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.
