Virtual machine lost network connection after server crash

[graemekeatley]

Hello

I run ESXi 6 on a hosted server i have 3 virtual machines running and recently the server host machine crashed upon restarting none of the virtual machines can get a network connection out onto the internet.  When i created the virtual machines everything was working fine and they had network access with no issues, only warning in my log is as follows:

Device or filesystem with identifier mpx.vmhba38

:C0:T0:L0 has entered the All Paths Down state.

warning

ns3032163.ip-149-202-223.eu

Device or filesystem with identifier mpx.vmhba39

warning

ns3032163.ip-149-202-223.eu

Has anyone any suggestions as to what could have happened?

Are the VMs up and running fine? Try to login to virtual machine using vm console and check if you are able to login. APD message indicates the paths to the lun are lost.

Thanks for the reply yes the vm's are running i have logged in using vsphere client and can access the console , just all vm's now say they have no network connection to internet.  They where working perfectly fine until host crashed.  How should i resolve the lost path to lun i am just new to vmware esxi so not entirely sure

Thanks

Rescan all HBA's on your ESXI and make sure all paths are up. Follow below KB step by step for

VMware KB: Performing a rescan of the storage on an ESX/ESXi host

Thanks that resolved the warnings just my virtual machines still dont have network connection externally but that will be an unrelated issue hoping my hosting compant figure out what they did to cause this as it was working fine

make sure dns is reachable, use nslookup, tracert, ping etc guest commands for network connectivity troubleshooting.
