Select hardware components according to the business conditions, requirements, disk capacity, and so

forth. Figure 1-1 shows an example of hardware configuration.

Business Server (Operated primarily)

• To utilize the data replication function most efficiently, it is better to separate business servers,

which process tasks, from backup servers. Thus, tape backup operation gives no additional load

to business servers.

• When doing disk backup instead of tape backup, no backup servers are required.

• Though the business or backup server may also be used as a management server, using a specific

management server is recommended. To avoid conflicts with host accesses, use of LAN

connection is strongly recommended for connection with disk array.

• The disk array accepts any tape drives. Select one of drives authorized by the backup software to

be used.

• Connect the path of individual servers, to be connected to the disk array, to the port of different

directors of the disk array, limiting the servers to be accessed by AccessControl.

• In the configuration example, the business servers are installed in a cluster and mutually connected

through the LAN specific to interconnection.

• Using data replication in the 4000 series or 3000 series requires a separate replication director.

same version.

(3) ReplicationControl Software Uninstallation

To uninstall ReplicationControl, follow the procedure below.

(1) Log on as the Administrator.

(2) Check whether the Storage Manager Volume List or ReplicationControl command is running and

whether the Volume List Display screen is open.

Terminate any running command and close any screen.

(3) Close [Event Viewer] if it is open.

6

Chapter 1 Installation Procedure

(4) Select the deletion of the following software component by using [Add/Remove Programs] ([Add

or Remove Programs] for Windows Server 2003) in [Control Panel] to start uninstallation:

• ReplicationControl

(5) Follow the directions of the uninstaller.

The following software components are uninstalled:

• ReplicationControl

• Storage Manager Volume List

If the Storage Manager Volume List or ReplicationControl command is running or the Volume List

Display screen is open, and uninstallation is performed, a message may appear which prompts you to

reboot the operating system. In this case, be sure to reboot the operating system.

(4) ReplicationControl Software Update

To update the ReplicationControl software, uninstall the existing software, and then install the new

software.

(5) Replication operation option setting

You can set various types of operations when executing a command by using the replication operation

option setting file (iSMrpl.ini).

For details of the replication operation option setting file, refer to the “Data Replication Command

Reference”.

7

Chapter 1 Installation Procedure

ReplicationControl outputs the operation trace (trace log) in the folder iSMrpl\etc\trace under the

folder where ReplicationControl has been installed (\Program Files\NEC\iSMrpl\etc\trace\ by

default) to deal with faults if occur.

In operation trace files, messages output to the standard output, standard error output, event log, and

command trace and the detailed internal information are recorded. These files are used as important

data for analyzing a fault if occurs. For details of information to be collected in the event of a fault,

refer to 2.2.7 “Information Gathering in the Event of a Fault”.

The amount of the output operation trace (file size) and retention amount and period vary depending

on the command execution frequency and other factors. You can set these items optionally by

writing the following option parameters:

[TRACELOG] section

RPLLOGFILENUM

Specifies the maximum number of log files to be saved.

When this option parameter is omitted, up to 10 log files are used sequentially.

RPLLOGFILEMAXSIZE

Specifies the maximum size per a log file to be saved in kilobytes.

When this option parameter is omitted, the size of one log file is about 400 kilobytes.

In ReplicationControl Ver2.1 or earlier, log data recorded during the number of days specified by

option parameter RPLLOG was saved in one log file. This conventional method is not

recommended due to the following reasons:

• The saved log file becomes larger in proportion to the command execution frequency.

• When the first command is executed after change-of-day, one day’s log out of the retention

period is deleted. Therefore, if one day’s log data to be deleted is large, it takes time to

delete it.

Accordingly, if option parameter RPLLOG has been used, it is advisable to change the setting to that

using the above option parameters RPLLOGFILENUM and RPLLOGFILEMAXSIZE for operation.

According to the disk capacity necessary for business or operation conditions, determine the logical

disk (LD) and hot spare configurations. For the 4000 series and the 3000 series, disk array

configurations are executed by maintenance personnel and therefore should be determined before

installation. To improve the access performance and keep tolerance against physical disk (PD) faults,

assign MV and RV to different ranks. MV and RV to be paired should have the same LD capacity.

If LD configuration is changed after starting the server, be sure to execute the create/display Volume

List command (iSMvollist -cr) after changing the configuration.

Figure 1-3 shows an example of setting five pairs.

• One LD is associated with one RANK. (The whole area for one RANK is assigned to one LD.)

• LD00 and LD05 are in RAID5 (4+P) configuration.

• LD01 to LD04 and LD06 to LD09 are in RAID1 configuration.

• Each DE has two spare disks.

• LD00 to LD04 are used for MV and LD05 to LD09 are for RV.

* This configuration is just an example. Actual configuration should be determined based on your

business conditions.

• The PD group number for PD and RANK is 00.

• For LD00 to LD09, one LD is associated with one RANK (the whole area for one RANK is assigned

to one LD).

• LD00 and LD05 are in RAID5 (4+P) configuration.

• LD01 to LD04 and LD06 to LD09 are in RAID1 configuration.

