After an upgrad from xenserver 7.5 to 7.6 through the official XenCenter we discovered, that our network configuration is broken. We can provide the following details:
XenConsole:
- network card (Broadcom Nextreme, HP DL380 G6) is detected
- NICs are shown as
OK
- NICs are shown as
NOT CONNECTED
- Management interface has static IP configured
- cables are connected and blinking
- ping to 127.0.0.1 and to NIC IP works
- ping to gateway or other device in the network fails
Already tried:
- emergency network reset
- adding an removing a second PCIe Network card (Intel 1000 pro)
- changing cables on ports
- change of management interface
- several reboots
If we can provide more information just comment what you need and we will try to add it to the questions asap.
Edit: Refering to the comment. The Network card is on the hcl for 7.6 (http://hcl.xenserver.org/networkadapters/28/Broadcom_Corporation_NetXtreme_II_BCM5709_Gigabit_Ethernet)
Edit2: According to the output of /sbin/ifconfig
after trying to ping:
eth1
rx dropped packages: 0eth1
tx: 0xenbr1
rx: 0xenbr1
tx: 2000+ and increasing
So it looks like the bonding of the pyhsical and managment interface is broken.
