4.1.3 Resources required for AdvancedCopy Manager's manager

AdvancedCopy Manager's manager requires the following resources:

Table 4.2 Items required for AdvancedCopy Manager's manager

Items	OS
	Windows	Solaris	Linux
Logical node name	Required	Required	Required
Communication daemon/service port number for transaction	Required	Required	Required
Shared disk for repository	Required	Required	Required
Repository access user	Required	Required	Required
Installing user	Required	Unnecessary	Unnecessary
Start up/shut down script for AdvancedCopy Manager daemon	Unnecessary	Required	Required

Each item is explained below.

• Logical node name

  Name of logical server for AdvancedCopy Manager
  The user can freely set any logical node name, consisting of alphanumeric characters up to 8 bytes.

  In order to determine to which cluster transaction an executed AdvancedCopy Manager function (e.g. backup management command) belongs, AdvancedCopy Manager assigns a unique name (logical node name) to each cluster transaction. By specifying this logical node name in the environment variable SWSTGNODE when running an AdvancedCopy Manager command, the command will identify the applicable cluster transaction and carry out processing accordingly.

  When "Logical IP address" and "Communication daemon/service port number for transaction (stgxfws_logicalNodeName)" are set in the processing for adding the AdvancedCopy Manager server, the applicable cluster transaction is added as a server of AdvancedCopy Manager.

  Note

  13-character strings of the following table cannot be made into a logical node name for Solaris version PRIMECLUSTER or Linux version PRIMECLUSTER.

  Table 4.3 Character strings that cannot be used in logical node names

  audit	cluster	cmdevs	config	daemon	data	java
  log	pid	report	samp	sh	tmp

• Communication daemon/service port number for transaction

  Port number allocated to the communication daemon and service for transactions.

  A port number must be an integer from 1024 to 65535 (from 5001 to 32767, in case of Windows version WSFC) that is currently not being used by another port.

  Also note that the same port number needs to be specified on both the primary and secondary nodes.

  Note

  Ensure that the port number of the communication service for transaction is different from the port number of the communication daemon for local transaction or the other communication services for transaction.

• Shared disk for repository

  Prepare partitions on the shared disk for storing shared data for the AdvancedCopy Manager repository.
  Any of the numbers listed below can be used for setting the number of partitions.

  Table 4.4 Numbers of partitions required for each AdvancedCopy Manager's manager

  Name	Management Server
  Shared disk for AdvancedCopy Manager repository	4, 3, 2, 1, or 0

  Each of the partitions of the shared disk for the repository is used for the database area stored in the following four directories:

  • The directory for database file

  • The directory for RDB dictionary

  • The directory for RDB log file

  • The directory for repository data storage database space

  All of these directories can be created on the shared disk for AdvancedCopy Manager shared data.

  Calculate the required disk space using the size estimate of database. Refer to "Estimation of database size" in the ETERNUS SF Installation and Setup Guide for estimating the size.

  Note

  • Define both the shared disk for AdvancedCopy Manager shared data and the shared disk for AdvancedCopy Manager repository as shared disks of the clustered system.

  • Assign a disk that is not backed up or replicated using AdvancedCopy Manager as the shared disk for AdvancedCopy Manager shared data and the shared disk for AdvancedCopy Manager repository.

  • The four directories can be created on the same shared disk that includes both the shared disk for the repository and the shared disk for AdvancedCopy Manager shared data. However, in consideration of replicability and to upgrade performance, Fujitsu recommends each directory be created in a separate partition.

  • The shared disk for AdvancedCopy Manager shared data and the shared disk for AdvancedCopy Manager repository are used for file systems. Make arrangements so that these disks can be mounted.

  See

  Refer to the manuals of your cluster software and operating system for setting methods for shared disks and for file systems.

• Repository access user

  User name and password for accessing to the repository for Management Server transactions.

  Note

  The local logon authority is needed for Windows version WSFC.

  When the prepared user name is not registered in a system, register it in the system and add the local logon authority to it by cluster setup command. A user name is registered in a primary node and a secondary node.

  It is necessary to register beforehand for all nodes for Solaris version PRIMECLUSTER and Linux version PRIMECLUSTER.

• Installing user

  User name and password that were used when installing ETERNUS SF Manager.

• Start up/shut down script for AdvancedCopy Manager daemon

  It is the script to start up and shut down AdvancedCopy Manager daemon from the cluster application (transaction). Create the script reference to "A.3 Registration of AdvancedCopy Manager service".

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

  #!/bin/sh
  swstgnodedata=<Logical node name>
  
  SWSTGNODE=$swstgnodedata
  export SWSTGNODE
  
  case $1 in
  'start')
          /opt/FJSVswstf/cluster/MgrStart
          exit 0 ;;
  'stop' )
          /opt/FJSVswstf/cluster/MgrStop
          exit 0 ;;
  esac

  Specify the logical node name for <Logical node name>.

  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.
