Enhancement for mechanism to regulate Volume Manager Access for disks Provisioned across nodes.

Enhancement requested to restrict/regulate accidental provisioning of same disk (storage LUN) to multiple nodes at volume manager level(LVM) :

In a customer environment multiple servers ,multiple LPAR's are managed by a SAN/NAS backed storage. It's being observed that a disk/LUN/Physical-Volume that is provisioned to a system/node is being presented/provisioned to another system/node as a fresh disk .
This being done by customer accidentally/by mistake/typo/unknowingly or sometimes with lack of knowledge.

System logs captures only the details of the system/Node and no idea on its storage mapping of other Node's it will be hard to debug many file system corruption and Volume manager metadata corruption cases. When the other System/Node corruption issue observed , then its realized that both are related and can conclude that same disk was presented on both the Node's that caused the corruption on both Node's VG's.

Thus request the enhancement to prevent this scenario happening at Volume Manager's level
which gives admin error/warning with information about other Node(s) where the disk/LUN presented.
Thus admin has to check back their storage mapping configurations to prevent this scenario.
