linux 中的LVM(logical Volume Management)问题求助？

Question

最近在看LVM，看到：
pvcreate /dev/device [/dev/device] ...
The pvcreate command initializes (a) physical device(s) as (a) physical volume(s) (PV). Partitions must have
the partition ID 8E (use fdisk, cfdisk or yast for partitioning), (whole) disks must have no partition table
(none, not just an empty one). To see all physical devices that are available, use the command
lvmdiskscan. The command pvscan shows all existing PVs.

上面提到整个磁盘不能够有分区表，我的问题如下：
1. 安装SUSE时应该要设置分区，这样分区表就存在了，如果安装上系统后，要设置逻辑卷，按照如上说明，需要先删除分区表，才能执行pvcreate,
    删除分区表后，对系统有没有影响，系统还能启动吗？
