Introduction

Before generating the Storage Group script when using Meta LUNs, it is recommended to handle additional meta header information with an external tool called Meta LUNs Mapping tool. The reason for this is that FAST storage groups can only be created with Head members. However, the Precise FAST Integration module can simulate both Meta members and Head members. This tool collects the hierarchy information of all Meta members and creates a properties file. If you select Meta members without using this tool prior to the storage group creation, the storage group creation will fail.

This procedure does not need to be performed for applications without Meta LUNs.

Prerequisites

The following prerequisites are needed on the server on which you are going to use the tool:

  • SYMCLI 6.3 or higher
  • JRE v1.4 or higher and needs to be declared in the path system variable.
  • UNIX root/Windows Administrator permission

Preparing the Meta LUNs properties file

To prepare the Meta LUNs properties file

  1. Copy the folder under <BSO home>\META-LUNS-MAPPING-TOOL to the server where the SYMCLI in installed.

    The folder contains the following files: RunMetaLUNsMapping.bat, RunMetaLUNsMapping.sh, and MetaLUNsMapping.jar.

  2. Run the following file:
    UNIX: RunMetaLUNsMapping.sh
    Windows: RunMetaLUNsMapping.bat
  3. Take the output file (devices.properties) and place it on the server with the Precise Business Storage Optimizer under:
    <BSO home>\webapps\Precise_Storage_Tiering_Simulator\WEB-INF\properties

To control the launch parameters

  1. Copy the folder under <BSO home>\META-LUNS-MAPPING-TOOL to the server where the SYMCLI in installed.

    The folder contains the following files: RunMetaLUNsMapping.bat, RunMetaLUNsMapping.sh, and MetaLUNsMapping.jar.

  2. Run the .JAR file in the following way:
    Java -classpath MetaLUNsMapping.jar
    com.precise.oracle.whatifflash.engine.utils.FASTConvertor.FASTConvertor
    Usage: FASTConvertor <-clihome <SYMAPI-home-folder>> <-offline>
    where:
    -clihome is the SYMCLI solution enabler home (The default SYMCLI home folder in Windows is \Program Files\EMC\SYMCLI\bin\)
    -offline is executing the SYMCLI commands offline without refreshing the database before.
  3. Take the output file (devices.properties) and place it on the server with the Precise Business Storage Optimizer under:
    <BSO home>\webapps\Precise_Storage_Tiering_Simulator\WEB-INF\properties
