connection are automatically detected and monitored.

(ii) [Disk Array Subsystem List]

[Disk Array Subsystem List] displays the disk array information currently registered.

(When a disk array specified by the disk number is selected, the column heading [IP Address or Host Name] in

the figure above appears as [Disk].) Up to 32 disk arrays can be registered in the [Disk Array Subsystem List].

(iii) [Add] button

To add a disk array, use the [Add] button to open the Add screen.

(vii) [Specification by Disk Number]

To monitor a disk array in FC connection, select [Specification by Disk Number] to display the disk addition

screen (Figure 1-5). Disk number is a number assigned by Windows to manage logical disks. The setting is

generally not required since the disk arrays connected by FC are automatically detected by checking [Automatic

detection of Disk Array Subsystems connected by FC].

Figure 1-4 Disk Array Subsystem - Add Screen - 2

(viii) [Main IP Address]

In [Main IP Address], specify an IP address or host name. Up to 63 characters can be used for a host name.

Non-ASCII code characters, control characters, double quotation mark, and space cannot be used for a host

name.

iSM connects to the IP address or that specified for the host name (port number: 2730) to conduct monitoring.

I-7

Chapter 1 Server Installation

(ix) [Sub IP Address]

In [Sub IP Address], up to two IP addresses can be specified for the disk arrays with two SVPs.

iSM connects to the IP address or that specified for the host name (port number: 2730) to conduct monitoring.

(x)

Figure 1-5 Disk Array Subsystem - Add Screen - 3

(x) Disk Number Entry field

In an entry field on the screen as shown in the figure above, specify a disk number. A value from 0 to 9999

can be specified for a disk number. Check the disk number of the disk array to be monitored, using the

Volume List (iSMvollist -dl) command in advance. For details, refer to 5.3 “Volume List Command

(iSMvollist)”.

1. Without any disk number being specified, disk arrays can be monitored via FC by specifying [Automatic

detection of Disk Array Subsystems connected by FC].

Specification of a disk number is not recommended because the disk number may change when the OS is

rebooted or an FC fault occurs.

2. For Windows Server 2003, disks in disk arrays may not be accessed when, for example, the access control

setting is changed. Therefore, it is strongly recommended that disk arrays be monitored through TCP/IP

connection when iSM server is installed and used under Windows Server 2003.

User information is set in the following screen. iSM server uses user information as an account. iSM server uses

this information in order to identify the user who connects by iSM client. This information is composed of user

names, passwords, and user levels (refer to explanation of the “User-Add” screen given later for details). As a

default, a user is registered having the user name of iSM, password of iSM and user level of L1 (only reference to the

information is allowed). Add, as required, users of the user level L3 who can change configuration of disk arrays.

For the iSM client, refer to 5.2 “Client Start/Stop”.

Set user information on the Setting Utility screen shown below.

To start the Setting Utility screen, select [Start] → [Programs] ([All Programs] for Windows Server 2003) → [Storage

Manager Server] → [Setting Utility], or select [Server Menu] → [Setting Utility]. If having changed the

environment setting, restart the iSM server. Information set on each screen is saved by clicking the [OK] button.

Setting of one or more pieces of user information is required. Note that user information of iSM set on this screen

is independent of the OS user or password.

password cannot consist of all spaces.

(vii) [User Level]

In [User Level], specify the operation authorization level of the user. iSM defines the three kinds of user

levels that set/refer information of disk arrays by iSM client. An upper level (L3>L2>L1) allows all

operations of a lower level.

L1(Level 1): Only reference to state display is authorized.

L2(Level 2): Operations at the level of the replication, performance monitoring, performance optimization, and

snapshot functions are authorized.

L3(Level 3): All operations are authorized, such as changing the disk array configuration.

• In [File Transfer Information], specify information regarding the file transfer function.

To transfer files between the iSM server and iSM client, the iSM internally uses the FTP through the following

operations of the iSM client.

