The imagebuilder, updatemgr, vsan-health services failed to start due to timeout post vCenter server patching activity and hence the upgrade is marked failed.
This issue is resolved in VMware vCenter Server release 7.0 U3f. To download go to Customer Connect .
To workaround this issue, please follow the below steps: Take offline snapshot of vCenter Server (vCenter Server virtual machine powered off)Connect to the VCSA command line using the root user via SSH.Make sure all vCenter Server services and running using the below command. #service-control --status --allNote: Some services might be stopped by default. Use cd to go the the below directory: #cd /etc/vmware/vmware-vmon/svcCfgfiles/ Backup all these 3 json files (imagebuilder.json, updatemgr.json and vsan-health.json) using cp command to any other directory. Ex: # mkdir /root/backup -> To create a new directory "backup" under /root # cp imagebuilder.json /root/backup/ # cp updatemgr.json /root/backup/ # cp vsan-health.json /root/backup/ Increase startup timeout ("StartTimeout") value of all these three services to 1500 seconds and save respective json files: Use the vi command to start editing in the file(s). Ex: # vi imagebuilder.jsonLook for the word StartTimeoutPress the i letter to change to insert mode.Change the StartTimeout value to 1500 Press ESC key to exit insert mode.Press :wq! to save and exit. Note: Do the same procedures with (updatemgr.json and vsan-health.json) Perform vCenter server upgrade.
