4 Installation

4.1 Installing a 2U 12-bay unit

You can install the unit in a four-post rack or system cabinet.
Observe the following:
– You can install the unit in either a square-hole or round-hole rack.
– If you are installing the unit in a cabinet not provided by Bosch, you must calculate the

thermal output of your equipment and compare the results with the target system
cabinet's thermal rating. You might need to remove the system cabinet doors to improve
airflow through the system cabinet.
For thermal rating information refer to the rack or system cabinet manuals provided by
the manufacturer.

– You must use only the screws that are provided in the kit.

Notice!

When installing the units, load the cabinet so as not to make it top-heavy. One approach is to
place the controller-unit in the middle portion of the cabinet while allowing room for
expansion units to be placed above and below the controller unit.

To install a 12-bay controller or expansion unit:

1. Determine where you want to install the unit in the rack or system cabinet.
Note: Whenever possible, install the units from the bottom of the rack up, so that you can
use the units underneath as a guide for installing the next set of rails.

2. Attach the rails to the rack or system cabinet as follows:

8.1 Replacing a drive in a 12-bay unit

The Recovery Guru in SANtricity System Manager monitors the drives in the unit and can notify
you of an impending drive failure or an actual drive failure. When a drive has failed, its amber
Attention LED is on. You can hot-swap a failed drive while the unit is receiving I/O operations.

Before you begin

– You have a replacement drive that is supported by Bosch for the controller unit or

expansion unit.

– You have an ESD wristband, or you have taken other antistatic precautions.

About this procedure

Use this procedure to replace a drive in the following controller units or expansion units:

Type Number of drives Type of drives

12-bay controller unit 12 3.5-inch SAS drives (or 2.5-inch SAS drives in

12-bay expansion unit 12

Drive numbering in a 12-bay controller unit or a 12-bay expansion unit

carriers)

Rules for handling drives

The drives are fragile. Improper drive handling is a leading cause of drive failure. Follow these
rules to avoid damaging the drives in your unit:
– Prevent electrostatic discharge (ESD)

– Keep the drive in the ESD bag until you are ready to install it.
– Do not insert a metal tool or knife into the ESD bag. Open the ESD bag by hand or

cut the top off with a pair of scissors.
– Keep the ESD bag and any packing materials in case you must return a drive later.
– Always wear an ESD wrist strap grounded to an unpainted surface on your storage

enclosure chassis. If a wrist strap is unavailable, touch an unpainted surface on your

storage enclosure chassis before handling the drive.

– Handle drives carefully

– Always use two hands when removing, installing, or carrying a drive.
– Never force a drive into a unit. Use gentle, firm pressure to completely engage the

drive latch.
– Place drives on cushioned surfaces, and never stack drives on top of each other.
– Do not bump drives against other surfaces.
– Before removing a drive, unlatch the handle and wait 30seconds for the drive to spin

down.
– Always use approved packaging when shipping drives.

– Avoid magnetic fields

– Keep drives away from magnetic devices. Magnetic fields can destroy all data on the

drive and cause irreparable damage to the drive circuitry.

To replace a drive observe the instructions in the following chapters:

4. After replacing a drive, page 34

8.1.1 Preparing to replace a drive

Before replacing a drive, check the Recovery Guru in SANtricity System Manager and complete
any prerequisite steps. Then, you can locate the failed drive.
To locate the failed drive:

1. If the Recovery Guru in SANtricity System Manager has notified you of an impending drive
failure, but the drive has not yet failed, follow the instructions in the Recovery Guru to fail
the drive.

2. If needed, use SANtricity System Manager to confirm you have a suitable replacement
drive.
– Select Hardware.
– Select the failed drive on the unit graphic.
– Click the drive to display the context menu, then select View settings.
– Confirm that the replacement drive has a capacity equal to or greater than the drive

you are replacing and that it has the features you expect.
For example, do not attempt to replace a hard disk drive (HDD) with a solid-state
disk (SSD). Similarly, if you are replacing a secure-capable drive, make sure the
replacement drive is also secure-capable.

3. If needed, use SANtricity System Manager to locate the drive within the storage unit.
– If the unit has a bezel, remove it so you can see the LEDs.
– From the drive's context menu, select Turn on locator light.

The drive's amber Attention LED blinks so you can identify which drive to replace.

8.1.2 Removing a drive

When removing a drive from a 12-bay controller unit or a 12-bay expansion unit, you must slide
the drive partly out of the unit and wait for the drive to spin down. Then, you can remove the
drive completely.
Before you begin:
– You have an ESD wristband, or you have taken other antistatic precautions.
– You have reviewed the .
To remove a drive:

1. Unpack the replacement drive, and set it on a flat, static-free surface near the unit. Save
all packing materials for the next time you need to send a drive back.

2. Press the release button on the failed drive. The release button is located at the left of
the drive.

3. Open the cam handle, and slide out the drive slightly.

4. Wait 30seconds.

5. Using both hands, remove the drive from the unit.

6. Place the drive on an antistatic, cushioned surface away from magnetic fields.

7. Wait 30seconds for the software to recognize that the drive has been removed.

Notice!

If you accidentally remove an active drive, wait at least 30seconds, and then reinstall it. For
the recovery procedure, refer to the storage management software.

8.1.3 Installing a drive

Install the replacement drive as soon as possible after removing the failed drive. Otherwise,
there is a risk that the equipment might overheat.
To install a drive:

1. Open the cam handle.

2. Using two hands, insert the replacement drive into the open bay, firmly pushing until the
drive stops.

3. Slowly close the cam handle until the drive is fully seated in the midplane and the handle
clicks into place.
Note: Depending on your configuration, the controller might automatically reconstruct
data to the new drive. If the unit uses hot spare drives, the controller might need to
perform a complete reconstruction on the hot spare before it can copy the data to the
replaced drive. This reconstruction process increases the time that is required to
complete this procedure.

8.1.4 After replacing a drive

After replacing a drive, you must confirm that the new drive is working correctly.
To confirm that the drive is working correctly:

1. Check the Power LED and the Attention LED on the drive you replaced.

canister), you turn off power, disconnect the power cord, and slide the part out of the shelf.
To remove a power-fan canister:

1. Put on antistatic protection.

2. Unpack the new power supply, and set it on a level surface near the drive shelf.
Save all packing materials for use when returning the failed power supply.

3. Turn off the power supply and disconnect the power cables:
– Turn off the power switch on the power supply.
– Open the power cord retainer, and then unplug the power cord from the power

supply.

– Unplug the power cord from the power source.

4. Squeeze the latch on the power supply cam handle, and then open the cam handle to
fully release the power supply from the midplane.

5. Use the cam handle to slide the power supply out of the system.
As you remove the power supply, a flap swings into place to block the empty bay, helping
to maintain air flow and cooling.
Note: When removing a power supply, always use two hands to support its weight.

8.2.3 Installing a power-fan canister

To install a power-fan canister:

1. Make sure that the on/off switch of the new power supply is in the Off position.

2. Using both hands, support and align the edges of the power supply with the opening in
the system chassis, and then gently push the power supply into the chassis using the cam
handle.
The power supplies are keyed and can only be installed one way.
Note: Do not use excessive force when sliding the power supply into the system; you can
damage the connector.

3. Close the cam handle so that the latch clicks into the locked position and the power
supply is fully seated.

4. Reconnect the power supply cabling as follows:
Reconnect the power cord to the power supply and the power source.
Secure the power cord to the power supply using the power cord retainer.

5. Turn on the power to the new power-fan canister.

8.2.4 After replacing a power-fan canister

After replacing a power-fan canister, you must confirm that the new power-fan canister is
working correctly. Then, you can gather support data and resume operations.
To confirm that the power-fan canister is working correctly:

1. Check the green Power LED and the amber Attention LED on the new power-fan canister.
The green LED should be on and the amber LED should be off (see LEDs on the power-fan
canister, page 17).

2. From the Recovery Guru in SANtricity System Manager, select Recheck to ensure the
problem has been resolved.

3. If a failed power-fan canister is still being reported, repeat the steps in the following
sections:
– Removing a power-fan canister, page 37
– Installing a power-fan canister, page 38.

If the problem continues to persist, contact technical support.

4. Remove the antistatic protection.

5. Collect support data for your storage system (see Collecting support data for the storage
system, page 43).
Note: Collecting support data before and after replacing a component ensures you can
send a full set of logs to technical support in case the replacement does not resolve the
problem.

8.3.1 Seven-segment display sequence codes

Seven-segment display sequences enable you to understand errors and operational states of
the various components in your storage array. Each sequence shows a two-digit category
code, followed by a two-digit detail code. The category code appears at the start of a
sequence and the detail code follows the category code with more specific information about
the error. After each category code is displayed, the LED goes blank. Then the detail code
appears and disappears, and the entire sequence is repeated. For example, if there is a
power-on validation error during startup, you see the following codes displayed on the seven­segment display: SE, followed by Sx, in which SE is the category code and Sx is the detail
code.
When the seven-segment display sequence starts, the Diagnostic LED is on (green).
The following table includes the seven-segment display sequence codes and descriptions:

Category Category code Detail code

Startup error SE – 88: Power-on default

– dF: Power-on diagnostic fault
– Sx: Power-on validation error

Operational error OE – Lx: Lock-down codes

See Seven-segment display lock-down
codes.

Operational state OS – OL: Offline

– bb: Battery backup (operating on

batteries)

– OH: CPU temperature exceeds the

warning level

– CF: Component failure

Component failure CF – dx: Processor or cache DIMM

– Cx: Cache DIMM
– Px: Processor DIMM
– Hx: Host interface card
– Fx : Flash drive
– bl: Base controller card

Diagnostic failure dE – Lx: Lock-down codes

– See Seven-segment display lock-

down codes.

Category delimiter --

Note: The double
hyphen (--) is the
separator between
categorydetail
code pairs when
more than one pair
exists in the
sequence.

End-of-sequence delimiter Blank: The display

turns off at the end
of a sequence.
