By reading this page from redhat:
https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Online_Storage_Reconfiguration_Guide/persistent_naming.html
We can learn that only /dev/disk/by-id/... (not /dev/sda or /dev/disk/by-path or /dev/disk/by-uuid) should be used in storage.config for safe reason.

-----------------------------------
using 'by-id' may be a good idea on system that have many disks or have disk name changing issue.
but that will not prevent you from destroy the root disk, we should confirm that the disk is not mounted before disk init.

Yunkai Zhang commented on TS-1161:
----------------------------------
I think there are two kind of problems:
1) Using 'by-id' as persistent name to identify disks maybe can help me to solve TS-667, but we should consider if this method would introduce other problems -- would it cause the mapping(key to disk) changes a lot when replace a new disk?
2) Check if disk was mounted before disk init.
I'm trying to deal with 1) problems firstly.

-----------------------------------
Yeah, don't use e.g. /dev/sda. Use /dev/disk/by-uuid/... or /dev/disk/by-path/... or some such, and make sure you get it right. :)
I guess we could try to detect if a disk is in use, I don't know if there are any portable and reliable ways to detect that (but, I haven't looked). It's not as easy as looking via "mount" etc., you have to take into account various other disk managers, such as LLVM, or even just the software raid layers.
