To update an existing SANmp installation, you must first uninstall any previous versions of SANmp. These guidelines outline the proper steps for a successful update procedure:
  • Verify that all computers meet the minimum system requirements for the version of SANmp you are installing.
  • Backup any critical data before performing any updates – SANmp or otherwise. While updating application software is generally non-invasive, it’s better to be safe.
  • Disconnect the workstations from the SAN fabric that you will be updating. Without SANmp installed, the operating system will not recognize the SANmp configured storage correctly and could cause data loss.
  • Uninstall SANmp (Admin and Client) using the installer package specific to the version of SANmp that you are uninstalling. Each version of SANmp has various application files, driver files, and other support files that are installed in specific locations. If these files are not removed prior to the installation of a new version of SANmp, it may cause not only SANmp – but other applications, workstations and servers, and the SAN infrastructure itself to experience instability. Only the installer package for the version of SANmp that you wish to uninstall will reliably remove all of these files. Once the uninstall is finished, restart the workstation, then proceed with the installation of the new version of SANmp.
  • Install the latest version/build of SANmp that is compatible with your computer. When the installation is complete, shut down the computer, reconnect it to the SAN, and power up the machine. Update one workstation at a time (if possible) and test access to the SAN; this will make it easier to troubleshoot and isolate any potential issues.
  • Verify that all SAN connected workstations are running the same version of SANmp.
Depending on your installed version of SANmp, these instructions and more details can be found in the installed User Guides.
