Just wondering if I could get advice on the best way of creating a server 2012 R2 Hyper-V template and rolling it out to identical hardware multiple times. I only have access to Microsoft and any freeware apps.
I'm using a HP c7000 enclosure with ProLiant BL460c G7 servers and flex 10 modules. The flex modules are running two Ethernet networks carrying the same VLANs. This if for redundant links for the HP enclosure environment. Basically I have created a template server, which is quite basic.
After creating a RAID 1 array for the OS and installing it, these are the only settings changed.
Enable icmp in
Enable remote desktop
Enable nic teaming – default settings here(switch independent mode, dynamic load balancing with both adapters active)
Install the hyperv role – within here the virtual switch is set on the Nic team.
There's more to do but I can fix the image later.....
The switches LACP or in HP’s terms “bridge aggregation groups” which connect to the flex 10 modules are permitting all vlans through.
Basically everything is running as intendend, we can fire up VM’s and put them on any VLAN we want. I have taken an image of this server (using windows backup). When I restore this image onto another server and then run sysprep, after the reboot we lose the nic teaming and network connectivity as a whole. We then log in via the ILO to sort it out. Is there a way to preserver this nic teaming, or is there a better way in general to deploy these servers.
After I install the image onto the server the nic teaming is preserved, however there is a mac address conflict with the original server from where the image was taken. After sysprep, I think it solves this problem, but the teaming is lost.
I’m sure there’s better ways to do it.