Therefore, the FTP site environment (installation of IIS FTP Publishing Service and building of the FTP site) must

be built on the iSM server node before the iSM server is operated.

y Selecting [Get Configuration Setting Info.] on the configuration setting screen

y Selecting [Download Statistic Information files] on the performance screen

y Selecting [Busy Ratio Graph] and [Replacement Effect Prediction] on the performance optimization screen

y Selecting [Difficulty Information Gather] on the main screen (iSM client)

When these functions are not used, settings for file transfer are unnecessary.

(ix) FTP User Name

Specify the name of an FTP user who is to make FTP connection from the iSM client to the iSM server node.

You can specify only an FTP user who is permitted to use the FTP and authorized to read from and write to the

folder specified for [Temporary Folder].

The default user name is iSMuser. The FTP user name can be specified with up to 32 bytes.

I-20

Chapter 1 Server Installation

(x) FTP Password

Specify the password of the user specified for [FTP User Name].

If using “anonymous” or “ftp” as the FTP user, specify the mail address. The FTP user password can be

specified with up to 58 bytes.

(xi) FTP Password Confirmation

For confirmation, enter the same value as for [FTP Password].

(xii) IP Address of FTP Site

Specify the IP address to be used as the FTP connection destination from the iSM client. If the IP address of

the FTP site is not specified, the system automatically gets the IP address of the iSM server node and uses it as

the FTP connection destination.

Set a suitable IP address in the following cases:

y An IP address is explicitly written in the specification of the IP address of the FTP site.

(Select [Properties] of the FTP site used by iSM → [FTP Site] → [Identification] → [IP Address], in which an

IP address has been specified.)

y The iSM server is used in cluster environment.

In particular, to operate the FTP service in cluster environment, place the iSM server and the FTP service in

the same failover group, and specify a floating (virtual) IP address. To operate the FTP service starting as a

service in cluster environment, specify the real IP address.

* Do not specify “127.0.0.1”, “0.0.0.0”, or “255.255.255.255” as an IP address.

(xiii) Port Number of FTP Site

Specify the port number of the FTP site to be used by iSM.

Select [Properties] of the FTP site used by iSM → [FTP Site] → [Identification] → [TCP Port], in which a port

number has been specified. The port number must be specified here. The default port number is 21.

(xiv) FTP Root Folder

Specify the root folder of the FTP site to be used by iSM.

Select [Properties] of the FTP site used by iSM → [Home Directory] → [FTP Site Directory] → [Local Path],

in which a path has been specified. The path must be specified here. The default root folder is the drive in

which the iSM server is installed. The root folder can be specified with up to 192 bytes.

* If not specifying a virtual directory path:

Select [Properties] of the FTP site used by iSM → [Home Directory] → [FTP Site Directory], in which check

permission for both read and write.

(xv) Temporary Folder

Specify the folder (the local directory of the computer on which the iSM server operates) that is to be used as a

temporary folder when the iSM uses the FTP. If a network resource or network directory is specified, the file

transfer function may not operate correctly.

This folder (drive) needs a free space of 300MB × the number of files concurrently transferred or more. If the

drive containing the iSM server does not have a free space large enough, specify the folder of a drive having a

free space large enough.

If not using the default folder, give the group administrators “Full Control” access authority to the specified

folder and the high-level folders.

Also authorize the user specified for [FTP User Name] to read from and write to the folder specified here.

The default folder is “installation destination folder\etc\temp”. The folder can be specified with up to 192

bytes.

I-21

Chapter 1 Server Installation

* In particular, to operate the FTP service under cluster control in cluster environment, you should place the

iSM server and the FTP service in the same fail over group on the local disk.

(xvi) Virtual Directory Path

If using a virtual directory, specify the path for the user, specified for [FTP User Name], to access [Temporary

Folder] through the FTP. The path can be specified with up to 192 bytes.

If [FTP Root Folder] is at a higher level than [Temporary Folder] (or if the folders are identical), [Virtual

Directory Path] need not be specified. The following shows examples:

Example 1: FTP Root Folder: C:\

Temporary Folder: C:\Program Files\NEC\iSMsvr\etc\temp

In this case, the temporary folder can be accessed through the path “/Program

Files/NEC/iSMsvr/etc/temp” in the FTP. Thus, a virtual directory path need not be specified.

Example 2: FTP Root Folder: C:\Program Files\NEC\iSMsvr\etc\temp

Temporary Folder: C:\Program Files\NEC\iSMsvr\etc\temp

In this case, the temporary folder can be accessed through the path “/” that is to the temporary

folder. Thus, a virtual directory path need not be specified.

In other cases, a virtual directory needs to be created and a virtual directory path needs to be specified. The

following shows examples:

Example 3: FTP Root Folder: C:\InetPub\FTPRoot

Temporary Folder: C:\Program Files\NEC\iSMsvr\etc\temp

If a virtual directory is created under the conditions below, specify “/iSMftp” for [Virtual

Directory Path]. In this case, the temporary folder is accessed through the path “/iSMftp” in the

FTP.

Alias: “iSMftp”

Path: “C:\Program Files\NEC\iSMsvr\etc\temp”

Example 4: FTP Root Folder: C:\InetPub\FTPRoot

Temporary Folder: D:\iSM\temp

If a virtual directory is created under the conditions below, specify “/iSMftp2” for [Virtual

Directory Path]. In this case, the temporary folder is accessed through the path “/iSMftp2” in the

FTP.

Alias: “iSMftp2”

Path: “D:\iSM\temp”

Example 5: FTP Root Folder: C:\InetPub\FTPRoot

Temporary Folder: D:\iSM\temp

If a virtual directory is created under the conditions below, specify “/iSMftp3/temp” for [Virtual

Directory Path]. In this case, the temporary folder is accessed through the path “/iSMftp3/temp”

in the FTP.

Alias: “iSMftp3”

Path: “D:\iSM”

* For the path to be specified in creating a virtual directory, be sure to specify the local directory of the

computer on which the iSM server operates. If a network resource or network drive (or a directory under the

drive) is specified, the file transfer function may not operate correctly.

* If specifying a virtual directory path (using a virtual directory), give access permission for both read and write

during creation of the virtual directory.

I-22

Chapter 1 Server Installation

The file transfer function of iSM is operated with FTP. An FTP command of Windows is used on the iSM client

side and an FTP server of each OS is used on the iSM server. In this case, only active mode (PORT mode) is used

as FTP data transfer function. Therefore, if there is a firewall or NAT in the network between the iSM client and

the iSM server, the file transfer function may not be available.

Before attempting to operate iSM, be sure to connect the FTP (and perform get and put processing) through the

command prompt on the computer on which the iSM client operates, and confirm that the items in [File Transfer

Information] are set correctly.

• In [Replication Information], specify information regarding the replication function.

(xvii) Monitor of State Changes

Determine whether to monitor the transition of the replication states.

Monitor: The replication state transition is monitored.

Don’t Monitor: The replication state transition is not monitored.

(xviii) Port Number

Specify the number of the port to be used when the ReplicationControl command is issued via iSM. A value

from 1 to 65535 can be specified. The default value is 8030.

• In [Snapshot Information], specify information regarding the snapshot function.

(xix) Port Number

Specify the port number to be used when the SnapControl command is issued via iSM. A value from 1 to

65535 can be specified. The default value is 8040.

To uninstall the iSM client, follow the procedure below.

(1) Log on as the Administrator.

(2) Remove “Storage Manager Client” by using [Add/Remove Programs] ([Add or Remove Programs] for Windows

XP/Windows Server 2003) in [Control Panel]. Because setting information etc. is not deleted, reinstallation is

easy.

Uninstalling the iSM client deletes all of the icons on the desktop and the menu items. If you are to re-install the

iSM client after uninstalling it, copy the icon on the desktop to an appropriate folder before uninstalling it.

