AdvancedCopy Manager CCM requires the following resources:

Table 4.5 Items required for AdvancedCopy Manager CCM

Items	OS
	Windows	Solaris	Linux
Generic script for AdvancedCopy Manager CCM	Required	Required	Required
Access volume	Required	Required	Required

Each item is explained below.

• Generic script for AdvancedCopy Manager CCM

  Script for stopping the management service of AdvancedCopy Manager CCM.

  Before the shared disk for shared data goes offline, the following service must be stopped.
  In order to stop this service, create a generic script file that executes the acservice stop command with the -lan option. Refer to "acservice stop (management service stop command)" in the ETERNUS SF Operation Guide for Copy Control Module for information on the command.

  • Management service of ETERNUS SF AdvancedCopy Manager CCM

  For Windows version WSFC

  Below is an example of a generic script file.
  You can freely specify any file name, but the file extension must be ".vbs".

  Dim WshShell
  Set WshShell = CreateObject("WScript.Shell")
  
  Function Open( )
      Open = True
  End Function
  
  Function Online( )
      Online = True
  End Function
  
  Function LooksAlive( )
      LooksAlive = True
  End Function
  
  Function IsAlive( )
      IsAlive = True
  End Function
  
  Function Offline( )
      Resource.LogInformation "--- start offline ---"
      Set oExec = WshShell.Exec("installDir\CCM\bin\acservice.exe stop -lan")
      Resource.LogInformation oExec.StdOut.ReadAll
      Resource.LogInformation oExec.StdErr.ReadAll
      Resource.LogInformation "--- end offline ---"
      Offline = True
  End Function
  
  Function Close( )
      Close = True
  End Function
  
  Function Terminate( )
      Terminate = True
  End Function

  Instead of installDir in the script, specify the directory in which ETERNUS SF Manager or AdvancedCopy Manager CCM is installed.

  For Solaris or Linux version PRIMECLUSTER

  The example of creating script as the Start/Stop script for Cmdline resource is shown below.

  #!/bin/sh
  
  case $1 in
  'start')
          exit 0 ;;
  'stop' )
          /opt/FJSVccm/bin/acservice stop -lan
          exit 0 ;;
  esac

  For register a Cmdline resource, specify "start" to the argument for the Start script, specify "stop" to the argument for the Stop script.

  Refer to the manuals of your cluster software for creating procedure of Start/Stop script.

• Access volume

  This is a volume for issuing AdvancedCopy commands from the CCM Server to ETERNUS Disk storage systems.
  It is required for issuing AdvancedCopy commands to ETERNUS Disk storage systems that operate with copy control functions via SAN.

  From among the logical volumes in the ETERNUS Disk storage system to be backed up for AdvancedCopy Manager CCM, connect one logical volume as an access volume to all nodes making up the cluster.

  For Windows

  Make the environment settings for the connected logical volume so as to allow access from all nodes making up the cluster to the same physical disk number (Disk # displayed on the disk management screen).

  For Solaris or Linux

  Make the environment settings for the connected logical volume so as to allow access from all nodes making up the cluster to the same physical device name.

  Note

  When specify a device file of ETERNUS multi path driver to an access volume in Solaris or Linux, setup the device file name and system. Refer to ETERNUS multi path driver manual for details.
