Instructions
虚拟设备 (VDEV) 是 SNAP作的目标,正用作 IBM DFDSS 实用程序的输入,以转储到磁带。
错误消息:
ADR735W (001)-T0MI (06), 2009.199 03:23:02 USE OF CONCURRENT COPY FAILED FOR VOLUME APFI55,014.
SERIALIZATION WILL BE HELD AND
ARC0640I ARCDVOL1 - CONCURRENT COPY WILL NOT BE USED
并发复制尝试将 00xx SNAP 会话放在 DFDSS作的源设备上。并发拷贝是不拷贝快照作。并发复制作失败。原因发布在 《TF/Clone Mainframe Snap Facility for z/OS V 10.2.0 产品指南》第 90 页中:
"A virtual device (VDEV) cannot have a relation with any target device."
DFDSS 复制作成功完成,允许将 VDEV 转储到磁带。
但是,不使用并发拷贝。系统会发出返回代码 4 以及针对作业ADR735W的警告消息。
