Comprehensive and Detailed Explanation From Exact Extract:
To add a new physical disk to LVM, the disk must first be initialized as a physical volume using the pvcreate command. This prepares the new disk for use by the LVM subsystem. After initializing with pvcreate, you would use vgextend to add the new physical volume to an existing volume group.
Other options:
A. vgextend adds a physical volume to a volume group, but you must use pvcreate first.
B. lvextend is used to increase the size of a logical volume, not to add a new disk.
D. pvresize is used to resize an existing physical volume, not to create one.
