System Configuration of
NEC Storage Manager
4-2 System Configuration of NEC Storage Manager
This chapter gives an overview of NEC Storage Manager.
Note: A personal computer on which
Microsoft Windows 2000 or Windows Server 2003
operates is called a ”PC” in this chapter. Windows
2000 and Windows Server 2003 are generically
called “Windows” in this chapter.
Overview
NEC Storage Manager consists of server and client functions.
The server function operates on a management server, and directly monitors the
disk arrays of the NEC Storage series connected through a LAN or FC (Fibre
Channel).
The client function operates on a PC connected with the management server
through a LAN, and provides the user with the monitoring and operation
features through the GUI.
NEC Storage Manager provides various features to operate the disk arrays of
the NEC Storage series. Figure 4-1 shows a system configuration sample using
NEC Storage Manager.

System Configuration of NEC Storage Manager 4-3
It is recommended that the management server and the NEC
Storage disk array should be connected through a LAN.
They can also be connected through a fibre channel. In this case,
however, if the business server is subjected to a high load,
contention may occur between application I/O and performance
monitoring, performance optimization, or data replication I/O.
The I/O path of each server also needs to be specified in the
Access Control setting. Thus, connection through a LAN from a
separate management server is safer than connection through FC.
If you connect the management server and the disk array through
a LAN, you need to set the network information (e.g., IP address)
for the disk array. Set the information correctly according to the
manual provided with the disk array.
NEC Storage Manager can monitor more than one disk array
simultaneously. However, do not use more than one NEC Storage
Manager to simultaneously monitor a single disk array.
If multiple NEC Storage Manager applications are used to monitor
a single disk array, a repeatedly noticed error or a conflict between
their statistical information of performance may cause operation
trouble.

Basic Functions of NEC Storage Manager
The basic functions of NEC Storage Manager include the following functions
required for operating disk arrays. Refer to Chapter 3 “Basic Functions” of
Section A in the “NEC Storage Manager User’s Manual ” for more information
on each function described below.
Configuration Display
The configuration display function is a basic function of NEC Storage Manager
that displays the configuration of physical resources making up a disk array,
and logical disks recognized by the business server. Since multiple disk array
configurations can be managed, the disk arrays can be centrally monitored in
the same view through the iSM client.
For details, refer to “Configuration Display” in Chapter 3 of Section A in the
“NEC Storage Manager User’s Manual”.
State Monitoring
The state monitoring function monitors the occurrences of the following events
in the disk arrays to be managed by NEC Storage Manager:
n State transition in components
n Changing of disk array names, logical disk names, and port names
n Configuration change
When detecting any of the above events, the state monitoring function reflects
information about the detected event onto the configuration management screen
of the iSM client. At the same time, the function outputs the message indicating
the event to various logs, and performs link processing such as execution of the
script file whenever the event is detected.
5-6 Functions of NEC Storage Manager
For details, refer to “State Monitoring” in Chapter 3 of Section A in the “NEC
Storage Manager User’s Manual”.
Nickname Setting
The nickname setting function is used via the iSM client to set the disk array
name, LD name (+ OS type), and port name for the disk array to be managed.
The disk array can be managed efficiently by matching the set information to
the identification information provided by the business server that operates the
disk array.
For details, refer to “Nickname Setting” in Chapter 3 of Section A in the “NEC
Storage Manager User’s Manual”.
Fault Monitoring
While iSM clients are connected, all iSM messages are output to the message
display area of the iSM client screen, which enables each iSM client to monitor
disk array errors. A display message is collected as a log file, and the
occurrence of the error is reported to the iSM clients matching the message
level in real time.
For details, refer to “Fault Monitoring” in Chapter 3 of Section A in the “NEC
Storage Manager User’s Manual”.
Log Output
The log output function outputs messages, which indicate iSM error
information and operation information, to various logs (operation log and
syslog under UNIX, and operation log and event log under Windows). For
details, refer to “Log Output” in Chapter 3 of Section A in the “NEC Storage
Manager User’s Manual”.
Event Link
The event link function takes action such as sending mail and starting a file (a
shell file under UNIX, and an executable file or batch file on the monitoring
server under Windows) according to the message contents. You can define link
processing for each message level and specify the mail destination, the mail
contents, and the file to be started. For details, refer to “Event Link” in Chapter
3 of Section A in the “NEC Storage Manager User’s Manual”.
