HP-UX GUID Manager v1.0 Administrator Guide

1.3 WWN States
A WWN managed by the GUIDMgr can be in one of five states in the database:
• FREE — The WWN is available for assignment to a vPar, either by manually specifying the
WWNs or by requesting them from the GUID server.
• EXTERNAL – The WWN has not been assigned to a vPar yet. While in this state, the WWNs
are not automatically handed out to another requestor.
NOTE: This is usually a transitory state to INUSE. The WWNs may be held by a third party
like Virtual Server Manager.
• INUSE – The WWNs have already been assigned to a vPar. While in this state, the WWNs
are guaranteed not to be automatically handed out to another requestor.
• EXCLUDED – The WWNs have been removed from a vPar. While in this state, the WWNs
are guaranteed not to be automatically handed out to another requestor.
• FOREIGN – The WWNs are outside of our OUI but they are tracked in order to return a
warning should they be reused by another Virtualization Services Platform (VSP). They never
go into FREE or EXCLUDED state. They are deleted when no longer used.
The EXCLUDED state keeps the GUID Manager from re-assigning a WWN to another vPar after
the vPar is either removed or modified. Because there is storage associated with the WWN, these
WWNs should not be givien automatically to another vPar. If you need to recreate the vPar after
removing it, you can manually specify the WWNs to recover them. Using the GUID Manager
guarantees that the WWNs are not automatically assigned again.
NOTE: FOREIGN WWNs are never set to INUSE. The GUID Manager has no control of their
management, but it tracks those WWNs that have been assigned to a vPar , and deletes them
when a request is received.
