct book, see Related Publications in Appendix A. Additional Information for RISC Systems. The Expandable Storage Plus: 2104 Models DU3 and TU3 subsystems (see Figure 1) can be attached to any RS/6000™ or IBM ™ ^™ pSeries computer that provides support for Small Computer System Interface (SCSI).
The 2104 Models DU3 and TU3 can contain up to 14 SCSI disk drive modules. These modules can be a mixture of various types, which vary in size (see “Chapter 4. Parts Catalog” on page 123). The 2104 can be disconnected from its related SCSI attachments (for example, SCSI adapters) while the using system is running. Also, most of the field-replaceable units (FRUs) of the 2104 can be removed and replaced while the 2104 and the using system are running.
SCSI Interface Cards The SCSI interface card of the 2104: v Provides SCSI Enclosure Services (SES). v Reads the VPD from the backplanes and the fan-and-power-supply assemblies. v Controls the Subsystem Check light and the disk drive module Check lights. v Controls the speed of the fan of the fan-and-power-supply assemblies or fan-and-power-supply assembly and fan assembly. v Monitors the ‘Emergency Power Off Warning (EPOW)’ signal from the power-supply assembly or assemblies.
−48 Volt Power Supply (Model DU3 Only) The −48 Volt Power Supply feature provides power supply assemblies that allow a 2104 Model DU3 to be connected to −48 volt power sources. The 2104 must be connected to two separate power sources to ensure that operations are not interrupted if one power source fails. The −48 Volt power distribution panel (PDP) in the rack provides the power sources and the power cables.
Lights and Switches The lights and switches of the 2104 consist of: v Subsystem lights v SCSI interface card lights v Fan-and-power-supply assembly lights and switch v Fan assembly light v Switch card assembly switches v Disk drive module lights Figure 2 shows the lights and switches of the 2104 Model DU3; Figure 3 shows the lights and switches of the 2104 Model TU3. Figure 2. Lights and Switches of the 2104 Model DU3 Chapter 1.
Figure 3.
Subsystem Lights To identify the lights that are described here, see Figures 2 and 3. The Subsystem Power light and Subsystem Check light are located on the backplane assembly. The lights are made visible by light pipes that pass through the bezel at the front of the 2104. Subsystem Power light 1 : This green light is on continuously when dc voltage is present in the 2104. Subsystem Check light 2 : This amber light comes on continuously if a failure occurs in the 2104.
Fan-and-Power-Supply Assembly Lights and Switch To identify the lights and switch that are described here, see Figures 2 and 3. DC On/Standby switch 10 : This switch switches off the dc electrical power to the disk drive modules and other components of the 2104. The switch must be set to On for the power supply and the fan unit to start.
Switch Card Assembly Switches The switch card assembly is item 9 in Figures 2 and 3. To identify the switch card assembly switches, refer to Figure 4. Figure 4. Switch Card Assembly Switches Notes: 1. In this section, “default logical setting” means the setting that the enclosure uses if the switch card assembly is not present when a power-on or reset operation occurs. 2. Switch 10 is not used, and must always be set to Off. Chapter 1.
External Switches Power Control switch 1 : When this switch is set to Off, the SCSI interface card can enable the 2104 power supplies if both the following conditions exist: v The 2104 is connected to mainline power and a DC On/Standby (on a fan-and-power-supply assembly) is set to On. v The ‘terminator power (TERMPWR)’ signal is active in an external SCSI connection. Under these conditions, the SCSI interface card provides a remote power on control function.
time before motor startup is specified for each disk drive module. After power is switched on, the delay time is usually SCSI ID x 12 seconds. For example, the delay for a disk drive module whose SCSI ID is 2 is 2x12 seconds (24 seconds). If the switch card assembly is not present when the 2104 is first switched on, or when the 2104 receives a ‘Reset’ signal, the default logical setting for this switch is Off. Enclosure ID switch 6 : This 10-position rotary switch sets the ID of the 2104.
v When the switch is set for the 2104 Model TU3, the two-color LEDs that are related to the 2104 Power light and to the 2104 Check light are set so that the upper LED becomes the green Power light, and the lower LED becomes the amber Check light. If the switch card assembly is not present when the 2104 is first switched on, or when the 2104 receives a ‘Reset’ signal, the default logical setting for this switch is Off (that is, for Model DU3).
