It is one function of iSM and a disk array configuration setting is NEC Storage series. It is used when
carrying out a configuration setup of a disk array at the time of initial installation and extension of the disk
array.
Disk array configuration setting is executed by four commands; iSMautobind, iSMconf, iSMview, and
iSMrepair
This software operates for the following disk arrays.
NEC Storage 1000 series all commands can be used.
NEC Storage 2000 series all commands can be used.
NEC Storage 3000 series only configuration display command can be used (Configuration setting
should be executed by a maintenance personnel).
NEC Storage 4000 series only configuration display command can be used (Configuration setting
should be executed by a maintenance personnel).
For the iSMview command, refer to the description part about iSMview in the “NEC Storage Manager
User’s Manual” in accordance with your OS.

iSMautobind is a command mainly used in initial introduction of the disk array, and it configures RANK,
LD and Hot-spare necessary for the operation at a time. Command Line Interface (CLI) is used as user
interface, with which necessary items are interactively typed from the command line, according to the
displayed menu.
* Note that the execution of batch setting command deletes all logical volumes that exists before the
execution, and those volumes cannot be restored.

- In HP-UX, execute all commands by super user or NEC Storage Manager administrator.
* About registration and deletion of NEC Storage Manager administrator, refer to the description part
about the NEC Storage Manager administrator setting command in the “NEC Storage Manager User’s
Manual (UNIX)”.
- In Solaris system, execution of all commands must be allowed for a super user only.
- In Windows 2000, execute all commands by the authority of Administrator group.

Chapter 2 Storage Overview
This chapter explains the overview of NEC Storage series disk array, which is the object of the iSM management.
iSM is software that provides the operation and a variety of information (configuration, status, etc.) of the NEC
Storage series disk array. Therefore, to understand the iSM functions and to use the iSM efficiently, knowledge
of disk array is required. The outline of disk array necessary to use for iSM is explained in the following
sections.

The outline of the NEC Storage series disk array which is the object of the iSM management is
explained below.
(1) NEC Storage 4000 series
NEC Storage 4000 Series, high-end disk array of NEC Storage Series, realizes high scalability
(up to 10 extended cabinets can be connected to a basic cabinet and up to 1200 PDs can be
mounted) and high availability (all components have redundancy) and displays stable
performance.Furthermore, it provides the function to replicate logical disks
(DynamicDataReplication and RemoteDataReplication) in and between disk arrays, which
enables backup and batch processing to be performed in parallel with the main function.
(2) NEC Storage 3000 series
NEC Storage 3000 Series, mid-range disk array that can handle key business of NEC Storage
Series, realizes high scalability (up to 2 extended cabinets can be connected to a basic cabinet and
up to 240 PDs can be mounted) and high availability (all components have redundancy) and
displays stable performance. Furthermore, it supports functions equivalent to all of the
solutions (DynamicDataReplication, RemoteDataReplication, etc.) provided by NEC Storage
4000 Series, the high-end disk array, thereby efficiently performing business.
(3) NEC Storage 2000 series
NEC Storage 2000 Series, mid-range disk array of NEC Storage Series, realizes high scalability
(up to 14 disk enclosures can be extended) and high availability (main components have
redundancy). Furthermore, it provides a function to replicate logical disks
(DynamicDataReplication) in the disk array, which enables effective backup and batch
processing.

(4) NEC Storage 1000 series
NEC Storage 1000 series, entry model disk array of NEC Storage series, realizes the little space
consuming (One controller and maximum of 15 PDs may be loaded to 3U) and high availability
(main components are redundant).

(1) Components
The NEC Storage series disk array is composed of Disk Array Controller (DAC), which carries
the component of control systems, such as host director, disk director and cache, and disk
enclosure (DE) that carries two or more Physical Disks controlled by DAC.

<Components identification>
In the NEC Storage 4000/3000 series disk array, the cabinet composed of Disk Array controller and two
or more disk enclosures is called as “Basic Cabinet (BC)” and the cabinet that is composed of plural
disk enclosures to be connected to basic cabinet is called as “Extended Cabinet (EC)”. NEC Storage
4000/3000 series can mount 10 or 15 Physical Disks (PDs) per disk enclosure, and 4 disk enclosures are
managed as 1 group (array group). Individual PD has identification number per PD management
group (PD group) that includes the above 4 array groups. Thus the combination of PD group number
and PD position number enables identifying of the physical mounting place of the PDs.
In the same way, unique identification number is assigned to other components in disk enclosure
(shown below), per controller unit, and this identification number enables components in the same disk
enclosure to be specified. But assignment of identification number depends on number of component in
disk enclosure.
NEC Storage 2000 series is also composed of DAC and one or more disk enclosures. (There is no
concept of basic cabinet and extended cabinet in NEC Storage 4000 series). It can mount 10 or 15
Physical Disks (PDs) per disk enclosure. PD management group (PD group) is defined depending on
the connection relation to disk array controller. (PDs connected to the same group are defined as one
PD group). There is no concept of array group.
In the NEC Storage 1000 series disk array, DAC and DE which are in different cabinets in NEC
Storage 2000 series are put in the same cabinet. 15 Physical Disks (PD: Physical Disk) can be carried in
DAC part. Because there is not the concept of array group, the Physical Disks connected to the same
loop are managed as one group (PD group).
