Ethernet interface disapeared after firmware upgrade Proliant BL 460c G8

[saki_jumeau]

Hi all,

I have recently upgrade Ilo4 and Rom system firmware  on two blade BL 460c G8 server with solaris 10 OS runing on each node.

ILO4 has been update from 1.13 to  2.00 release and the system Rom from  12/14/2012 to  02/10/204 release.

The upgrade has been done successfuly wih HP service sparc for proliant in offline mode. But  few minute after upgrade the fisrt node lost connextion,  we cannot connect to the OS through ssh but I can through ILO CLI.

 After checking i found that all network interfaces even the one  which has been confirgured (bnxe0 ) are not seen anymore and the IP has disapeared.

bash-3.2# ifconfig -a

lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1

        inet 127.0.0.1 netmask ff000000

lo0: flags=2002000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv6,VIRTUAL> mtu 8252 index 1

        inet6 ::1/128

I also checked the driver nothing is found

#moinfo | grep bnxe

Now i would like to do a rolback by downgrading the firmware to the previous version but I can't with HP SSP. Is there another way to downgrade the firmware to the previous version? How can I do it? or how to retrieve the NIC from OS?

I need your help  and ideas to resolve this issue 

I will appreciad your assistance

Regards,
