如果成功执行，则命令不会显示输出。要验证命令是否成功并查看确切的 分区命名，用户可使用这些命令查看分配的完整分区名称。

#cd /dev/mapper

#ls

一般映射格式的部分示例如下：

在 RHEL 主机上，分区节点的格式为 /dev/mapper/mpath<x>p<y>，其 中 <x> 是多路径设备的字母数字编号， <y> 是该设备的分区编号。

在 SLES 11.x 主机上，分区节点的格式为 /dev/mapper/mpath<x>- part<y>，其中 <x> 是分配给多路径设备的字母，而 <y> 是分区编号。

在 SLES 10.3 主机上，分区节点的格式为

/dev/mapper/mpath<x>_part<y>，其中 <x> 是分配给多路径设备的字 母，而 <y> 是分区编号。

注：在多路径设备上创建分区之后，所有 I/O 操作 （包括创建文件系统、原

始 I/O 和文件系统 I/O）都必须通过分区节点完成，而不是通过多路径设备节 点完成。

在 Device Mapper 分区上创建文件系统

使用标准的 mkfs 命令在新建的 Device Mapper 分区上创建文件系统 例如：

# mkfs – t < 文件系统类型 > /dev/mapper/< 分区节点 > 其中 < 分区节点 > 是要在其上创建文件系统的分区。

安装 Device Mapper 分区

使用标准的 mount 命令安装 Device Mapper 分区：

# mount /dev/mapper/<partition_node> <mounting_point>

已可使用

MD3600f 系列阵列上新创建的虚拟磁盘现已设置完毕，并可随时使用。 之后重新引导时，会自动查找多路径设备及其分区。

将多路径驱动程序中的本地驱动器列入黑名单

如果您的多路径驱动程序正在连接到存储区域网络 (SAN)，则它在排除或

将 /etc/multipath.conf 文件中的某些设备 “列入黑名单”时非常 有用。列入黑名单可防止多路径驱动程序尝试使用这些本地设备。

MD3620F, MD3600f specifications

Dell's MD3620F and MD3600F storage arrays are designed for businesses seeking dependable, high-performance storage solutions tailored to meet the demands of modern data management. These models offer a blend of scalability, efficiency, and advanced features, making them well-suited for a range of applications, from virtual environments to critical database operations.

One of the primary features of the MD3620F and MD3600F is their support for a hybrid storage architecture. This approach allows organizations to combine flash storage with traditional hard disk drives (HDDs) to optimize performance and cost. The MD3620F focuses heavily on all-flash configurations, delivering exceptional speed and lower latency, ideal for I/O-intensive workloads.

Scalability is another hallmark of these storage solutions. The MD3600F allows users to scale up to 120 drives, providing robust capacity to meet growing data needs. The MD3620F is engineered for environments where data availability and speed are paramount, with support for high IOPS (Input/Output Operations Per Second) and consistent performance under stress.

In terms of data management, both systems integrate with Dell’s proprietary software, which enhances operational efficiency through features like automated tiering. This technology optimizes data placement between different storage types based on access frequency, ensuring that hot data is readily available while reducing costs associated with less critical data.

Reliability is crucial for businesses that depend on their storage systems. The MD3620F and MD3600F come equipped with advanced data protection mechanisms, such as RAID support, which safeguards against data loss, and snapshot capabilities that provide point-in-time copies of data. Moreover, these solutions include hot-swappable components, ensuring minimal downtime for maintenance and repairs.

Connectivity is also a strong suit of these storage arrays. They support multiple connectivity options, including SAS and iSCSI, allowing for flexible integration into existing IT infrastructures. This adaptability enhances their appeal to a wide range of enterprise environments.

In summary, the Dell MD3620F and MD3600F stand out as robust storage solutions with a combination of hybrid and all-flash configurations, scalability, advanced data management tools, and enhanced reliability features. These characteristics make them ideal for organizations looking to enhance their data storage capabilities while maintaining high performance and efficiency.
