红帽全球峰会第 5 章 配置块存储服务
在将块存储服务配置为使用新的 Fujitsu ETERNUS 后端后，为每一个服务声明 卷类型。卷类型允许您指定在创建新卷时要使用的后端。以下命令创建两个卷类型： FJFC （用于光纤通道后端）和 FJISCSI （用于 iSCSI 后端）：
# cinder type-create FJFC
# cinder type-create FJISCSI接下来，将这些卷类型映射到对应的后端（在 第 2 章 定义 iSCSI 或光纤通道后端 中定义）：
# cinder type-key FJFC set volume_backend_name=FJFC
# cinder type-key FJISCSI volume_backend_name=FJISCSI
