Version 1.1 – Added automatic VLAN assignment to newly PG based on node’s mgmt vmk
Hello vCommunity,
Here is a simple script to recover the network communication between VCSA and PSC when they have vDS Port Groups assigned and somehow they lost connection and cannot communicate with each other.
Important: This script prompts you do pick a vmnic1 to disconnect and connect to the temporary vSS it creates, make sure the selected vmnic passed the vcsa/psc traffic and it supports the VLAN (if declared)
Now the VLAN gets automatically assigned grabbing the ESXi’s management vmk (vmk1 Quanta / vmk2 Dell)
Regular Script
[[email protected]:~] sh net-recoveryvc.sh
Note: The name is optional, you can call it whatever you want.
Output:
