What is the “volume name” in this context?

From SDK:

\?\Volume{GUID}\

The operating system assigns a unique volume name to a volume when the computer first encounters it

My question is: is the Volume name stored any where in the volume ? If not, is it generated according to some properties of the disk (Inquiry 0x83) ? If not, does it mean it will be inconsistent under Multipath solution.

Thanks

The volume name you refer to is not stored on the volume. I think that
Mark Russinovich covered this pretty well in an article he wrote a few
years back for windowsnt journal or something like that.

Here: http://www.windowsitpro.com/Article/ArticleID/8127/8127.html?Ad=1

It might be an issue for a multipath solution, depending on exactly
what your multipath solution is. If the paths reflect back to the same
physical media and the paths are hidden from the storage stack starting
from disk and above you should be ok.

No. The MountMgr database is in HKLM\SYSTEM\MountedDevices. It maps the “MountDev IDs” to these GUIDs.

When a volume appears, MountMgr asks its MountDev ID and search the map for the GUID. If not found - MountMgr will invent a new GUID and add there. Then MountMgr creates the \?\Volume{guid} symlink.

Drive letters are kept in the same registry database and are derived - in turn - from the volume GUID, this is also the task of MountMgr.

MountDev ID is any BLOB of bytes not interpreted by MountMgr at all - it only compares them for equality. The format depends on the volume manager, but for usual hard disk partition it is 12 bytes - disk MBR signature, then partition offset. For removable devices it is the same as the PnP device interface name for MountDev interface. For software RAIDs like Dynamic Disk it is something invented by the RAID developers.