After re-installing it, copy the saved icon to the following folder on the system drive.

<Desktop icon>

\Documents and Settings\All Users\Desktop

<[Start] menu icon> * When the default value is the program folder

\Documents and Settings\All Users\Start Menu\Program\iSM Client

To restore the icon to the state where uninstallation was not made, copy it to the folder above.

Re-install the iSM client in the folder from which the client was uninstalled. Otherwise, the icon reference will be

nullified.

In general, connecting the iSM client to the other version of iSM server is not allowed. (The value of x.y. of x.y.z. of

a version is compared here. z should be disregarded.)

However, during operations while waiting for subsystem and in other temporarily unavoidable circumstances, use it

temporarily in an environment where the version of the iSM client is newer than the version (V1.5 or later) of iSM

server. The functions which can be used are limited to the functional range of the version of the iSM server at this

time.

Chapter 3 Basic Functions

Chapter 3 explains the function that can be used when the iSM is introduced. The basic function provides the following function

necessary for disk array operations such as the display function of physical disk configuration in the disk array and logical disk

configuration that can be recognized from the business server.

• Configuration display: A function that displays the configuration information of physical and logical components (resources)

that configure the disk array.

• Status monitoring: A function that displays the status of components (resources) that configure the disk array.

• Configuration setting: A function that configures the disk array and implements logical components.

• Fault monitoring: A function that informs the fault information in the disk array in real time.

• Log output: A function that outputs the fault information and the operating information as the operation history for

system log file and exclusive log file.

• Event link: A function that executes the action on the notice to the operator and server upon the occurrence of

operating information and fault information.

The basic function is composed of the above-mentioned 6 functions, and the efficient operation of disk array is possible by using

these functions. The detail functions are described in the following section.

These icons are monitoring state where all disk array components are in normal
status. The icon’s shape differs by disk array type.

This icon is a monitoring state where an event or fault (except critical fault)
that needs “maintenance” occurred in any disk array components. (Note 1
and 2)

This icon is a monitoring state where a critical fault occurred in any disk
array components. (Note 2)

This icon is a monitoring state where “threshold excess” occurred in any pool
for snapshot. (Note 3)

These icons show that the disk array is in monitoring stop status or under
configuration setting. The icon’s shape differs by disk array type.

This shows monitoring stop status or under configuration setting.
If this icon is displayed, an event or fault (except critical fault) that needs

“maintenance” occurred in any disk array components just before stopping
monitoring.

This shows monitoring stop status or under configuration setting.
If displaying this icon, a critical fault has occurred in any disk array

components just before stopping monitoring.

This shows monitoring stop status or under configuration setting.

Note 1 If an event or fault (except critical fault) that needs “maintenance” occurred, the disk array icon can be

switched between “ ” and “ ”. Switching is executed at [Display Maintenance State] in

environment setting dialog by selecting [File] → [Environment Settings] from the menu. Refer to 5.2

“Client Start/Stop” for details.

Note 2 Although a component fault is displayed by “ ”, whether this icon deserves the critical fault or not is

decided at a higher layer, and the icon according to the status is displayed. Please refer to 3.2.2

“Description of screen and operation” about the component status icon and display in higher layer.

Note 3 If a threshold excess occurred in pool for snapshot, the icon “ ” is displayed. If, however, the

integrated operating state of a disk array component is faulty or an event or fault (except critical fault)

that needs “maintenance” occurred, the icon displays the integrated operating state. For details on

actions to be taken when a threshold excess occurred, refer to the “Snapshot User's Manual (Function

Guide)” (IS030).

Note 4 The shade of icon indicates the monitoring state of target disk array. If icon is gray, the monitoring of

target disk array stops.

If displaying this icon, “threshold excess” has occurred in any pool for
snapshot just before stopping monitoring.

This icon indicates that disk array components are not being monitored.
If this icon is displayed, the SVP settings of the target disk array include an

incorrect IP address setting, or the target disk array could not be connected to
the iSM server.

