KURSINHALT
This course provides an overview of current IBM System z family of servers. It gives detailed information on the System z channel architecture, System z High Performance FICON (zHPF), Fiber connection (FICON) and Enterprise Systems Connection (ESCON) channels, lists operational and protocol characteristics and use of available tools for problem determination (PD) purposes. It discusses operator commands, directors, and Hardware Management Console (HMC)/Support Element (SE) usage for channel problem determination and resolution. Also discussed is the I/O Operations component of System Automation (SA) for z/OS (SA z/OS), Its purpose, and how it is used to manage and assist in PD for large enterprises with FICON and ESON configurations. Hands on lab exercises are included to reinforce lecture topics.Kursziele
