what google says about LVM and SVM?
LVM stands for Logical volume manager which is used in Redhat Enterprise Linux to avoid limitations of the usual hard disk partitions.
SVM stands for Sun Volume manager which is used in sun solaris to avoid the limitations of the hard disk slices. It will support raid configuration where LVM is not.
By using these volume managers, we can create, shrink and expand a filesystem while it is in use. Where a normal filesystem in solaris and linux does not support of shrinking and expanding filesystems online if it is not under the control of volume managers. Fault tolerance and recovery factor is also high.

PVCK(8) System Manager's Manual PVCK(8)
NAME
pvck - check physical volume metadata
SYNOPSIS
pvck [-d|--debug] [-h|--help] [-v|--verbose] [--labelsector] PhysicalVolume [PhysicalVolume...]
DESCRIPTION
pvck checks physical volume LVM metadata for consistency.
OPTIONS
See lvm for common options.
--labelsector sector
By default, 4 sectors of PhysicalVolume are scanned for an LVM label, starting at sector 0. This parameter allows you to specify a
different starting sector for the scan and is useful for recovery situations. For example, suppose the partition table is corrupted
or lost on /dev/sda, but you suspect there was an LVM partition at approximately 100 MB. This area of the disk may be scanned by
using the --labelsector parameter with a value of 204800 (100 * 1024 * 1024 / 512 = 204800):
pvck --labelsector 204800 /dev/sda
Note that a script can be used with --labelsector to automate the process of finding LVM labels.
