Before operation
This chapter describes what you should understand before operation.
Avoiding trouble
Bundled Software

1-2 Before operation
Hitachi Compute Rack 210H User’s Guide
Avoiding trouble
This section describes the requirements for daily maintenance in order to avoid
trouble that might occur during system unit operation.
System error check
If some error occurs with the system unit, an error message might be displayed.
To resolve trouble early, verify such alerts immediately.
Hardware errors
Perform error monitoring based on the ERROR LED of the system unit.
See Fault detection on page 2-2 and Operation monitoring on page 2-8
Software errors
Periodically monitor a software error event log. A software error, if one occurs,
is recorded on the event log. For verification of the event log of software
attached to the system unit, see the individual software manuals.
See Bandled software on page 1-5
Consistency check
In a disk array, a re-assign (data migration to a reserved area) is performed if a
bad block (inaccessible area) is detected on the HDD during the read/write
process. However, if a bad block exists in the mirror data part as well as in the
area not accessed for daily operations, no alternation process is performed. If
the HDD fails in such a state, data in the bad block cannot be rebuilt normally and
thus might be lost because mirror data cannot be read.
The disk array of the system unit is equipped with a patrol read function that has
been set to the factory default so it can verify or fix the HDDs periodically.
Therefore, there is no need to conduct a consistency check periodically.

Before operation 1-3
Hitachi Compute Rack 210H User’s Guide
Network Security
Recent years have seen an increase in attacks on systems by computer viruses
and in data falsification or leaks by hacking, resulting in more serious damage.
Infection by computer viruses not only affects your own system unit (victim) but
also might inflict damage on the unspecified number of targets through networks
(victimizer). In most cases, it is often said that inflection is caused by careless
downloading of data or use of data media of unknown origin. Effective means to
prevent infection include installation of anti-virus software or firewall for blocking
illegal access.
We recommend introducing preventive means simultaneously whenever a
network connection is established. Also, security can be maintained by keeping
the anti-virus software up-to-date. However, this does not mean that the
anti-virus software can always prevent infection with computer viruses. It
becomes important to establish and operate a system to prevent infection with
such viruses.
Some computer viruses send their own copies one after another to a
connected network. If your computer is infected, we recommend
disconnecting your LAN cable immediately and isolating the computer
from the network in order to prevent secondary infection.
System scan
Periodically check if computer viruses are hidden. It is convenient to use
anti-virus software’s scheduling function that enables automatic scanning
periodically.
Downloading the latest date
It is essential to always update anti-virus software in order to address
computer viruses that evolve on a daily basis. A virus pattern file and the
version of anti-virus software are included as the data to be updated. No
computer viruses can be found or eliminated if neither the pattern file nor the
software version responds to the virus invaded. We recommend establishing
an environment where your anti-virus software can be updated automatically
and periodically. See the manual that comes with your anti-virus software for
more details on how to use the anti-virus software.
Windows update check
If Microsoft Windows operating system (OS) is in use, Microsoft Corporation has
released an additional program to fix errors or vulnerability of its Windows OS.
Please visit the Windows Update website to confirm and install update programs
periodically.
Windows Update Website：http://windowsupdate.microsoft.com
Windows Update is also accessible from your Windows start menu.

1-4 Before operation
Hitachi Compute Rack 210H User’s Guide
Storing backup data
For storage devices such as HDD, or data media such as USB and memory, an
incorrect operation such as a failure or wrong formatting might lose important
data unexpectedly. If system data (data contained in Windows folders) are
destroyed, it becomes necessary to reinstall or set up the OS or applications and
thus it will take a long time to recover the system. To take proper measures,
backup data can be stored on tape or similar media to restore the system to its
most previous working state if data loss occurs. It is also possible to restore the
system to normal by creating system information backup data if system data
become lost or corrupted. We recommend backing up the system data
periodically.
For details on how to create and restore backup data, see the Windows Help or
visit the Microsoft website and search the page of backup technical information.
If backup software is used, see the manual that comes with the software.

Operational trouble
In case of trouble or unfamiliar matters of operation, see Solving problems on
page 6-2.

Hitachi Compute Rack 210H User’s Guide
Bundled Software
Install and use the following software program bundled with the system unit.
MegaRAID Storage Manager
This utility is necessary to manage disk array devices.
If this utility is not installed, no HDD failure can be detected, which will cause a
double failure and loss of data.
For details about using this utility, see MegaRAID Storage Manage Instruction
Manual.
Hardware Maintenance Agent
The Hardware Maintenance Agent is a utility necessary for maintenance of the
system unit. If a failure occurs on the system unit, this utility analyzes such a
failure automatically, thus facilitating identification of this failure and shortening
system recovery time.
For details about using this utility, see Hardware Maintenance Agent Windows
Edition User’s Guide.