Disk Drive Module Lights Figure 5. Disk Drive Module Lights The disk drive module light (LEDs) are located on the backplane of the 2104. They are made visible by light pipes that pass through the disk drive module. 1 Activity light: When on, this green light shows that a SCSI command is in progress. 2 Check light: This amber light shows the following conditions: Status of Light Off Permanently on Meaning Normal operating condition.
Fast flash (0.25 seconds on, 0.25 seconds off) 14 2104 Service Guide The disk drive module is a member of a RAID array, and is being rebuilt. (This action is a SAF-TE function.

v The front of racks should be positioned on floor-tile seams, with a full line of perforated tiles immediately in front of the racks. v Where racks are in rows front-to-front or back-to-back, there should be a gap of at least 1220 mm (48 in) separating the rows. v To ensure correct air flow within each rack, the rack filler plates must be installed in unused positions. Also, all the gaps in the front of the racks must be sealed, including the gaps between the 2104s. 2.
SCSI Addresses Each disk drive module is identified to the using system by a SCSI address. This address is related to the slot in which the disk drive module is installed. Although the SCSI address switch (see “Switch Card Assembly Switches” on page 9) allows the addresses of the slots to be reversed, do not use reversed settings; they are not supported on 2104 Models DU3 and TU3. Table 1 shows the SCSI addresses of the slots.
SCSI Bus Configurations and Addresses The SCSI bus bridge card assigns the disk drive modules to a SCSI bus as determined by the setting of the SCSI Bus Split switch that is on the switch card assembly. Three SCSI bus modes are available: v Single bus, one SCSI attachment (for example, a SCSI adapter in the using system): SCSI address 7 is assigned to the SCSI attachment. The 2104 can have 14 disk drive modules (SCSI addresses 0 through 6, and 8 through 14).

Vital Product Data (VPD) You can display the vital product data (VPD) for the 2104 by using the service aids. This section shows the types of information that are contained in the VPD.
2104 Service Aids Service aids are available for the 2104. For descriptions of those service aids, see “System Service Aids” in “Appendix A. Additional Information for RISC Systems”. 2104 Enclosure Services If the using system and the 2104 are both operating, you can use the ANSI SCSI Enclosure Service (SES) to determine the status of the 2104. Use the Receive Diagnostic Results command, and go to the enclosure status page (page 02).
Service Inspection Guide This inspection guide helps you to identify possible unsafe conditions on 2104s. Each 2104 has the necessary safety items installed to protect users and service personnel from injury. This guide addresses only those items. You should use your good judgment, however, to identify possible safety hazards that are not covered by this guide.
Checking the Grounding of the 2104 Go to the appropriate subsection for the 2104 that you are servicing. Grounding Check (2104 Model DU3) 1. Refer to Figure 16. Figure 16. Power Cables and SCSI Connectors (2104 Model DU3) 2. Ensure that all power is removed from the rack (see the Installation and Service Guide, or equivalent, for the rack or using system). 3. Ensure that the power cables 1 are plugged into each fan-and-power-supply assembly.
5. Follow your local procedures and check the grounding of the 2104. Any test equipment must be connected to the frame of the 2104 3 . v If the grounding is correct (see step 3a on page 31), go no further with these instructions. v If the grounding is not correct, unplug the power cables from the fan-and-power-supply assemblies in the 2104. If you are servicing a 220-volt 2104, go to step 6. If you are servicing a −48 volt 2104, go to step 9. 6. Refer to Figure 17. Figure 17.
If each fan-and-power-supply assembly has continuity, you might have a problem with the power cable or with the grounding of the using system. If you are servicing a 220-volt 2104, go to step 13. If you are servicing a −48 volt 2104, see the rack, or using-system, Installation and Service Guide, or equivalent, to isolate the fault, then do the complete grounding check again. 13. Check the power cable for continuity.
Grounding Check (2104 Model TU3) 1. Refer to Figure 19. Figure 19. Power Cables and SCSI Connectors (2104 Model TU3) 2. Ensure that a power cable is plugged into each power socket 1 . 3. Ensure that the other ends of the power cables are not plugged into electrical power outlets. Unplug the cables if necessary. 4. Attention: Some electrical circuits could be damaged if the external SCSI cables are present at the 2104 while the grounding check is being done.
