Boot from SAN applicable only when FIP is disabled on Cisco VIC using FCOE

yakov.shtoots · ‎06-19-2012

Hi,

I have Cisco UCS C200M2 connected to Nexus 5010 with Cisco VIC.

I'm unable to boot from san unless i disable FIP on the VIC from the CIMC.

As long as the FIP is enabled the vfc interface remains in down state (waiting for flogi) until the OS is loading the driver (verified it with ESXi 5 that i've installed on the local storage during troubleshooting this issue).

According to the documentation FIP should be enabled unless explicitly directed by the TAC to disable it.

BR,

Yakov

Hello Yakov,

Please make sure the native vlan configured on Nexus switchport matches the default VLAN defined on vHBA properties on the card.

Reboot of the server is required for the changes to take effect.

If the issue persists, provide us the following information

CIMC version

P81E firmware

OS and driver version

From CIMC CLI,

scope chassis

show adapter 1 detail

show host-fc-if detail

From Nexus switch

show int vfc

show vsan membership

Hi Padramas,

On the Nexus the native vlan is 1

NX5K# show interface ethernet 1/9 switchport

Name: Ethernet1/9

Switchport: Enabled

Switchport Monitor: Not enabled

Operational Mode: trunk

Access Mode VLAN: 1 (default)

Trunking Native Mode VLAN: 1 (default)

Trunking VLANs Allowed: 1-3967,4048-4093

The vHBA configuration was the default which means that Default VLAN was configured to NONE, once i've changed the default VLAN to 1 the vfc has remained in down state even after the ESXi was up and loaded the drivers.

Hi Yakov,

Did you solve the same problem when I try to SAN boot a C220 which is directly connect to the 5548UP.

thanks,
Jeff
