While trying to update our ESXi 5.5 host to 6.0. the error “Cannot run upgrade script on host” occurred at ~93%. After some googling, we found the below website (it referenced ESXi 5.0 but it worked for the 5.5–>6.0 upgrade), whose second option resolved our issue.
The basic resolution steps were…
- disable HA for the cluster
- remove the ESXi host from the cluster
- connect via SSH to the ESXi host and run the following commands to uninstall the FDM agent:
cp /opt/vmware/uninstallers/VMware-fdm-uninstall.sh /tmp
chmod +x /tmp/VMware-fdm-uninstall.sh
/tmp/VMware-fdm-uninstall.sh
- reboot the host
- add the ESXi host back to the cluster
Thanks Keine!
