Software requirements for Direct management

Edit online

There are some software requirements for PowerHA® SystemMirror® Enterprise Edition Metro Mirror.

The following software is required:

  • AIX® level as stated in the support flash
  • Minimum PowerHA SystemMirror version plus all current APARs
  • Java™ Runtime Environment version appropriate for the ESS CLI version installed. (This will be tied to and should be available with the microcode level on the ESS systems.)
  • ESS CLI as appropriate for your storage microcode (LIC) level:

    The ESS Copy Services CLI software is closely tied to the ESS microcode level. CLI code is found on the MegaCDR that is included in the Customer Software packet.

    • IBM® 2105 Command Line Interface (ibm2105cli.rte )

      or

    • IBM 2105 Command Line Interface (ibm2105esscli.rte) (also included on the MegaCDR).

    Depending on which version of the ibm2105esscli fileset ships with your level of ESS microcode, the files will be installed in one of three locations:

    1. /usr/opt/ibm2105cli
    2. /usr/opt/ibm/ibm2105cli
    3. /opt/ibm/ESScli

    PowerHA SystemMirror Enterprise Edition assumes a default directory for the ESS CLI executables. Therefore, once the CLI executables are installed in one of the directories listed, you must create the following link:

    /usr/opt/ibm2105cli -> < ESS cli installation location >

    so that PowerHA SystemMirror Enterprise Edition can find the executables.

  • (Optional but recommended) ESS microcode level vrmf 2.4.x.x. This version provides support for a dual active Copy Services Server.
Note: Install microcode vrmf 2.4.x.x on the ESS system to make support for a dual active Copy Services Server available. Otherwise, the Copy Services Server must be manually started on a backup Copy Services Server if the primary Copy Services Server is unavailable.
