在本示例中，ash 和 elm 是 Oracle Solaris Cluster 环境中的节点。主机 ash 为元数据服务器。本示例的 mcf 文件中的 shared 关键字表明这个系统是共享文件系统。
必须在要指定为元数据服务器的节点上创建 mcf 文件。
scdidadm 命令管理设备标识 (device identifier, DID) 设备。-L 选项用于列出所有的 DID 设备路径，包括 Oracle Solaris Cluster 环境中所有节点上的设备。
以下代码示例在 RAID-5 配置中使用 StorageTek T3 阵列。该输出表明可以使用设备 4 到 9 来为共享文件系统配置磁盘高速缓存。

以下代码示例显示了所有 /dev/did 设备的 format 命令输出。您将在创建 mcf 文件时需要此信息。

format 命令显示设备中的可用空间，但不指示磁盘进行了镜像还是进行了分散读写。在此代码示例的 format 命令输出中，显示了在创建如下一个代码示例所示的 mcf 文件期间所需使用的以下信息：
d4s0 和 d6s0 设备的输出表明它们的容量均为 16.86 GB。在 mcf 文件中，为这些设备分别指定了设备编号 501 和 502。它们的大小适于元数据分片使用。
d8s0 和 d9s0 设备的输出表明它们的容量均为 134.88 GB。在 mcf 文件中，为这些设备分别指定了设备编号 503 和 504。它们的大小适于存储数据。
在 "Additional Parameters" 字段中包括 shared 关键字。
将文件系统的 mm 设备置于镜像 (RAID-1) 磁盘中。mm 设备会占用分配给整个文件系统的 10% 的空间。
以下代码示例显示了生成的 mcf 文件。