9. If either power cable is failing, exchange it for a new one, then go to step 10 . 10. Refer to Figure 20. Figure 20. Ground Pin (2104 Model TU3) 11. Check for continuity between the frame of the 2104 and the ground pin 1 of the power connector on each fan-and-power-supply assembly. 12. If either fan-and-power-supply assembly does not have continuity, exchange that assembly for a new one (see “Fan-and-Power-Supply Assemblies” on page 89), then do the complete grounding check again.
Chapter 2. Problem Determination Procedures Are You Using the Correct Book? Do not use this book if you are servicing a 2104 Model DL1 or TL1. For the correct book, see Related Publications in Appendix A. Additional Information for RISC Systems. Problem determination procedures are provided by power-on self-tests (POSTs), service request numbers, and maintenance analysis procedures (MAPs).
SCSI Interface Card Power-On Self-Tests (POSTs) The SCSI interface card POSTs start each time power is switched on, or when a Reset command is sent from the using-system SCSI attachment. They check only the internal components of the SCSI interface card; they do not check any interfaces to other FRUs. If the POSTs complete successfully, control passes to the functional microcode of the SCSI interface card.
Using the SRN Table Important: You should have been sent here from MAP 2010: 2104 – START. Do not start problem determination from the SRN table; always go to “MAP 2010: 2104 – START” on page 44 first. 1. Locate the SRN in the table. If you cannot find a particular SRN in the table, go to the SRN list that is in the user or maintenance information for your using-system SCSI attachment. If you still cannot find the SRN, you have a problem with the diagnostics, the microcode, or the documentation.
The SRNs SRN 807-12X FRU List Problem Fan-and-power-supply assembly (90%) (“Fan-and-Power-Supply Assemblies” on page 89) Description: A power supply has failed.

For information about the location codes that are used by the using system, see the Operator Guide for the using system. This section shows the location codes for the 2104.
System Service Aids If the 2104 is configured to the using system, service aids are available on that using system to help you service the 2104. This section briefly describes some of those aids, and tells how to use them. More details are given in the service information for the using system.
The Certify service aid takes approximately 10 minutes to run. SCSI Device Identification and Removal To run this service aid: 1. Go to the using system, select Diagnostic Operating Instructions, and follow the instructions to select the Function Selection menu. 2. Select Task Selection. 3. Select Identify and Remove Resource. 4. Select the device (enclosure or disk drive) from the displayed list. 5. Select the slot from the displayed list. 6. A menu is displayed.
Download Microcode to a Disk Drive or to a SCSI Interface Card The procedure for downloading microcode is similar for disk drives and for SCSI interface cards. For some configurations, additional actions are needed for SCSI interface cards (see also “Microcode Maintenance” on page 28). Downloading to Disk Drives 1. Go to the using system, select Diagnostic Operating Instructions, and follow the instructions to select the Function Selection menu. 2. Select Task Selection. 3. Select the Download Microcode.
Software and Microcode Errors Some failures might be caused by software errors or by microcode errors. If you think you have a software or microcode error: 1. Ensure that your system software, adapter microcode, disk drive microcode, and enclosure microcode are all at the latest levels. Information about the latest levels of software and microcode is given on the web support page (see “Web Support Page” on page 131). 2.
Collecting Errors To collect enclosure errors, add this cron job SES Healthcheck to the system cron table. Note: You must have root permissions to complete this procedure. Edit the system crons with the crontab -e command. At the bottom of the file, enter: 15 * * * * /usr/lpp/diagnostics/bin/run_ses_healthcheck 1> /dev/null 2> /dev/null For further information about the crontab command, see the web page at: http://www.rs6000.ibm.com/doc_link/en_US/a_doc_lib/cmds/aixcmds1/crontab.
Configuring a Disk Drive Module to the Using System If you have just installed a new disk drive module, and want to change the hdisk number, do the following: 1. Remove the new hdisk number by giving the command: rmdev -l [hdisknumber] -d where [hdisknumber] is the hdisk number that you want to remove (for example, hdisk12). 2.
