This is an Oracle ASM system. ASM disks are not mounted or part of a logical volume. The are used by Oracle:

but return odd status in the ODM:

root@[servername]:/# echo $?
82
82 is code for 'not configured.' This would be expected for an ASM disk.
These ASM disks do correctly report attribute details:
