It means a concatenation of two partitions, end-to-end, into one partition.
If you had something like:
That would mean to stripe the two partitions into one partition.
Ie they are again added together, but this time in stripes across the whole new partition.

Hello,
I have a scsi pci x raid controller card on which I had created a disk array of 3 disks
when I type lspv ; I used to see 3 physical disks ( two local disks and one raid 5 disk )

scan_ffs
SCAN_FFS(8) BSD System Manager's Manual SCAN_FFS(8)NAME
scan_ffs, scan_lfs -- find FFSv1/FFSv2/LFS partitions on a disk or file
SYNOPSIS
scan_ffs [-blv] [-e end] [-F file] [-s start] device
DESCRIPTION
scan_ffs will take a raw disk device that covers the whole disk or a file and will find all possible FFSv[12]/LFS partitions, independent of
block sizes on it. It will show the file system type (FFSv1, FFSv2, or LFS), size, and offset. Also it has an option to show the values
with a disklabel-alike output.
The options are as follows:
-b Report every superblock found with its sector address, rather than trying to report the partition boundaries. This option can
be useful to find the other superblocks in a partition if the first superblock has become corrupted. It is most useful if
device refers to the raw device for the partition, rather than the entire disk.
-e end Where to stop searching for file systems. The end argument specifies the last sector that will be searched. Default is the
last sector of device.
-F file Path to a file containing possible partitions inside of it.
-l Print out a string looking much like the input to disklabel. With a little massaging, this output can usually be used by
disklabel(8).
-s start Where to start searching for file systems. This makes it easier to skip swap partitions or other large non-UFS/FFS partitions.
The start argument specifies the first sector that will be searched. Default is the first sector of device.
-v Be verbose about what scan_ffs is doing, and what has been found.
The device argument specifies which device scan_ffs should scan for file systems.
scan_lfs is just another name for the same program, both behave in exactly the same way.
SEE ALSO disklabel(8)HISTORY
The scan_ffs program first appeared in OpenBSD 2.3 and then in NetBSD 3.1. Support for searching in files was added in NetBSD 4.0.
AUTHORS
scan_ffs was written for OpenBSD by Niklas Hallqvist and Tobias Weingartner. It was ported to NetBSD by Juan Romero Pardines, who added sup-
port for LFS/FFSv2, partitions with fragsize/blocksize greater than 2048/16384 for FFSv1, searching on files, etc.
BUGS
Currently scan_ffs won't find partitions with fragsize/blocksize greater than 8192/65536.
