GDDR:升级到 z/OS 2.5 会导致异常终止和 GDDR 控制系统以降级模式运行

Summary: 升级到 z/OS 2.5 会导致地理位置分散的灾难重启 (GDDR) 异常终止,并且 GDDR 控制系统 (C-SYS) 在降级模式下运行。

Symptoms

大型机作软件更新到 z/OS 2.5 软件级别,具有维护容差。z/OS 2.5 用于新的 IBM z16 CPU。

GDDR GDDRMAIN 在应用 z/OS 维护后启动了几个 ABEND:

  • HBM 在 GDDRMAIN 启动时报告以下错误,GDDR 主机处于降级模式:
ABEND S0E0-29 
  • GDDRRPT 在 GDDRMAIN 关闭时报告以下错误:
ABEND S0E0-28

GDDR 事件监视器 (EVM) 和心跳监视器 (HBM) 输出中会发布以下错误消息:

GDDUG86E No matching GDDR systems found

如果 ABEND S0E0-28 在 GDDRMAIN 关机时发生,然后 Abend S067-04 如果重新启动 GDDRMAIN,则可能会发生这种情况。

Cause

通过 ABEND S0E0-29 在 HBM 子任务的 GDDREVMI 模块 GDDRMAIN 启动时,偏移量 0005AF74 时可能会发生。
PSW 183158F0 0010D507 3000F154       
这会导致 HBM 子任务终止,并使 GDDRMAIN 没有心跳监视功能。GDDR 主机在降级模式下运行。GDDREVMI 已更新为在使用寄存器之前清除寄存器 AR15,以避免 ABEND S0E0-29

此外,一个 ABEND S0E0-28 在 GDDRMAIN 关闭 GDDRMAIN 时,偏移量 0006EAB2 时,GDDRRPT 中可能会发生。
PSW D24FD37A 1000D207 D37D5004
GDDRRPT 已更新以清除 REGISTER AR1,以避免 ABEND S0E0-28。GDDRMAIN 将进行更新,以验证数据空间 2 访问列表条目令牌 ALET) 是否有效。此作在访问另一个 GDDR 实例的数据空间之前完成。此作有助于避免 Abend S067-04 由于另一个 GDDR 实例未完全关闭,在 GDDRMAIN 启动中。

Resolution

解决办法: 

  • ABEND S0E0-29 无,但 GDDR 主机继续在降级模式下运行。
  • 需要逻辑分区 (LPAR) 的初始程序加载 (IPL) 以清除内存,如果 Abend S067-04 发生。                      

永久修复: 

  • 对于 GDDR 6.0,可从 戴尔支持下载程序临时修复 (PTF) GD60004和GD60005。
  • 对于 GDDR 6.1,该问题已在基础产品中解决。它可从 戴尔支持网站下载。
