Abstract

The 9037-001 Sysplex Timer has an announced worldwide end-of-service (EOS) date of December 31, 2003. This critical component of any multi-CPC sysplex will no longer be supported by IBM after December 31, 2003.
IBM recommends replacing any 9037-001 models with Sysplex Timer Model 2s (9037-002). The 9037-002 is a full replacement for the 9037-001. There is no upgrade path from the 9037-001 to the 9037-002.
This Redpaper provides the information required for customers to successfully plan for the migration of their 9037-001 Sysplex Timers to 9037-002 Sysplex Timers.
