You can only perform Thin Reclamation on LUNS which have the thinrclm attribute. VxVM automatically discovers LUNs that support Thin Reclamation from capable storage arrays. To identify devices that are known to have the thinonly or thinrclm attributes on a host, use the vxdisk -o thin list command.
To identify LUNs
To identify LUNs that are thin or thinrclm type the following command:
# vxdisk -o thin list DEVICE SIZE(mb) PHYS_ALLOC(mb) GROUP TYPE hitachi_usp0_065a 10000 84 - thinrclm hitachi_usp0_065b 10000 110 - thinrclm hitachi_usp0_065c 10000 74 - thinrclm hitachi_usp0_065d 10000 50 - thinrclm . . . hitachi_usp0_0660 10000 672 thindg thinrclm
In the above output, the SIZE column shows the size of the disk. The PHYS_ALLOC column shows the physical allocation on the array side. The TYPE indicates that the array supports thin reclamation.
