Hi,
I recently updated a 2012 HyperVisor Server from GB iSCSI NIC to a X540-T2 NIC for use with iSCSI.
The System has onboard I350 Nics which I use for the LAN.
Initially I just allowed windows to install best driver (And I presume use the already installed v18 Proset) Things were fine for around 18 hours.
Then I got an event log from IXBGT event ID 56 stating that "Intel(R) Ethernet Converged Network Adapter X540-T2 The network driver has been stopped because the network adapter has been removed." - This brought down all the VM's and although device manager was seeing the NIC's and the NIC's had lights on, they were marked as disabled and could not be re enabled.
After a restart all was fine and then it happened again, around 18 hours later.
I updated the BIOS on the server and attempted to install the latest V19 driver package (changing virtual switch to internal beforehand)
Although the install stated it went ok, immediately it was noticed that performance was poor, and now I cannot see any advanced options within the NIC's - the pane states: "Your Device / OS combination does not support any VLAN advanced settings." (It's not on any VLANs)
The driver on the NIC now shows 05/12/2013 version 3.8.35.0
I will have another out of hours maintenance window soon, what's going on and what should I do ?
Thanks for you advice!
