If you update VCSA (vCenter or PSC) 6.0 U1 using VAMI (patching directly from internet or using local repository/mounted iso), the update may hang at 70%.
If you face this problem, you need to check the update log /var/log/vmware/applmgmt/software-packages.log on VCSA (using SSH) and find a line similar: “UpdateTask: status=completed, percent=100”. It means the update is completed and you can reboot the VCSA.
You can use the following command (#bash needs to be enabled):
cat /var/log/vmware/applmgmt/software-packages.log | grep UpdateTask:”status=completed, percent=100″
If it’s complete your safe to reboot.. if you went cowboy and thought it was broken.. then you broke it by prematurely rebooting it.
With a upgrade via SSH this issue does not happen..
