Fabric
Server
When using HBA NPIV, consider the following:
• When a VOS initializes, the HBA performs a fabric login using the manufacturing-assigned
WWPN, and the switch assigns a FCID for the login session. The HBA WWPN and associated
FCID are logged in the fabric name server.
When an NPIV-enabled VM initializes, the HBA performs another fabric login using the virtual
WWPN associated with that VM, which creates another FCID and entry in the fabric name
server. This process is repeated for each NPIV-enabled VM.
• When a VM stops, the entry is removed from the fabric name server. The relationship between
FCIDs assigned to multiple N_Ports logged in on the same F_Port is not defined by the
standards; instead, the switch vendors provide implementation details. In Figure 64 (page
178), the FCIDs have common values for the WWPN domain and area fields, and the port
field value is incremented for each new login.
NonStop servers (XP only)
NonStop servers are supported in direct host attach and SAN configurations for specific storage
systems.
