I am not at work right now can't give ldom detail output:
- I created an guest ldom
- Created a 160GB file on local disk (mkfile -n 160g ldg1)
- Presented this file as hard drive to the ldom
- Partitioned the disk and installed the O.S (Solaris 10)
- Among the slices is one 30GB slice which is no longer required and hence unmounted
I created the 160GB file using mkfile -n command, which i suppose means that the file can grow to a max of 160GB if required. Now since the 30GB slice will no longer be used is safe to assume that the effect size of the file will max out at 130 GB (160 - 30 = 130GB)
Hope this is a bit clear.
Note: LDOM is running fine, there are no issues with either the ldom manager or guest domain. I would just like to know the hard disk space i have for creating future ldoms.

NAME
mkfile - create a file
SYNOPSIS
mkfile [-nv] size [g | k | b | m] filename...
mkfile creates one or more files that are suitable for use as NFS-mounted swap areas, or as local swap areas. When a root user executes
mkfile(), the sticky bit is set and the file is padded with zeros by default. When non-root users execute mkfile(), they must manually
set the sticky bit using chmod(1). The default size is in bytes, but it can be flagged as gigabytes, kilobytes, blocks, or megabytes, with
the g, k, b, or m suffixes, respectively.
-n Create an empty filename. The size is noted, but disk blocks are not allocated until data is written to them. Files created with
this option cannot be swapped over local UFS mounts.
-v Verbose. Report the names and sizes of created files.
USAGE
See largefile(5) for the description of the behavior of mkfile when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).
