Linking WWIDs for Snap and Clone Units
LUN WWIDs (World Wide Identifiers) for snap and clone units are different each
time they are created. This causes more system data records to keep track of the
WWIDs as well as script changes at the customer sites. To eliminate this issue, a
linked WWID scheme has been created, which keeps the WWIDs of these units
constant each time they are created.
The WWID of a LUN is 128bits long, and is composed as follows:
Controller Node ID is the 64-bit Fibre Channel node id of the controller pair.
