  • 1.  vCenter unavailable after cloning

    Posted Jul 29, 2020 08:35 PM

    Hi,

    I'm testing the upgrade of vCenter 6.5 to 6.7 in a lab. Cloned my DC's, PSC appliance and 4 vCenter Server appliances connected to the PSC. When now starting the appliances in my testlab, the vCenter 5480 interface is accessible, but all services are down.

    When I run "Service control --status", only lwsmd and vmafdd are running, all other services are down. IP has remained the same, name hasn't changed. Only thing that changed is the mac-address. Could this have triggered some certificate changes or becoming invalid?

    I faced the similar issue before with version 6, It was related to the changed MAC address, when you clone the vCenter Server Appliance a new MAC address wil be assigned to the cloned VCSA. It detects that as a new network adapter with without any configuration while the old network adapter is missing.

    Change of Mac address was not the issue, network connectivity was working.

    Turned out the more people had issues with restarting a vCenter appliance when a snapshot is reverted of a running VM, which a live clone essentially is.

    If found the solution in this thread: https://communities.vmware.com/thread/563551

    find /etc/systemd/system/ -lname '/dev/null' -exec ls {} \;

    find /etc/systemd/system/ -lname '/dev/null' -exec rm {} \;

    systemctl daemon-reload

    service-control --start --all

    Later also found this official doc:
