General safety
When you service the SAN Volume Controller, redundant ac-power switch, or the uninterruptible power
supply, follow general safety guidelines.
Use the following general rules to ensure safety to yourself and others:
v Observe good housekeeping in the area where the devices are kept during and after maintenance.
v Follow the guidelines when lifting any heavy object:
1. Ensure that you can stand safely without slipping.
2. Distribute the weight of the object equally between your feet.
3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift.
4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the
muscles in your back. Do not attempt to lift any objects that weigh more than 18 kg (40 lb) or objects that
you think are too heavy for you.
v Do not perform any action that causes a hazard to the customer, or that makes the equipment unsafe.
v Before you start the device, ensure that other service representatives and customer's personnel are not
in a hazardous position.
v Place removed covers and other parts in a safe place, away from all personnel, while you are servicing
the unit.
v Keep your tool case away from walk areas so that other people will not trip over it.
v Do not wear loose clothing that can be trapped in the moving parts of a device. Ensure that your
sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it.
© Copyright IBM Corp. 2003, 2010 xiii
v Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconducting clip,
approximately 8 cm (3 in.) from the end.
v Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing.
Remember: Metal objects are good electrical conductors.
v Wear safety glasses when you are: hammering, drilling, soldering, cutting wire, attaching springs,
using solvents, or working in any other conditions that might be hazardous to your eyes.
v After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device
that is worn or defective.
v Reinstall all covers correctly after you have finished servicing the unit.
Electrical safety
Observe these rules when working on electrical equipment.
CAUTION:
Electrical current from power, telephone, and communication cables can be hazardous. To avoid
personal injury or equipment damage, disconnect the attached power cords, telecommunication
systems, networks, and modems before you open the machine covers, unless instructed otherwise in
the installation and configuration procedures. (26)
Important: Use only approved tools and test equipment. Some hand tools have handles covered with a
soft material that does not insulate you when working with live electrical currents. Many customers have,
near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic
discharges. Do not use this type of mat to protect yourself from electrical shock.
v Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an
electrical accident occurs, you can then operate the switch or unplug the power cord quickly.
v Do not work alone under hazardous conditions or near equipment that has hazardous voltages.
v Disconnect all power before the following activities:
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing main units
v Before you start to work on the unit, unplug the power cord. If you cannot unplug it, ask the customer
to power off the wall box that supplies power to the device and to lock the wall box in the off position.
v If you need to work on a device that has exposed electrical circuits, observe the following precautions:
– Ensure that another person, familiar with the power-off controls, is near you.
Remember: Another person must be there to switch off the power, if necessary.
– Use only one hand when working with electrical equipment that has the power turned on; keep the
other hand in your pocket or behind your back.
Remember: There must be a complete circuit to cause electrical shock. By observing the previous
rule, you might prevent a current from passing through your body.
– When using testers, set the controls correctly and use the approved probe leads and accessories for
that tester.
– Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from grounds such as
metal floor strips and machine frames.
Observe the special safety precautions when you work with very high voltages; these instructions are
in the safety sections of maintenance information. Use extreme care when measuring high voltages.
v Regularly inspect and maintain your electrical hand tools for safe operational condition.
v Do not use worn or broken tools and testers.
xiv IBM SAN Volume Controller Hardware Maintenance Guide
v Never assume that power has been disconnected from a circuit. First, check that power has been powered
off.
v Always look carefully for possible hazards in your work area. Examples of these hazards are moist
floors, nongrounded power extension cables, power surges, and missing safety grounds.
v Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is
conductive; such touching can cause personal injury and device damage.
v Do not service the following parts with the power on when they are removed from their normal
operating places in a device. (This practice ensures correct grounding of the units.)
– Power supply units
– Pumps
– Blowers and fans
– Motor generators
– And similar units
v If an electrical accident occurs:
– Use caution; do not become a victim yourself.
– Switch off power.
– Send another person to get medical aid.
Inspecting the SAN Volume Controller for unsafe conditions
Use caution when working in any potential safety hazardous situation that is not covered in the safety
checks. If unsafe conditions are present, determine how serious the hazards are and whether you can
continue before you correct the problem.
Before you start the safety inspection, make sure that the power is off, and that the power cord is
disconnected.
Each device has required safety items installed to protect users and IBM service personnel from injury.
This guide addresses only those items.
Important: Good judgment must also be used to identify potential safety hazards due to the attachment
of non-IBM features or options not covered by this inspection guide.
If any unsafe conditions are present, you must determine how serious the apparent hazard could be and
whether you can continue without first correcting the problem. For example, consider the following
conditions and their potential safety hazards:
Electrical hazards (especially primary power)
Primary voltage on the frame can cause serious or lethal electrical shock.
Explosive hazards
A damaged CRT face or a bulging capacitor can cause serious injury.
Mechanical hazards
Loose or missing items (for example, nuts and screws) can cause serious injury.
To inspect each SAN Volume Controller node for unsafe conditions, perform the following steps. If
necessary, see any suitable safety publications.
1. Turn off SAN Volume Controller and disconnect the power cord.
2. Check the frame for damage (loose, broken, or sharp edges).
3. Check the power cables using the following steps:
Safety and environmental notices xv
a. Ensure that the third-wire ground connector is in good condition. Use a meter to check that the
third-wire ground continuity is 0.1 ohm or less between the external ground pin and the frame
ground.
b. Ensure that the power cord is the appropriate type, as specified in the parts listings.
c. Ensure that the insulation is not worn or damaged.
4. Check for any obvious nonstandard changes, both inside and outside the unit. Use good judgment
about the safety of any such changes.
5. Check inside SAN Volume Controller for any obvious unsafe conditions, such as metal particles,
contamination, water or other fluids, or marks of overheating, fire, or smoke damage.
6. Check for worn, damaged, or pinched cables.
7. Ensure that the voltage that is specified on the product-information label matches the specified
voltage of the electrical power outlet. If necessary, verify the voltage.
8. Inspect the power-supply assemblies and check that the fasteners (screws or rivets) in the cover of the
power-supply unit have not been removed or disturbed.
9. Before connecting SAN Volume Controller to the storage area network (SAN), check the grounding.
External device check
Ensure that you perform an external device check before you install or service the SAN Volume
Controller.
To conduct an external device check, perform the following steps:
1. Verify that all external covers are present and are not damaged.
2. Ensure that all latches and hinges are in the correct operating condition.
3. If SAN Volume Controller is not installed in a rack cabinet, check for loose or broken feet.
4. Check the power cord for damage.
5. Check the external signal cable for damage.
6. Check the cover for sharp edges, damage, or alterations that expose the internal parts of the device.
7. Correct any problems that you find.
Internal device checks
Ensure that you perform an internal device check before you install or service SAN Volume Controller.
To conduct the internal device check, perform the following steps:
1. Check for any non-IBM changes that might have been made to the device. If any are present, obtain
the “Non-IBM Alteration Attachment Survey,” form number R009, from the IBM branch office.
Complete the form and return it to the branch office.
2. Check the condition of the inside of the device for any metal or other contaminants, or any
indications of water, other fluid, fire, or smoke damage.
3. Check for any obvious mechanical problems, such as loose components.
4. Check any exposed cables and connectors for wear, cracks, or pinching.
Checking the grounding of SAN Volume Controller, the uninterruptible
power supply, and the redundant ac-power switch
Ensure that you understand how to check the grounding of a SAN Volume Controller, the uninterruptible
power supply, and the optional redundant ac-power switch feature.
To test the grounding of a SAN Volume Controller node, perform the following steps. Follow the steps
for the SAN Volume Controller configuration that you are using. Before you start, confirm that you know
xvi IBM SAN Volume Controller Hardware Maintenance Guide
the SAN Volume Controller model type, the uninterruptible power-supply type, and whether you are
using redundant ac power. Determine the location of the signal cables that are attached to the SAN
Volume Controller.
When you are asked to test the grounding continuity, use your local procedures to perform the test. The
test is successful if the measured resistance is 0.1 ohm or less.
Attention: Some electrical circuits can be damaged if the external signal cables are present at the SAN
Volume Controller while it is undergoing a grounding test.
1. Ensure that the SAN Volume Controller node is powered off. See MAP 5350: Powering off a SAN
Volume Controller node in the IBM System Storage SAN Volume Controller 2145 Troubleshooting Guide.
2. If the uninterruptible power supply is a 2145 UPS, ensure that other SAN Volume Controller nodes
that are powered from the uninterruptible power supply are powered off.
3. Use the power button to power off the uninterruptible power supply.
4. Disconnect all signal cables from the SAN Volume Controller node, which includes the following
cables:
v The fibre-channel cables
v The Ethernet cable or cables
v The serial cable that is connected to the uninterruptible power supply
5. Disconnect all signal cables from the uninterruptible power supply. If the uninterruptible power
supply is a 2145 UPS, there might be multiple signal cables.
6. If the uninterruptible power supply is a 2145 UPS, disconnect any power cables that are connected to
SAN Volume Controller nodes, except the one that is being tested.
7. If redundant ac power is not used, disconnect the uninterruptible power-supply power cable from
the site power-distribution unit.
8. If redundant ac power is used, turn off any SAN Volume Controller that is being supplied from the
redundant ac-power switch, and remove the power cable to this system from the redundant
ac-power switch.
9. If redundant ac power is used, disconnect both input power leads from the site power distribution
units.
10. If redundant ac power is not used, test the grounding continuity between a conductive area on the
SAN Volume Controller frame and the ground pin on the plug of the uninterruptible power-supply
input-power cable.
11. If redundant ac power is used, test the grounding continuity between a conductive area on the SAN
Volume Controller frame and the ground pin on the plug of the main power cable of the redundant
ac-power switch. If the test is successful, test the grounding continuity between a conductive area on
the SAN Volume Controller frame and the ground pin on the plug of the backup power cable of the
redundant ac-power switch. Both tests must be successful.
12. After you have completed testing the grounding continuity, perform one of the following procedures,
depending on the outcome of the test.
v If the test is successful, reconnect any cables that were removed, and power on any
uninterruptible power-supply units and SAN Volume Controller nodes that were powered off.
v If the test was not successful, ensure that all cables are securely connected. If the test still fails, test
the individual system components. Before you test the individual components, remove all cables
from the components. If any component test fails, replace the component. After each component
has been tested and the failing ones have been replaced, repeat the complete system test by
returning to step 1.
Test the components in the following order:
a. The SAN Volume Controller node, from the frame to the ground pin of the input power
receptacle
Safety and environmental notices xvii
b. The uninterruptible power supply from the ground pin of the input power receptacle to the
ground conductor of the output power receptacle
c. If used, the redundant ac-power switch from the ground pin of the main input power
receptacle to the ground conductor of the output power receptacle, and from the ground pin of
the backup input power receptacle to the ground conductor of the output power receptacle
d. The SAN Volume Controller node to uninterruptible power-supply power-cable assembly,
between the two ground conductors of the power cable
e. The uninterruptible power-supply input-power cable, between the two ground conductors of
the power cable
f. If used, the redundant ac-power switch main input-power cable, between the two ground
conductors of the cable

Inspecting the uninterruptible power supply for unsafe conditions
Ensure that you take the time to inspect the uninterruptible power supply for unsafe conditions.
Consider the following conditions and their potential safety hazards:
Electrical hazards (especially primary power)
Primary voltage on the frame can cause serious or lethal electrical shock.
Explosive hazards
A bulging capacitor can cause serious injury.
Mechanical hazards
Loose or missing items (for example, nuts and screws) can cause serious injury.
Use caution when working in a potential safety hazard that is not covered in the safety checks. If unsafe
conditions are present, determine how serious the hazards are and whether you can continue before you
correct the problem.
Using the following inspection checklist as a guide, inspect the uninterruptible power supply for unsafe
conditions. If necessary, see any suitable safety publications.
1. If any equipment has been damaged during the shipment, keep the shipping cartons and packing
materials.
2. To file a claim for the shipping damage, perform the following steps:
a. File with the carrier within fifteen days of receipt of the equipment.
b. Send a copy of the damage claim within fifteen days to your service support representative.
Uninterruptible power-supply requirements
Ensure that you comply with the requirements for the uninterruptible power supply.
The following list describes requirements for the 2145 UPS-1U:
v The voltage that is supplied to the 2145 UPS-1U must be 200-240 V single phase.
v The frequency that is supplied must be 50 or 60 Hz.
Note: The 2145 UPS-1U has an integrated circuit breaker and does not need external protection.
xviii IBM SAN Volume Controller Hardware Maintenance Guide
Attention:
v If the uninterruptible power supply is cascaded from another uninterruptible power supply, the source
uninterruptible power supply must have at least three times the capacity per phase and the total
harmonic distortion must be less than 5%.
v The uninterruptible power supply also must have input voltage capture that has a slew rate of no
more than 3 Hz per second.
Emergency power-off shutdown
The SAN Volume Controller and each uninterruptible power supply support emergency power-off (EPO)
shutdowns.
Handling static-sensitive devices
Ensure that you understand how to handle devices that are sensitive to static electricity.
Attention: Static electricity can damage electronic devices and your system. To avoid damage, keep
static-sensitive devices in their static-protective bags until you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following precautions:
v Limit your movement. Movement can cause static electricity to build up around you.
v Handle the device carefully, holding it by its edges or frame.
v Do not touch solder joints, pins, or exposed printed circuitry.
v Do not leave the device where others can handle and possibly damage the device.
v While the device is still in its antistatic bag, touch it to an unpainted metal part of the system unit for
at least two seconds. (This action removes static electricity from the package and from your body.)
v Remove the device from its package and install it directly into your SAN Volume Controller, without
putting it down. If it is necessary to put the device down, place it onto its static-protective bag. (If your
device is an adapter, place it component-side up.) Do not place the device onto the cover of the SAN
Volume Controller or onto a metal table.
v Take additional care when you handle devices during cold weather because heating reduces indoor
humidity and increases static electricity.

Redundant ac-power switch parts
There is a single field-replaceable unit (FRU) assembly for the redundant ac power feature. It consists of
the switch and two input-power cables.
The redundant ac-power switch is an optional feature that makes the SAN Volume Controller nodes
resilient to the failure of a single power circuit. The redundant ac-power switch is not a replacement for
an uninterruptible power supply. You must still use a uninterruptible power supply for each node.
Figure 6 shows the redundant ac-power switch.

Chapter 2. Removing and replacing parts
You can remove and replace field-replaceable units (FRUs) from the SAN Volume Controller, redundant
ac-power switch, and uninterruptible power supply.
Each FRU has its own removal procedure. Sometimes you can find that a step within a procedure might
refer you to a different remove/replace procedure. You might want to complete the new procedure before
you continue with the first procedure that you started.
Remove or replace parts only when you are directed to do so by the IBM System Storage SAN Volume
Controller 2145 Troubleshooting Guide. Start all problem determination and repair procedures with MAP
5000.
Enabling concurrent maintenance
To allow concurrent maintenance, SAN Volume Controllers must be configured in pairs.
While one SAN Volume Controller is being serviced, the other keeps the I/O group operational. With
concurrent maintenance, all field-replaceable units (FRUs) can be removed, replaced, and tested on one
SAN Volume Controller while the SAN and host systems are powered on and doing productive work.
Attention: Do not remove the power from both SAN Volume Controllers unless the procedures instruct
you to do so.
Perform the following checks to verify that concurrent maintenance is enabled.
1. Confirm that no hosts have dependencies on the node.
When shutting down a node that is part of a cluster or when deleting the node from a cluster, you
can use either the management GUI or a command-line interface (CLI) command. In the management
GUI, click System Status. Click the correct node and click Manage to display all the volumes that are
dependent on a node. You can also use the node parameter with the svcinfo lsdependentvdisks CLI
command to view dependent volumes.
If dependent volumes exist, determine if the volumes are being used. If the volumes are being used,
either restore the redundant configuration or suspend the host application. If a dependent quorum
disk is reported, repair the access to the quorum disk or modify the quorum disk configuration.
2. Ensure that the host multipathing device drivers can fail over to the partner node.
Some host multipathing device drivers take a while to update after changes are made on the fabric.
Do not shut down a node or delete the node from a cluster if the partner node in the I/O group to
which the node belongs has not been online for more than 30 minutes.
If possible, check the status of the host multipathing device drivers before shutting down a node to
ensure that the device drivers can fail over to the partner node.
When shutting down the node, see MAP 5350 in the IBM System Storage SAN Volume Controller 2145
Troubleshooting Guide for a description of how to check for dependencies on the node during the
procedure to turn off the node.
When deleting a node from the cluster, see "Deleting a node from a cluster using the management GUI"
in the IBM System Storage SAN Volume Controller 2145 Troubleshooting Guide for a description of node
information to retain to avoid data corruption when adding the node back to the cluster, how to ensure
that the multipathing device driver does not rediscover any paths that are manually removed, and for
other considerations regarding dependent volumes.
© Copyright IBM Corp. 2003, 2010 19
For more information about working with dependent volumes, see the following topics:
v "Listing node-dependent VDisks (volumes) using the CLI" in the IBM System Storage SAN Volume
Controller 2145 Troubleshooting Guide
v "lsnodedependentvdisks" command description in the IBM System Storage SAN Volume Controller
Command-Line Interface User's Guide
Preparing to remove and replace parts
Before you remove and replace parts, you must be aware of all safety issues.