The state monitoring function monitors the generation of the following events in the disk array which is an object of

iSM.

<Event>

• Generation of status transition in the components

• Existence of change of a disk array name, a logical disk name and a port name

• Generation of configuration change

• Occurrence of a threshold excess of the quantity used of snapshot

iSM supports the polling mode to acquire the monitoring information in the fixed interval. When the above event is

detected, iSM not only reflects the detected event on the configuration control screen of an iSM client but also outputs

the message to various logs (event log, operation log). Besides, it can perform link processing such as maintenance, as

started by the event detection. For log output and link function, refer to sections 3.5 “Log Output” and 3.6 “Event

Link” in this manual.

The message indicates that the disk array (whose name is “Storage4100/07” and serial number is

“3000000000000003”) has been renamed “Storage4100/dwh1”.

For details, refer to the “Messages Handbook”.

(b) State Value Reflection

Due to the detection of status transition, name change, or configuration change, respective status of changed

elements is shown in the configuration display area on iSM client.

When events such as fault, caution, and offline occur in each component, status value of the object element

for individual element layer is changed and the corresponding icons are also changed. Status of element

layer or disk array layer change depends on the status change of individual element layer. For example, if

attention event occurs in PD, PD of the upper element layer and disk array layer change to normal status

(maintenance). (Table 3-12)

Furthermore, when two types of event at different fault level simultaneously occur in the individual element

layer, an event with higher fault level is always reflected on the upper layer.

For contents of display, refer to 3.1 “Configuration Display” in this manual.

Nickname setting function is used via iSM client to set disk array name, logical disk name (and disk OS Type), and

port name for the disk array which is the object of iSM monitoring. By setting these names so that they match to the

identification information of the individual daily work processing systems that use the disk arrays, efficient control of

the disk array can be achieved. Once information is set, it can be acquired regardless of iSM rebooting because the

preset name is recorded inside the disk array.

II-50

Chapter 3 Basic Functions

* Other Errors *

When “Setting Failed (nn)” is displayed for setting process of disk array name, it is considered that the errors

are detected after completion of I/O for disk array. Check by the browser whether the disk array setting has

been executed, and set again if necessary.

(2) Disk Array Setting Condition and Naming Rule

(a) Setting Condition

Disk array name should be set under the following conditions. (Settings other than the followings are treated as

parameter errors.)

• 1-byte alphanumeric characters including uppercase and lowercase characters. (When configuring a name with

plural information, “/”or “_” can be input)

• Maximum number of characters: 32.

(b) Naming Rule

A disk array used from the ACOS-4 system must have its name identified by the ACOS host, especially when

DynamicDataReplication or RemoteDataReplication are used. Therefore, to determine the disk array where the

object logical disk exists, an identification name for the disk array should be set. Make a disk array name in

combination of alphanumeric characters including uppercase characters and “_” (under bar), within 32 bytes.

Definition Example: CABINET01,CABINET02

In addition, when operating a disk array through other systems, it is recommended to set a disk array name that

matches with identification information from the system, along with logical disk name and port name.

In addition, when disk array name is not set, “16 characters peculiar to a disk array” is set as default value at the

time of shipment.

(3) OS type/logical disk name setting

OS type/logical disk name is set using the following procedure.

(a) Select (left-click on) the logical disk (for which you want to set an OS type and name) in the configuration

information display area (or the information list display area), right-click on it, and select [Settings] (or

[Operation] on the menu bar → [Logical Disk Name Settings]). The Setup of Logical Disk OS Type/Name

dialog box (Figure 3-26) appears.

(b) In [New OS Type] or [New Name] Edit Box, input a logical disk name following the rules defined in (4) “OS

Type/Logical Disk Name Setting Conditions and Naming Rules” and click [OK] button.

(c) As a result of the setting, the following information is displayed in the dialog.

“Setting has been completed” Execution result is normal.

“Setting information (OS Type/Name) is incorrect” Parameter Error

“Same name exits” Same name exits.

