Items	Windows	Solaris	Linux
Transaction name	Required	Required	Required

Each item is explained below.

Transaction name
Name of cluster transaction.
Logical IP address
IP address for data communication with the Web Console and Managed Servers.
We recommend that you use a new logical IP address created only for ETERNUS SF Manager.
When allocating a new one, make sure that existing transactions use the IP address as a failover resource and that adding the IP address resource has no adverse effects on transactions.
If you use an existing logical IP address, share it with ETERNUS SF Manager in order to make sure that no trouble occurs with any other product already using this logical IP address.
Shared disk for shared data
Volume for storing shared data of ETERNUS SF Manager.
With regard to such factors as reliability and update performance, we recommend that you use a new volume created only for ETERNUS SF Manager.
Note
When you specify a shared disk for shared data, be careful about the following points:
- Define the shared disk for shared data as a shared disk of a cluster.
- Allocate a disk that does not use AdvancedCopy Manager to carry out backup and replication.
- Allocate a disk that is not used by AdvancedCopy Manager CCM as a copy source, copy destination or access volume.
- On the shared disk for shared data, create a file system.
- In order to be used by the file system, make the shared disk mountable.
- Use a disk that is not used as a Quorum disk.
Refer to "Dynamic Disk Space" in "Operating Environment for ETERNUS SF Manager" in the ETERNUS SF Installation and Setup Guide for information on the disk space required for ETERNUS SF Manager.
Disk resource of shared disk for shared data
Disk resource name of shared disk for shared data.

Resource type
Procedure resource and command line resource.

Cluster name
Cluster name specified in WSFC.
Network name
Dedicated network name for ETERNUS SF Manager that is specified when using a new logical IP address.
ETERNUS SF Manager creates a network resource under this network name.
Network for external connections
Network name for external communication specified in WSFC, to be specified when using a new logical IP address.
IP address resource
IP address resource name in which logical IP address is set up, to be specified when using an already existing logical IP address.

Generic script

Script for starting or stopping services/daemon.

For Windows version

Create generic script files for starting and stopping the following services:

ETERNUS SF Manager Apache Service
ETERNUS SF Manager Tomcat Service

Create the following script file separately for each service.
You can freely specify any file name, but the file extension must be ".vbs".

Function Online()

    Dim objWmiProvider
    Dim objService
    Dim strServiceState

    ' Check to see if the service is running
    set objWmiProvider = GetObject("winmgmts:/root/cimv2")
    set objService = objWmiProvider.get("win32_service='serviceName'")
    strServiceState = objService.state

    If ucase(strServiceState) = "RUNNING" Then
        Online = True
    Else

        ' If the service is not running, try to start it.
        response = objService.StartService()

        ' response = 0  or 10 indicates that the request to start was accepted
        If ( response <> 0 ) and ( response <> 10 ) Then
            Online = False
        Else
            Online = True
        End If
    End If
End Function

Function Offline()

    Dim objWmiProvider
    Dim objService
    Dim strServiceState

    ' Check to see if the service is running
    set objWmiProvider = GetObject("winmgmts:/root/cimv2")
    set objService = objWmiProvider.get("win32_service='serviceName'")
    strServiceState = objService.state

    If ucase(strServiceState) = "RUNNING" Then

        response = objService.StopService()

        If ( response <> 0 ) and ( response <> 10 ) Then
            Offline = False
        Else
            Offline = True
        End If
    Else
            Offline = True
    End If
End Function

Function LooksAlive()

    Dim objWmiProvider
    Dim objService
    Dim strServiceState

    set objWmiProvider = GetObject("winmgmts:/root/cimv2")
    set objService = objWmiProvider.get("win32_service='serviceName'")
    strServiceState = objService.state

    if ucase(strServiceState) = "RUNNING" Then
        LooksAlive = True
    Else
        LooksAlive = False
    End If
End Function

Function IsAlive()

    Dim objWmiProvider
    Dim objService
    Dim strServiceState

    set objWmiProvider = GetObject("winmgmts:/root/cimv2")
    set objService = objWmiProvider.get("win32_service='serviceName'")
    strServiceState = objService.state

    if ucase(strServiceState) = "RUNNING" Then
        IsAlive= True
    Else
        IsAlive = False
    End If

End Function

Instead of serviceName in the script, enter the corresponding service name (one of the following):

esfmanagerweb
esfmanagertomcat

For Solaris or Linux version

Create generic scripts (Start/Stop/Check) for the following daemons.

ETERNUS SF Manager Apache daemon
ETERNUS SF Manager Tomcat daemon
ETERNUS SF Manager Postgres daemon

Create the generic scripts according to the following settings. Specify the unique names to the files.

Start script	root	root	544
Stop script	root	root	544
Check script	root	root	544
