Method used to reclaim thin LUN space

You can use the following methods to reclaim thin LUN space:
1. Manually set the space size to zero.
In this method, use a command to set the space value of the released space on a host to zero and reclaim the space. During the operation, the thin LUN space is fully occupied. Before performing this operation, you must stop services on thin LUNs.
2. Enable a storage system to automatically reclaim the released space.
If the operating system on a host support thin LUNs, the operating system can identify the released space and deliver a specified SCSI command to a storage system. Then, the storage system will reclaim the released space.
