Chapter 1 Electrostatic Discharge (ESD) Precautions 5

Electrostatic Discharge (ESD) Precautions

CAUTION Before you handle a component, make sure that

!

you have taken electrostatic discharge precautions:

• The minimum requirement is an anti-static wrist strap,
which must be connected to a hard ground to be
effective. We recommend that you remove component s
from their packaging and place them on an ESD-qualified
table that is equipped with ground points for wrist straps.

• Static charges can build up rapidly on rolling carts. If a
hardware component is transported by cart, the cart
should be grounded by a drag chain on an ESD floor. If
there is no ESD cart available or ESD floor , you should
first ground yourself before you touch a component that
has been transported on a cart.

CHAPTER 2

Service the Pillar Axiom Storage System

Introduction to System Service Procedures

Most service procedures require Guided Maintenance, which
is accessed through the Axiom Storage Manager. This
chapter:

7

• Tells you how to initiate Guided Maintenance.

• Provides service procedures to help you replace
hardware components and field replaceable units
(FRUs).

Pillar Data Systems Confidential

Chapter 2 Initiate Guided Maintenance 8

Initiate Guided Maintenance

To maintain or restore reliability to an Axiom system, you
sometimes need to replace a hardware component. To
replace a hardware component, you must use Guided
Maintenance. You access Guided Maintenance through the
Axiom Storage Manager, the graphical user interface (GUI),
in one of three ways:

• In the Health section, click the type of hardware of
interest and locate a particular FRU. To enter Guided
Maintenance for that FRU, select the link.

• Click the system status icon on the far left side of the
status bar, which takes you to the above Health section.

• In the Support section, click the Slammer or Brick link in
the navigation pane and locate a particular FRU. To enter
Guided Maintenance for that FRU, select the link.

Although you can enter Guided Maintenance in any of those
ways, procedures in this guide assume the first. To initiate

Identify the Target FRU (Optional)

This procedure is Step 1 of Guided Maintenance. If you know
which FRU to replace, you may still want to perform this step
to verify the identity of the target FRU. Though this step is not
required, it is highly recommended.

Important! Axiom storage systems ensure continuous data
access during single points of failure. A second failure,
including operator errors, may cause system failure. Use care
and take full advantage of Guided Maintenance features.

For Slammers, Guided Maintenance blinks all LEDs (except
those for power supplies) to identify a target FRU. Both the
Identify and Reverse Identify buttons are available for
Slammers.

For Bricks, Guided Maintenance blinks all LEDs to identify
the FRU except for the fault-related LEDs:

• Fault LED on the bezel.

• Power LED that is adjacent to the triangular icon on the
power supply.

• FLT LED on the RAID controller.

• Left LED on the Enclosure Services (ES) module.

• FLT LED on the Spare disk drive.

Fault-related LEDs light solid amber.
Both the Identify and Reverse Identify buttons are available

for Bricks.

• Click the Close button to discontinue Guided
Maintenance.

Prepare the System for FRU Replacement

This procedure is Step 2 of Guided Maintenance.
Before Guided Maintenance prompts you to replace a FRU,

the Pillar Axiom system performs some preparatory steps.
FRU replacement procedures explain what these steps are.

Note: In some replacement procedures, the software powers
down one or both Slammer control units (CUs). The service
technician can then safely unplug the CU power cords.

To prepare the system for FRU replacement:

1 On the Prepare System page, click the Prepare System

button.

Fail Back the Control Unit (Optional)

If you have not selected Enable Automatic Recovery, this
procedure becomes Step 4 of Guided Maintenance in which
failback is manually controlled. However, if you have selected
Enable Automatic Recovery, Guided Maintenance
automatically fails back the target Slammer CU from its
partner.

You can override automatic failback by not selecting the
Enable Automatic Recovery option. When this option is not
selected, Guided Maintenance displays the Resume button
to allow you to control manually when the failback occurs.

To fail back the control unit (CU) from its partner, click the
Resume button.

Verify The Status of the Replacement FRU

In all cases of FRU replacement (other than that for bezels),
after you have replaced a FRU, Guided Maintenance:

• Displays the Verify page.

• Continually probes the FRU for its status.

When all is well, Guided Maintenance reports a Normal
status for the FRU.

Note: Guided Maintenance continues to probe for status until
the Verify page is closed.

To close the Verify page, click the Next or Finish button.
Which button displays depends on whether a system restart
is required.

System-Wide Service Procedures

This section provides system-wide procedures that you might
need to perform while you service a Pillar Axiom system.

Back Up Data

Regular backups are prudent IT practice. When you service
hardware components that directly affect user data paths, we
highly recommend that you first back up all user data to
external media.

Important! Extraordinary system hardware changes (such
as replacing a Brick) and software configuration changes
(such as resetting the system to a factory-fresh state) and all
other modifications not specifically mentioned in this
document should only be attempted after consultation with
Technical Support. A backup of data should always be done
prior to all but routine maintenance actions.