• LD00 to LD04 are used for the MV and LD05 to LD09 are for the RV.

• For LD0a, only one small-capacity LD is built with a RANK in RAID0 configuration.

• LD0a is used for an IV as the control volume.

* This configuration is an example. Actual configuration should be determined based on your

business conditions.

For the disk arrays with pool, you can build a small-capacity logical disk for a control volume. For

details of how to build a control volume, refer to descriptions about building logical disks in the

You can assign identification names to hardware components managed by the iSM. Identification

names can be given to the following items:

• Disk array subsystem name

• Logical disk name (plus OS type)

• Port name

A disk array subsystem name, logical disk name, and port name may be set without special restrictions,

except character types and character length; however, it is better to set these names considering the

operating conditions and server connection conditions. Determine the OS type according to the

servers connected. They are set from the iSM client. If the LD configuration is changed after

starting the servers, separate all pairs on all servers connected to the LD whose configuration is changed,

and, after changing the configuration, be sure to execute the Volume List create/display command

(iSMvollist -cr).

Normally, in a system without clusters, one volume cannot be connected to more than one server to

prevent data inconsistency due to file update from servers.

To prevent erroneous updates to this volume or erroneous changes to disk configuration on the business

servers, the RV must be separated using Access Control, etc. from the business server that uses the MV.

Furthermore, the MV must be separated from the business server that uses the RV, in the same way.

To prevent errors in control volume operation, the control volume must be connected only to a specific

server by using Access Control etc., so that it is not operated or updated from another server.

Before introducing servers, you must determine the server connection modes and design Access Control

settings. Access Control can be set for individual Ports or WWNs. Setting for Access Control

requires purchasing the AccessControl.

Figure 1-5 shows an example of Access Control setting for individual Ports.

To use the DynamicDataReplication or the RemoteDataReplication, you must unlock the product

license set in the disk array. To unlock the license, you must purchase the corresponding products for

the capacity category equal to or greater than the total physical capacity of the disk array.

When the replication management is executed by starting up the ReplicationControl, these products

check the licenses of the products purchased whether they are purchased properly.

If the total capacity of the physical disk exceeds the product’s specified capacity because physical disks

are added to the disk array system, no additional pairs can be set or canceled (however, replication

operations for the preset pairs are enabled).

• An RV of a maximum of four volumes can be set for one PV.

For DynamicDataReplication, an RV of a maximum of three volumes can be set at a time, however.

• An RV can be allocated to a maximum of two disk arrays for one PV.

• The DynamicDataReplication can be set in only one layer in the disk array.

• You cannot set dRV directly for dRV.

• Volumes with different volume capacities cannot be set as a pair.

• Unless the OS type is the same, the pair setting cannot be executed.

A control volume is used when a server issues control I/O to the relevant disk array. Select one of the

logical disks connected to each server for each disk array as the volume for issuing I/O to that disk

array and register the volume in the Volume List.

The use of a control volume has the following effects, in particular, in the backup server environment:

• Operation can also be continued even when an RV connected to the server or a link-volume (LV) for

the snapshot function cannot be accessed from the server (operating system) due to a data replication

or snapshot operation.

• From a server that is not connected to an MV to be operated, Replicate and Separate can be executed.

The logical disk which can be operated using the control volume from a server is a logical disk which

is allowed to access that server by the Access Control setting for the disk array or a logical disk

paired with a logical disk which is allowed to access that server.

For details of a control volume, refer to 3.9 “Control Volume” also.

For details of the Volume List Display function, refer to the help of the Volume List Display screen or

the “Data Replication User’s Manual (Function Guide)”.

A control volume is used when a server issues control I/O to the relevant disk array. You can select

one logical disk for each disk array as a control volume. Prepare a volume such as IV with which the

server can properly issue I/O to the disk array.

Do not select an RV or a link-volume (LV) for the snapshot function as a control volume because it

may enter the Not Ready state during operation.

Creation of Volume List is required before using replication operation command. A Volume List is

created by the iSMvollist command with an argument -cr. Execute iSMvollist command by a user that

belongs to Administrators group.

When you have already performed [Create/Update Volume List] using the Volume List Display

function (screen operation) according to the instructions described in 1.5, “Control Volume Setting”,

you do not have to perform the following operation.

iSMvollist -cr

Upon successful creation of Volume List, the following message appears:

iSM11701: Volume list is created successfully.

If creation of a Volume List fails, execution of replication operation command is disabled.

Troubleshoot in accordance with an error message or with operation error tracing, create a Volume List

again.

Even under operation with replication, a Volume List must be created again in the following cases.

Failing in updating of Volume List may result in data inconsistency upon execution of replication

operation command.

• Change of disk array settings (disk array name, logical disk name, format)

• Setting/Change of Access Control

• Adding/change/deleting of disk

• Adding/change/deleting of partition

• Adding/change/deleting of drive name on partition, and of drive path mounted on NTFS folder

To use a control volume, before creating or updating a Volume List, check the following:

• A control volume has been selected and registered in advance using the Define Control Volume

function from the Volume List Display screen.
