For example, to export slice 0 of the physical disk c1t57d0 as a virtual disk, you must export the device that corresponds to that slice (c1t57d0s0) as follows.
primary# ldm add-vdsdev /dev/dsk/c1t57d0s0 c1t57d0s0@primary-vds0
You do not need to specify the slice option because a slice is always exported as a single-slice disk.
For example, assign the disk (pslice) to guest domain ldg1.
primary# ldm add-vdisk pslice c1t57d0s0@primary-vds0 ldg1
ldg1# ls -1 /dev/dsk/c0d13s* /dev/dsk/c0d13s0 /dev/dsk/c0d13s1 /dev/dsk/c0d13s2 /dev/dsk/c0d13s3 /dev/dsk/c0d13s4 /dev/dsk/c0d13s5 /dev/dsk/c0d13s6 /dev/dsk/c0d13s7
Although there are eight devices, because the disk is a single-slice disk, only the first slice (s0) is usable.
