Hi Folks
Ive seen other threads relating to similar issues but nothing that left me confident to start bludgeoning the OS so any measured suggestions appreciated. Essentially, the extra 4-port ethernet card has lost 2 of its interfaces since upgrade to v6 (denoted rename 7 and rename8 below). Any suggestions to bring them back appreciated! (HP DL380 G7)

sometimes these issues are resolved by installing the latest BIOS/Firmware for all components of the machine (as far as I remember there were quite a few cases of similar problems where HP servers worked after an update)

I hope this helps!
 
Hi Stoiko as far as im aware it has latest bios/firmware so I dont think thats the route forward. any other thoughts appreciated though
 
Hi @Stoiko Ivanov ,
i have the same problem with Broadcom Limited NetXtreme II BCM5709 Gigabit Ethernet (rev 20) a little more network processing and i lose connection!

sadly not really - I would check the journal after booting up - maybe there's a message related to the NICs - I'd search for those in the internet

does not sound related to me? - the original problem is that NICs are presented as rename0 and so on - you describe a lost of connectivity -> open a fresh thread and provide some logs and describe your setup (e.g. by providing your /etc/network/interfaces)
 
@Stoiko Ivanov ,
my /etc/network/interfaces :

GNU nano 3.2 /etc/network/interfaces

# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!