Pillar Data Systems Confidential

Chapter 2 System-Wide Service Procedures 18

Full system backups to external media must be performed
when you want to perform any of the following actions:

• Replace a Brick chassis.
Important! Contact Technical Support so that a Brick

backplane replacement can be tailored for your system.

• Clear the system configuration. This action requires an
encrypted system key that Technical Support can supply.
This action destroys access to all user and system data.

CAUTION Before you clear the system configuration,

!

consult with Technical Support to avoid the risk of losing
system configuration data.

To back up the system, refer to one of these documents:

• The NDMP section of Administrator’s Help and to the
documentation for your NDMP-based backup application.

• The dump and restore sections of Administrator’s Guide
to the CLI. The request names are PerformDump and
PerformRestore.

CHAPTER 3

Service the Pilot and Pilot FRUs

Introduction to Pilot Service Procedures

Each control unit (CU) within a Pilot management controller
contains:

24

• An operating system.

• Various Axiom applications.
These applications include the graphical user interface

(GUI), the command line interface (CLI), and Network
Data Management Protocol (NDMP) and Simple Network
Management Protocol (SNMP) support.

Pilot CU failure does not disrupt user data paths. User data
paths are supported entirely by Slammers. Even if both CUs
fail, the Axiom system continues to operate. If both CUs fail,
the system simply has no management interface. In this
condition, the Axiom system cannot:

• Respond to GUI or command line interface (CLI)
requests.

• Change configuration.

Pillar Data Systems Confidential

Chapter 3 Introduction to Pilot Service Procedures 25

• Cold start a CU.

• Notify administrators (through alerts) or Technical
Support (through Call-Home messages) of the problem.

• Accept new hardware into the system.

• Run backups.

• Run automatically scheduled work such as scheduled
snapshots.

When a single Pilot CU fails, any or all of the following
notification methods occur:

• If email and the Call-Home feature are configured and
enabled, a Call-Home message is sent to Technical
Support. A Technical Support Engineer initiates a service
call.

• If email and alerts are configured and enabled, an alert is
emailed to designated recipients.

• An event is written to the event log.

• Axiom Storage Manager displays a Failed status in the
Health pages.

Note: No Pilot LEDs blink, however, to indicate the failure.
There is no Guided Maintenance for Pilots. If the Pilot bezel

fails, you replace the bezel. If a single Pilot CU fails, you
replace the CU. You can replace the bezel and a failed CU
while the Axiom system is operational.

Insert a Pilot Control Unit

When you replace a Pilot control unit (CU), the existing Pilot
CU updates the replacement CU with this information:

• Public and private IP addresses

• Linux operating system

• Build number

• Pilot identity

When you cable the Pilot control unit (CU) replacement, refer
to the labels on the Ethernet cables to guide you.

For complete information on how to cable a Pilot CU into the
system, see Table 80, FRU cable table reference, in
Appendix C, Private Management Network and SSF Cable

Reference. Before you refer to those tables, see Figure 5,
Schematic of replaceable Pilot FRUs, to determine whether

the replacement CU is CU 0 or CU 1. The cabling tables in

Appendix C refer to these CU designations.

To insert a Pilot control unit (CU):

1 Place the Pilot CU onto the empty set of Pilot rack rails.

Hold the Pilot CU horizontally to align and engage the

Chapter 3 Reset the Primary Password, Public IP, or Pilot Identity 36

Important! If you replaced a single Pilot CU, make sure that

the surviving CU has been powered on for at least one
minute before you perform the next step. If you replaced both
Pilot CUs at the same time:

• Power on the top replacement CU first.

• Wait for at least one minute.

• Power on the bottom replacement CU.

Powering up Pilot CUs in a staged manner avoids contention
between them as to which is CU 0 and which is CU 1.

6 Attach the power cable to the CU.
7 Add the Pilot bezel.

Reset the Primary Password, Public IP, or Pilot Identity

Conditions might require certain configuration parameters to
be reset. For example, the Primary System Administrator
may have forgotten the login password or incorrectly set an
IP address. You can use special recovery files to reset these
parameters to their factory defaults:

• The Primary System Administrator password.

• Certain TCP/IP settings (such as IP address, netmask,
and gateway) for the management console network.

Pillar Data Systems Confidential

Chapter 3 Reset the Primary Password, Public IP, or Pilot Identity 37

• The internal identity of a Pilot control unit (CU). If the
proper power-up sequence for a replacement Pilot CU
was not followed, both CUs may contend as to which is
CU 0, which requires the internal ID of one of them to be
reset.

Parameter reset is accomplished by insertion of a USB key
that contains the recovery file(s). The figure below shows a
USB key connected to a Pilot USB port.

Figure 12 USB key in a Pilot control unit

Note: The displayed Pilot CUs are representative. The CUs
that are installed in your system may differ slightly.

Customer Service provides a particular recovery file that the
customer downloads into a USB key. This recovery file is
specific for a particular configuration parameter and will reset
that parameter to the factory default.

Recovery files are encrypted with the customer's system
serial number and can be used only by that customer on a
specific Pillar Axiom system.

Pillar Data Systems Confidential

Chapter 3 Reset the Primary Password, Public IP, or Pilot Identity 38

The USB key can contain any combination of recovery files,
all of which will be read by the Pilot’s operating system. The
USB key and its recovery files can be reapplied, if necessary.

After a recovery file is applied, the Pilot CU may restart.
To reset a configuration parameter:

1 Call Technical Support and describe the problem.

Technical Support sends the appropriate text file to reset
the configurations parameter(s).

2 Follow the instructions that you get from Technical

Support to write this text file to a USB key.

3 Insert the USB key into one of the USB ports on one of

the Pilots.
The operating system on the Pilot control unit detects the

USB key and runs a script that is based on the keyword
that is encrypted in the recovery file. This script performs
the corrective action, which takes only a few seconds.

4 When the Pilot control units report a Normal status,

remove the USB key.

Note: If the IP address of a Pilot CU is reset, it will be set to

10.0.0.3 or 10.0.0.4 and the shared management IP will be
set to 10.0.0.2. If the administrator account password is
reset, it will be set to pillar.

Service the Slammer and Slammer FRUs

Introduction to Slammer Service Procedures

When a Slammer storage controller or one of its field
replaceable units (FRUs) fails, any or all of the following
notification methods occur:

• If the email and Call-Home features are configured and
enabled, a Call-Home message is sent to Pillar Data
Systems. A service call is automatically initiated.

• If email and alerts are configured and enabled, an alert is
emailed to designated recipients.

• An event is written to the event log.

• Axiom Storage Manager displays a Failed status in the
Health pages.

• One or more LEDs blink (except for power supply LEDs).

Pillar Data Systems Confidential

Chapter 4 Introduction to Slammer Service Procedures 40

A Slammer contains two control units (CUs). Each CU
contains a number of FRUs, some of which you can replace
while the CU is powered and running. Others you can replace
only after the CU has been powered down and power has
been removed from the CU power supply inlets.

When you need to replace one of the Slammer FRUs that
cannot be replaced while the CU is powered up, Guided
Maintenance prepares the system and powers down the
affected CU gracefully. While you replace a target FRU, the
partner CU continues to support all user data paths.

Important! If you need to power off a Slammer CU for more
than 12 hours, remove its battery.

Table 9 provides information about each FRU and the effect

that its replacement has on the CU. This table:

• Identifies the FRUs within a Slammer.

• Indicates whether AC power needs to be removed.

• Indicates the operating state of the target CU in the
Slammer. The state can be normal, conservative mode,
or failed over .

Note: In conservative mode, the Axiom system does not
depend on battery-backed memory in the target CU. The
system flushes cached data and commits all disk writes
to the storage array.

• Lists the replacement tasks for those FRUs.

Each Slammer control unit (CU) has a single battery that
provides backup power to two of the six memory module slots
on the motherboard. The figure below shows a battery.

The battery charger within a Slammer CU keeps the battery
charged. The battery can sustain power to the two memory
slots for 72 hr for systems with 3 or 6 GB of memory per CU
and for 48 hr for systems with 12 GB of memory per CU.

Important! If a power failure exceeds the above 72- or 48-hr
limit, the battery could be overly discharged. In this case, you
should replace the battery.

Important! After recovery from a power failure and while the
battery is charging, the system operates in conservative
(write-through cache) mode. The system stays in this mode
until the battery charge reaches 80% of battery capacity,
which may take up to 12 hr of normal power. If the battery is
severely discharged, recharge time can take up to 18 hr or
more. If the battery takes longer that 18 hr to reach a full
charge, you should replace the battery.

Replace Slammer Motherboard Trays

Motherboard replacement requires you to replace the entire
motherboard tray. Motherboard replacement in a Slammer
disrupts the normal operation of an Axiom system. To allow
the replacement of the motherboard tray in a target control
unit (CU), the system induces failover for the target CU to its
partner CU and powers down the target CU.

Pillar Data Systems Confidential

Chapter 4 Replace Slammer Motherboard Trays 62

Important! Even though failover transfers services and data

paths to the partner control unit (CU), your network topology
might make those services and data paths inaccessible.
Before you start the replacement procedure, make sure that
your network is configured to allow the data paths to switch
over to the partner CU.

After you replace the motherboard tray and reattach the
power cords to the target CU, the Axiom system powers up
the target CU and induces failback for the target CU.

The motherboard is attached to a motherboard tray, which
can also hold a pair of fan modules and a battery. Together,
these FRUs are called a motherboard assembly. The figure
