Hi Rajasekhar,
The LUN Multi protocol Type, or operating system type, specifies the OS of the host accessing the LUN. It also determines the layout of data on the LUN, the geometry used to access that data, and the minimum and maximum size of the LUN.
Basing on the lun geometry, minimum and maximum sizes can be determined. have a look at this
NAS01> lun show
/vol/Vsphere_vol1/vsphere_lun1 500g (536870912000) (r/w, online, mapped)
NAS01*> lun geometry /vol/Vsphere_vol1/vsphere_lun1
SCSI Disk Geometry:
512 bytes/sector
1024 sectors/track
16 tracks/cylinder (heads)
16384 sectors/cylinder
64000 cylinders
1048576000 sectors
8388608 cylinder size (8 MB)
536870912000 device size (512000 MB)
549747425280 max resize size (524280 MB)
Regards,
Hari.
