HP Virtual Connect Flex-10 10Gb Ethernet Module for c-Class BladeSystem - Manual (Page 140)

Virtual Connect fabrics 140
• By default, all of the FlexFabric FC-capable uplinks are configured as Ethernet until they are configured
as part of the VC SAN fabric. After the FC-capable uplinks are configured as part of the VC SAN fabric,
the FC SFP transceivers connected to those uplinks become enabled and allow connectivity to the data
center SAN fabric.
• To create a proper Virtual Connect fabric, all VC-FC or FlexFabric module uplinks that are included in
the fabric must be connected to the same SAN fabric as shown in the following figure.
If the VC SAN fabric uplinks are not connected to the same SAN fabric as shown in the following figure,
then the fabric becomes degraded and a log message indicates that the uplinks are connected to
different SAN switches. The WWN of the principal fabric switch indicates connectivity to the same SAN
fabric in Virtual Connect.