●Each code can be retained and
displayed even in the standby
state (with AC cord connected
and POWER switch OFF).
●The previous code is cleared
when the power is turned on
(POWER switch is turned on).
3 OS event log
●Records an event as a system log, a
security log or an application log.
●Stores an event log generated at a
system level or an application
leveling the following directory, as
well as an error message:
●%SystemRoot%\SYSTEM32\config
The logs can be referenced by
using an event viewer.

ERROR LED
The Baseboard Management Controller (BMC), an onboard management
controller of the system unit, turns on the ERROR LED on the front of the system
unit if a hardware error occurs, such as a HDD error, a fan error, a power supply
error, and others.
The sensors having a threshold are lit up in the Critical State (a critical state of
the system unit). But do not turn on in the Uncritical State (a state in which a
component has a failure under redundancy).
MAINTENANCE LEDs
You can choose what is displayed as the operation status from the event code,
the POST code and the power consumption using a SERVICE switch.
A combination of ON/OFF selections of MODE0 LED, MODE1 LED, and SERVICE
LED determines what is currently displayed.
A combination of ON/OFF selections of MODE0 LED, MODE1 LED, and the
SERVICE LED determines what the MAINTENANCE LEDs indicate as follows:
Table 2-2: What the MAINTENANCE LEDs indicate
SERVICE LED MODE0 LED MODE1 LED What the MAINTENANCE
LEDs indicate
Off Off Off Event code
On Off On POST code
Off On On Power consumption
When you press a SERVICE switch, the MAINTENANCE LEDs change as follows.

Event code
The operation status of the system unit is displayed. Under normal operation,
all LEDs are OFF. If an error occurs, the LED corresponding to the component
where the error occurred is turned on.
Table 2-3: Event code indicate
Post code
The POST code of the system BIOS is displayed as two-digits where one-digit
consists of four bits. The LEDs 1 through 4 indicate the upper digit.
The LEDs 5 through 8 indicate the lower digit. The smaller the LED number is
the higher bit the LED represents.
If Power On Self Test (POST) is successful, only LEDs 1, 3, 5, 6, and 7 are
turned on. (That means "AE" is displayed.)
Figure 2-3: Post code indicate
The MAINTENANCE LEDs keep the display of the POST code unless
the AC power source is turned off. In addition to that, when an error
occurred, the MAINTENANCE LEDs keep the display of the event
code. When the power is turned on, the display gets cleared.

Power consumption
The rough estimate of the current power consumption of the system unit (W)
is displayed.
The numbers of turned-on MAINTENANCE LEDs indicate the power
consumption, as follows:
Table 2-4: Power consumption indicate
MAINTENANCE LED Power consumption
All Off Less than 200 W
Only 1 is On 200 W or more and less than 250 W
1 and 2 are On 250 W or more and less than 300 W
1 through 3 are On 300 W or more and less than 350 W
1 through 4 are On 350 W or more and less than 400 W
1 through 5 are On 400 W or more and less than 450 W
1 through 6 are On 450 W or more and less than 500 W
1 through 7 are On 500 W or more and less than 550 W
1 through 8 are On 550 W or more
The indicated power consumption value is not accurate. Use this
value as a just reference.

OS event log
An event log is the data required for investigation in Windows OS. Events that
have occurred inside the OS are recorded in the event log in chronological order.
The "Event Viewer" is provided as a management tool for referencing the event
log. In the Windows Start menu, click Start > Administrative Tools > Event
Viewer. For details, see the Event Viewer's help.
Event types include information, warnings and errors. It has been confirmed that
events are temporary or known instances even if they are errors or warnings. In
case of an error or a warning, see Hitachi Compute Rack 210H/220H Windows
Installation Guide or the manual that comes with the software being used.
For general Windows instances, verify the support technical information
(Knowledge Base) of Microsoft Corporation.
Microsoft Support Online: http://support.microsoft.com /
STOP message and memory dump
If the Windows OS has been trapped in a critical state for some reason, a blue
screen appears and a STOP message is displayed. At this time, Windows can
save the STOP message information in a dump file. This is referred to as a
memory dump.
If Windows is hung up, the cause of a failure can be narrowed down by analyzing
the memory dump.
The following three types of memory dumps are available:
Minimum memory dump (64 KB)
Kernel memory dump
Full memory dump
The full memory dump is effective in fault investigation. The other dumps are
extremely difficult to analyze because of less information contained therein.
The following conditions are required for full memory dump. When you configure
partitions, be aware of acquisition of a full memory dump during system
construction.
A page file is in the Windows-installed drive (C drive).
A page file is larger than physical memory installed + 400 MB.
Free space for a dump file should exist in the C drive.
For details on the setting of a page file (virtual memory), see Windows help.
