The block device for the LV is added or removed from the system using device-mapper in the kernel. A symbolic link /dev/VGName/LVName pointing to the device node is also added/removed.

-P|--partial Commands will do their best to activate LVs with missing PV extents. Missing extents may be replaced with error or zero segments according to the lvm.conf missing_stripe_filler setting. Metadata may not be changed with this option.
