Mpack package directories for HDP 3.x and Mpack stack

Ensure that you review the Support matrix before you proceed.

As the root user, download the target Mpack in a directory on the Ambari server node. For information on downloading the management packs, see the IBM Spectrum Scale service (Mpack).

Note: The downloaded management pack should be stored and unzipped in a directory that is different from the directory where the currently installed Mpack resides. Ensure that the Mpack directory is preserved for future upgrade use.

For example, the currently installed Mpack is at 2.7.0.3 version and the plan is to upgrade to Mpack 2.7.0.7 version.

In this example, the new (target) Mpack has been downloaded in the /root/GPFS_Ambari/upgrade_Mpack directory. The Mpack contains the upgrade script (SpectrumScale_UpgradeIntegrationPackage) to upgrade the MPack. The upgrade script must be run from the directory that contains the new Mpack.

Ensure that the current Mpack installable package resides on a separate directory on the Ambari server node. This example uses the /root/GPFS_Ambari/currently_installed_Mpack directory. The SpectrumScaleMPackUninstaller.py script used as part of this procedure must be run from the directory that contains the existing Mpack.