“Error occurred in the access to the Disk Array
Subsystem”

“As for Logical Disk with replication setting, OS Type
cannot be changed”

“Cannot execute the demand during the suspension of the
object Disk Array Subsystem monitoring”

“Cannot execute the demand during the configuration
setting”

“Demanded process has already been executed” Already executed

“Failed in setting (nn)” Other errors (nn is a decimal detail code.)

Table 3-14 Execution Result Dialog

Message State

Access error occurred.

OS Type of logical disk whose replication pair is set
is changed.

Setting is unavailable due to monitoring stop.

Setting is unavailable due to under configuration
setting.

* Other Errors *

When “Setting Failed (nnh)” is displayed for setting process of logical disk name, it is considered that the errors

are detected after completion of I/O for disk array. Check by the browser whether the disk array setting has been

executed, and set again if necessary.

(4) OS Type/Logical Disk Name Setting Conditions and Naming Rules

(a) OS Type setting conditions

Select an OS Type from the Table 3-15 below according to a system to operate a logical disk.

Especially, you must set a correct OS type when using DynamicDataReplication or RemoteDataReplication in

the following systems:

• Logical volume used in ACOS-4 system

• Logical volume used in ACOS-2 system

• Logical volume used in Windows system

Table 3-15 OS Type List

OS Type Description

A2 Logical disk operated by the ACOS-2 system

A4 Logical disk operated by the ACOS-4 system

(For instructions on setting this type, contact the maintenance
engineer.)

AX Logical disk operated by the AIX system

CX Logical disk operated by the Solaris system

LX Logical disk operated by the Linux system

NX Logical disk operated by the HP-UX system

WN Logical disk operated by the Windows system

For instructions on setting the ACOS-4 type, also refer to Appendix in the “Configuration Setting Tool User’s

Manual (GUI)”.

Chapter 3 Basic Functions

If the logical disk to be set is a snapshot related volume (of which snapshot type is BV, SV, LV, SV*, or SDV), the

OS type cannot be changed.

The [New OS Type] edit box is grayed.

(b) Setting Conditions

A logical disk name should be set according to the conditions below. (Settings other than those listed below are

processed as parameter errors.)

• 1-byte alphanumeric characters including upper- and lowercase characters. (When configuring a name with

plural information, “/”or “_” can be input)

• Maximum number of characters: 24

(c) Naming Rules

A logical disk used by the ACOS-4 system must have its logical disk name that can be identified by the ACOS

host, especially when DynamicDataReplication or RemoteDataReplication are used. Therefore a logical name

should be set according to the rules below.

Logical disk name = [/system name/] + device identification name

System name: Generic system name. An identifier is composed of the combination of

uppercase alphanumeric characters and “_” (under bar) within 18 bytes.

It may be omitted.

Device Identifier: Name of device defined in ACOS-4 system

Example of definition: MS01,/SYSTEM01/MS01

Moreover, when operating a logical disk by other systems, it is recommended to set a logical disk name that

matches with identification information of the system, along with disk array name and port name.

In addition, when OS type and logical disk name are not set, blank for the OS Type, “the 16 characters peculiar to

disk array + 4 characters of logical disk number” for the logical disk name are set as default value at the time of

shipment.

(5) Port name setting

Port name should be set according to the procedures below.

(i) Select (left-click on) the disk array system having the port (for which you want to set a name) in the

configuration information display area (or the information list display area), right-click on it, and select [Settings]

(or [Operation] on the menu bar → [Disk Array Subsystem Name Settings]). The Disk Array Subsystem Name/

Port Name Setting dialog box (Figure 3-25) appears.

(ii) Select a port number (port name) from the [Port Number] list and input port name in the [New Port Name] edit

box, following the rules defined in (6) “Port Name Setting Conditions and Naming Rules” and click [Apply]

button.

II-53

Chapter 3 Basic Functions

(iii) As a result of the setting, the following information is displayed in the dialog.

