Virtual Connect server profiles 168
• The corresponding physical functions for each port on the same adapter must have the same
personality. For example, if MZ1:1-b is iSCSI, MZ1:2-b must also be iSCSI; it cannot be Ethernet.
• PXE and iSCSI can be enabled at the same time on a single port (PXE on a, iSCSI on b).
• PXE and FCoE can be enabled at the same time on a single port (PXE on a, FCoE on b).
• FCoE and iSCSI cannot be enabled at the same time on a single port, since they use the same PF.
After the iSCSI connections are created in the profile, VCM inventories the LOMs and mezzanines to
determine each of the physical function capabilities, and assigns a personality (Ethernet, iSCSI, FCoE) to
each PF based on connections in the profile and on the PF's capability. VCM sets the boot controller order on
the server. The server boots from the primary iSCSI boot target. If the PF personality has changed, an
automatic reboot is initiated by the adapter. After the server boots, you can configure additional iSCSI
targets from the iSCSI BIOS utility or by using OS tools.
If FCoE connections are configured, VCM sets the FCoE personality to the PF. If FC boot parameters are
configured, VC Manager writes these to the NIC and sets the boot order as it does in the case of iSCSI boot
parameters.
In the first example, a profile with eight Ethernet and two FCoE connections is assigned to a server with a
1-Gb LOM and a dual-port 57711 Broadcom MEZ card in MEZ1 and a CNA in MEZ2. The results of the
mapping algorithm are shown in the following table. Each 1-Gb LOM port only has one connection
assigned.
Device Port Type VC Connections Assigned

1 1 Gb Enet 1
2 1 Gb Enet 2
MEZ1
1 Broadcom 57711 Enet 3, Enet 7
2 Broadcom 57711 Enet 4, Enet 8
MEZ2
1 NC551m Enet 5, FCoE 1
2 NC551m Enet 6, FCoE 2
In the second example, a profile with two iSCSI, ten Ethernet, and two FCoE connections is assigned to a
server with a Flex-10 LOM and NC551m dual-port MEZZ card in MEZZ1 and MEZZ2. The results of the
mapping algorithm are shown in the following table.
Device Port Type VC Connections Assigned

2 Broadcom 57711

2 NC551m Enet 4, FCoE 2, Enet 10
MEZ2
1 NC551m Enet 5, iSCSI 1
2 NC551m Enet 6, iSCSI 2
The third example is similar to the second except that the LOM is the NC551i. The example compares ten
Ethernet, one iSCSI, and four FCoE connections. The second PF on MEZZ2:Port 2 has to be enumerated as
iSCSI since the corresponding PF on port 1 is iSCSI. But, since there is only one iSCSI connection defined in
the Profile, the second PF on MEZZ2:Port 2 is disabled.
