示例：为 Sun Cluster 配置 SRDF 复制组
本示例用于完成在群集中设置 SRDF 复制所需执行的特定于 Sun Cluster 的步骤。本示例假定您已执行以下任务：
-
已针对阵列间的复制完成 LUN 配对。
-
在存储设备和群集节点上安装了 SRDF 软件。
本示例涉及一个四节点群集，其中两个节点连接到一个 symmetrix，另外两个节点连接到第二个 symmetrix。SRDF 设备组名为 dg1。
示例 5–15 创建副本对
在所有节点上执行以下命令。
# symcfg discover
! This operation might take up to a few minutes.
# symdev list pd
