本文详细介绍了如何使用Pinning技术在EMCSW的全自动化存储分层（FASTVP）中锁定与特定策略关联的薄设备，以防止数据移动。通过symdev、symsg、symdg等命令，可以实现对单个设备、设备范围、存储组或设备组的锁定操作。

How do I prevent the movement of data related to thin devices under FAST VP control?

EMC SW: Fully Automated Storage Tiering for Virtual Pools (FAST VP)

Enginuity: 5875

Pinning a device that is associated with a FAST VP policy will prevent any data movement for that device. Devices can be pinned individually, by device range, or by device file by using the symdev command. Devices may also be pinned by storage group or by device group by using the symsg and symdg commands, respectively.

Pinning can be performed using Solutions Enabler (SYMCLI).

To pin an individual device, run: symdev -sid ### pin 825

To pin a range of devices, run: symdev -sid ### pin -range 825:835

To pin all devices in a storage group, run: symsg -sid ### -sg storagegroupname pin

To pin all devices in a device group, run: symdg -sid ### dgname pin