“Setting has been completed” Execution result is in normal

“Setting information is incorrect” Parameter Error

“Same name exists” Same name exists

“Error occurred in the access to the Disk Array
Subsystem”

“Cannot execute the demand during the suspension
of the object Disk Array Subsystem monitoring”

“Cannot execute the demand during configuration
setting”

“Demanded process has already been executed” Already executed.

“Setting failed (nn)” Other errors (nn is a decimal Detail Code.)

*Other Errors*

When “Setting Failed (nnh)” is displayed for setting process of logical disk name, it is considered that

the errors are detected after completion of I/O for disk array. Check by the browser whether the disk

array setting has been executed, and set again if necessary.

Table 3-16 Execution Result Dialog

Message State

Access error occurred.

Setting is unavailable due to monitoring stop

Setting is unavailable due to under
configuration setting

(6) Port Name Setting Conditions and Naming Rules

(a) Setting conditions

Port name should be set with the following conditions. (Settings other than those listed below are processed as

parameter error.)

• 1-byte alphanumeric characters including upper- and lowercase characters. (When configure a name with plural

information, “/”or “_” can be input)

• Maximum number of characters: 32

(b) Naming rules

As well as the disk array name and the logical disk name, it is recommended to set a port name that matches with

the identification information for the system being operated.

In addition, when port name is not set, “16 characters peculiar to disk array + 2 characters of director number + 2

characters of port number” for the port name is set as default value at the time of shipment.

You can set a name to a port only for a host. In the [Disk Array Subsystem Name/Port Name Setting] dialog box,

only the number of the port for a host is displayed.

The same contents with operation log are displayed in the message display area by the fault monitoring function. The

display shows clearly the importance of the messages by adding an icon of each message level at the start of the

message. The message which has already been displayed once also extracts to individual log file on the PC side.

Whatever display status iSM client may be on screen according to the message level, it has function for noticing the

fault occurrence to the user.

(1) Output to the message display area

The same operation log that is extracted on the iSM server side is displayed in the message display area.

However, it displays only what is outputted during iSM client connection.

The message which shows connection/disconnection between iSM client and server is also displayed as an

individual message. After determining the message level, add the proper icon (

(Notice, Info)) at the start of line.

(2) Log collection

The message which is displayed in the message display area is outputted in the individual log file on the PC side.

Up to 1MB data can be stored in one log file. If it exceeds 1MB, it is renamed to an iSM old file and a new iSM

log file is created. Because two files, OLDiSM.log and iSM.log are used one after the other, a maximum of 2MB

file can be saved and more capacity is not needed.

(3) User notification function

(Err) / (Warning) /

Because the iSM client is not always displayed in the foreground, there is a function which notifies faults to the

user at each message level.

When the message level is (Err) / (Warning), the task tray blinks and the notification button changes from

to .

Operation log is composed of an outputting log file, its generation file (backup file) and a generation management file

saving the management information of generation file. An operation log is created on the log file saving directory

(installation directory\etc\log). A generation file has a structure that holds backup of a log file one by one and it is

created to a maximum of 99 files. However, if the number of generation files exceeds the maximum, the oldest file will

be overwritten.

These file changes and name changes are performed automatically, and the user does not need to pay attention.

Example: When 17 generation files have been created by the operation log.

Chapter 3 Basic Functions

(1) Log file

One message output by iSM server is saved as one record into the outputting log file. When the log file exceeds

the specified size, it is initialized after copying to a generation file.

File size: 1 to 10 (MB) Default is 1MB; can be specified by environment setting.

File name: “iSM_Log” + .log

(2) Generation file

A generation file is a backup file of the log file, and is created with maximum of 99 files. The generation file

shows the backed up order by the generation number in its file name, and the larger the number is, the newer the

file is. However, the file with the largest number is not necessarily the newest one because overwriting is made

from the file of the generation number 1 and subsequent files when the number of created files exceeds the

maximum. To identify the newest file correctly, refer to (3) “Generation management file”.