First, read the safety precautions in the IBM Systems Safety Notices. These guidelines help you safely work
with the SAN Volume Controller, redundant ac-power switch, and uninterruptible power supply.
Working inside the node with the power on
When you are servicing the SAN Volume Controller node, you might need to turn on the node while the
cover is off.
Attention: Static electricity that is released to internal components when the node is turned on might
cause the node to halt, which might result in the loss of data. To avoid this potential problem, always use
an electrostatic-discharge wrist strap or other grounding system when you work inside the node with the
power on.
You might be instructed to turn on the node and look at system-board LEDs while the cover is off.
Follow these guidelines when you work inside a node that is turned on:
v Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved shirts before working
inside the server; do not wear cuff links while you are working inside the node.
v Do not allow your necktie or scarf to hang inside the node.
v Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist watches.
v Remove items from your shirt pocket, such as pens and pencils, that could fall into the node as you
lean over it.
v Avoid dropping any metallic objects, such as paper clips, hairpins, and screws, into the node.

Removing the cable-retention bracket
The SAN Volume Controller models 2145-CF8, 2145-8A4, 2145-8G4, 2145-8F4, and 2145-8F2 provide a
cable-retention bracket, which ensures that the node does not mistakenly become unplugged from the
uninterruptible power supply.
Removing the SAN Volume Controller 2145-CF8 cable-retention brackets
You can remove the two SAN Volume Controller 2145-CF8 cable-retention brackets when removing the
power cords from the node.
DANGER
Multiple power cords. The product might be equipped with multiple power cords. To remove all
hazardous voltages, disconnect all power cords.
The SAN Volume Controller 2145-CF8 uses two toolless cable-retention brackets, one to retain each cable
from the uninterruptible power-supply to one of the two SAN Volume Controller 2145-CF8 power
supplies, as shown in Figure 22 on page 30.
Chapter 2. Removing and replacing parts 29

Figure 22. SAN Volume Controller 2145-CF8 cable-retention brackets
Each cable-retention bracket attaches to the back of the SAN Volume Controller 2145-CF8 node. The
brackets connect without screws.
This service action requires you to:
v Optionally, turn off the node.
v Disconnect the power cable that the retention bracket is on.
To remove a cable-retention bracket, perform these steps:
1. Read the safety information to which “Preparing to remove and replace parts” on page 20 refers.
2. Optional: Follow the procedure in MAP 5350 in the IBM System Storage SAN Volume Controller 2145
Troubleshooting Guide to verify that the node data is mirrored and synchronized, and that there are no
dependent volumes before turning off the node.
Important: If you decide to hot swap a power supply, and that is why you are removing the cable
retention bracket, use MAP 5350 to make all of the necessary checks that ensure that the partner node
in the I/O group can take over all I/O group operations, if necessary, and that there are no dependent
VDisks on the node. With the partner node available and no dependent VDisks on the node, you do
not lose access to data if this node accidentally powers off.
3. Pull back the cable-management arm if you are working from the rear of the rack, or slide the node
out of the rack to the fully extended rail position if you are working from the front.
4. When the node is completely turned off, from under the cable, carefully push the spring clip away
from the cable to free the cable-retention bracket from the handle on the power supply.
The spring clip is shown by 1 in Figure 22.
5. Pull both the bracket and the cable (2) away from the SAN Volume Controller 2145-CF8 power
supply.
6. Remove the cable-retention bracket from the power cord.
Removing the SAN Volume Controller 2145-8A4 cable retention bracket
The cable-retention bracket attaches to the back of the SAN Volume Controller 2145-8A4 node. It is
connected with one screw that already holds the rear plate of the power supply in place.
Remove the cable-retention bracket before you remove the SAN Volume Controller 2145-8A4 node from
the rack.
To remove the bracket from the node, perform the following steps:

Replacing the SAN Volume Controller in a rack
You must use caution when you replace the SAN Volume Controller in a rack.
Note: If you have recently replaced a field-replaceable unit (FRU) in the node, the repaired node
normally rejoins the cluster as soon as it is powered-on and has completed its self-tests. There are some
exceptions to this, such as when a disk drive has been replaced, or when for some other reason the node
has lost its identity or the integrity of its cluster metadata. Under these circumstances, the node goes
offline. If you are performing this repair under directed maintenance procedures, those procedures will

automatically restore the node to the cluster. If you are not performing the repair under directed
maintenance procedures, you might be required to delete and add the node back into the cluster.
