We recently discovered some serious issues when trying to perform SAP software upgrades using SL Toolset 1.0 at support package stack 11 or higher on POWER8 hardware with IBM i 7.1. The problems did not happen when running on older hardware, or when running on POWER8 with IBM i 7.2. The problem could also happen when running an SAP application server Java with a recent patch level of SAPJVM.

PTF 5770999-MF59648 was provided and marked “HIPER” (High Impact/Pervasive) by IBM to solve these problems.

Before attempting any SAP upgrade with IBM POWER8 and IBM i 7.1, it is critical to load and apply PTF 5770999-MF59648.  No special action is necessary if you are running IBM i 7.2. As always, prior to making any major changes in your SAP environment, we recommend updating PTF levels to what is found in the SAP info apar for your IBM i release level.

    Hi Christian,

    Thank you very much for your vital hint and very important input.

    Could we please also have some detail about the error message and SUM phase?

    Best regards,

    Hadi

      Hi Hadi,

      the “error message” was a hard system crash with system reference code (SRC) B600 0103. Because of that it was difficult to identify the SUM phase, but I guess it happens very early in the upgrade.

      Kind regards,

      Christian.
