WWN in the Compute Blade 2000
The Fibre-channel board that can be used in an N+M cold standby system has three different
world wide names (WWNs): Default Physical WWN, Optional Physical WWN, and virtual FC
WWN. These WWNs are described below.
Default Physical WWN
A WWN that is unique and permanent to a specific Fibre-channel board. It corresponds to
the traditional Fibre-channel board WWN. The Default Physical WWN can be shown on
the label attached to the Fibre-channel board.
When setting Fibre Channel over Ethernet (FCoE) as Personality on 10 Gb converged
network adapter (CNA) adapter or 10 Gb CNA board, you can use the Default Physical
WWN unique to the CNA.
Optional Physical WWN
An Optional Physical WWN assigned to a Fibre-channel board: This WWN can be
changed and is used only in Compute Blade. When a Fibre-channel board is replaced,
the Optional Physical WWN remains unchanged, provided the board is installed in the
same slot as before.
When setting FCoE as Personality on 10 Gb CNA adapter or 10 Gb CNA board, you can
assign the Optional Physical WWN to the CNA. Even if you change the 10 Gb CNA
adapter or 10 Gb CNA board, the Optional Physical WWN will not be changed as long as
the new adapter or board is installed in the same slot.
virtual FC WWN *1
A WWN managed by LPAR manager: A unique WWN is generated by LPAR manager for
each LPAR manager system, based on the seed information for virtual FC WWNs. When
a Fibre-channel board is used in LPAR manager mode, the virtual FC WWN is used
regardless of whether the peripheral components interconnect (PCI) device is specified
as dedicated or shared. When a Fibre-channel board is replaced, the virtual FC WWN
remains unchanged, provided the board is installed in the same slot as before.
*1: See "Shared FC Functions" in Chapter 11.
WWN in Basic mode
Partition with N+M cold standby Enabled
Always use the Optional Physical WWN
Partition with N+M cold standby Disabled
When the Smart Configure method is inline, you can select between the Default Physical
WWN and Optional Physical WWN with WWN settings. When the Smart Configure is pxe,
always use the Default Physical WWN.
For Smart Configure method and WWN settings, see “PR Command” in Chapter 6.
By setting the Optional Physical WWN of the Fibre-channel board installed, 10 Gb CNA
adapter, or 10 Gb CNA board installed in the active partition to the fibre channel board, 10 Gb
CNA adapter, or 10 Gb CNA board in the active partition to the Fibre-channel board of the
standby partition, storage area network (SAN) connectivity can be maintained when N+M
switching occurs. In an N+M cold standby configuration, because the WWN as viewed from
the OS on the partition is unchanged after N+M switching, WWN-dependent software
functions such as Persistent Binding can be still available as they are.
