Cause
There is a known product defect with regards to "thin/thinrclm" lun handling, which is fixed in Veritas Volume Manager (VxVM) 5.0 MP3 RP1.
Resolution
In this instance, due to a product defect with VxVM, the following EMC DMX TP (Thin Provisioned) devices are shown as "online thin" by "vxdisk list", however, are not reported by VxVM CLI command "vxdisk -o thin list".
# vxdisk list
DEVICE TYPE DISK GROUP STATUS
disk_0 auto:sliced - - online
disk_1 auto:sliced 50MP1RP5 50MP1RP5dg online
disk_2 auto:none - - online invalid
emc_clariion0_78 auto:sliced - - online
emc_clariion0_79 auto - - nolabel
emc0_0332 auto:cdsdisk - - online thin
emc0_0333 auto:cdsdisk - - online thin
emc0_0334 auto:cdsdisk - - online thin
# vxdisk -o thin list
VxVM vxdisk INFO V-5-1-14413 No Thin Provisioned disk are attached to the system.

Veritas recommends applying the latest rolling patch (Veritas Volume Manaher 5.0 MP3 RP4 "Solaris Sparc" ), due to a series of product incidents resolved in a series of rolling patches.
