\_ round-robin 0 [prio=6][active]

\_ 1:0:0:2 sdf 8:80 [active][ready] \_ round-robin 0 [prio=0][enabled]

\_ 0:0:0:2 sde 8:64 [active][ghost] 在此示例中, mpath6 设备包含两个路径:

--/dev/sdf at Host 1, Channel 0, Target 0, LUN 2 --/dev/sde at Host 0, Channel 0, Target 0, LUN 2

3使用以下命令清洗多路径设备映射:

# multipath -f /dev/mapper/mapth_x

其中 mapth_x 是您要删除的设备。

4使用以下命令删除与此设备相关的路径:

# echo 1 > /sys/block/sd_x/device/delete

其中 sd_x 是多路径命令返回的 SD 节点 (磁盘设备)。对与此设备相 关的所有路径重复此命令。

例如:

#echo 1 > /sys/block/sdf/device/delete

#echo 1 > /sys/block/sde/device/delete

5MDSM 中移除映射,或删除 LUN (如有必要)。

6如果您要映射其它 LUN 或增加容量,通过 MDSM 执行此操作。

注:如果您只是在测试 LUN 删除,则可在此步骤上停止操作。

7如果新的 LUN 已映射或容量发生变化,请执行以下命令:

#rescan_dm_devs

8使用 multipath -ll 命令以验证:

新的 LUN 是否映射、新的 LUN 是否检测到、以及是否给定多路径 设备节点。

如果您增加卷容量,则会显示新容量。

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.
