When there is a vdisk presented from CDom to LDom that is not an actual physical disk rather a SVM Softpartition (soft partition) it can cause some issues for the CDom when it's size is dynamically changes.
It is possible to change the size of Softpartition on CDom so the presented VDisk size is increased. The size of the soft partition can be increased after presenting the vdisk.
# metainit d1 -p d0 10g
# ldm add-vdsdev /dev/md/dsk/d1 soft@primary-vds0
# ldm add-vdisk vsoft soft@primary-vds0 solaris10
# metattach d1 15g
d1: Soft Partition has been grown
# metastat d1
d1: Soft Partition
Size: 52428800 blocks (25 GB)
Extent Start Block Block count
0 1024 52428800
After size is increased on CDom, format command in the guest domain still shows old size. format does not offer auto-configure option to be able to re-read current size.
Size of soft partition is increased in primary domain using metattach SVM command.