File name: “iSM_Log” + nn + .log

Generation number: 01 to 99

(3) Generation management file

A generation management file is a file that shows the latest information on the generation file numbers, and saves

the information with 2-digit generation number (2 bytes). When the generation number of generation

management file is 99, the next generation number will be assigned to 01. When a generation management file

does not exist right after the installation of iSM, or a number other than 01 to 99 is accidentally specified, the

following processing should be done.

(i) Set the generation number to “01” for the next file to be processed.

(ii) After backing up the information to a generation file, re-create the generation management file

File name: “iSM_Log” + .cnt

If the definition for the message level of a message that has arrived is registered with environment settings, the defined

actions are executed. As actions for message levels, starting a batch file or program take precedence over mail

transmission. If, during the execution of an action, the next message is received, the actions for the next message will

be executed after the actions to be executed for the message currently being handled are completed.

In batch file or program starting, full path of the temporary file that stored the message body (installation folder

\etc\msgdrv\nnnn.txt) is sent as the first parameter. For batch file, program, or programs that are started up by these

files, read the temporary file if necessary and receive the message.

For mails, mail header files are sent as mails to the defined SMTP server.

If the sending of mails to the SMTP server does not end within 30 seconds, the sending is interrupted due to a time-out

error. Timeout, SMTP error and starting failure of execution files or batch files are notified via message so that they

can be checked on the operation log.

Because multiple link operations cannot be performed at the same time, up to 30 messages generated during a link

operation will be stored in a buffer. If more messages are generated, the excess messages will be discarded.

A loop may be formed if an error event with the event link function arrives at the event link function again and,

therefore, the messages output by the event link function itself will not be subject to linking.

In addition, when starting a batch file through the event link function, “Administrator” must be set to the account of

“Storage Manager”.

(1) Header File

The header file is the form of the actual mail to transmit, and mainly describes the header part of the mail. Input

“FROM:” on the first line, and write the mail sender’s name. If mail transmission fails in SMTP server due to

wrong target mail address, etc., an error message from SMTP server may send to a sender’s mail address. The

contents of the mail text after the second line are sent as it is, the part above the blank line is the header, and

subsequent part is the body of the mail. A message including “$MSG” in body is converted into a message that is

output to an operation log triggered by “$MSG” for linkage.

FROM: [e-mail]

SUBJECT: iSMserver error report.

← blank line

This is the iSMserver at XXXX(domain name etc.)

Error Reporting.

$MSG → A message output to operation log that triggered object linkage is described in this line.

Describe sender’s mail address.

Chapter 3 Basic Functions

1. Mail address to input on the “FROM:” line must be a complete one that includes domain name.

2. Various header lines in accordance with RFC822 can be written in the header part.

3. Any contents can be described in the body part.

4. The size of the whole header file must be less than 1KB. Also, one line must be less than 256 bytes (including

blank / tab / carriage return).

5. When a part of “$MSG” of a certain line is replaced into the message content, the “$MSG” which appears first

can be replaced. So even if two or more “$MSG”s are described in one line, only the first “$MSG” is

replaced. However, if the “$MSG”s are described in each line, they are replaced by the same contents.

When an iSM server has been installed, reports to ESMPRO Manager are defined automatically if ESMPRO Agent is

installed in advance to the server to run. Likewise, when an iSM client is installed, the iSM client is registered

automatically to the operation window as an operation monitoring tool if ESMPRO Manager is installed in advance.

This enables ESMPRO to perform integrated monitoring including business servers and storage.

(1) Alert report to ESMPRO Manager

When an iSM server is installed on the server machine where ESMPRO Agent has been installed, the ESMPRO

report function is set to allow reporting a disk array fault or iSM fault to ESMPRO Manager.

When an iSM client is installed on the machine where ESMPRO Manager has been installed, an iSM client is

registered to the ESMPRO operation window as an operation monitoring tool. This enables ESMPRO to perform

integrated monitoring including business servers and storage.
