Use the vxdisk reclaim command to trigger online Thin Reclamation on one or more disks, disk groups, or enclosures. The following example triggers reclamation on LUNs disk1 and disk2:

# vxdisk reclaim disk1 disk2

You can only perform Thin Reclamation on thin_rclm LUNs. VxVM automatically discovers LUNs that support Thin Reclamation from capable storage arrays. To list devices that are known to be thin or thin_rclm on a host, use the vxdisk -o thin list command.

You can only perform Thin Reclamation if the disks support a mounted VxFS file system.

For more information on how to trigger Thin Reclamation on a VxFS file system, see the Veritas File System Administrator's Guide.

Thin Reclamation takes considerable amount of time when you reclaim thin storage on a large number of LUNs or an enclosure or disk group.
