I had some free time on my hands lately, so I decided to fix some of issues in Health Analyzer. I decided on fixing database need to be upgraded error.
I ran following command:
psconfig -cmd upgrade -inplace b2b -force -cmd applicationcontent -install -cmd installfeatures
Which successfully finished first four configuration steps. However, when It got to "Upgrading SharePointProducts" script had displayed following error:
10.00% : Failed to start service SearchServiceInstance on this server after completing upgrade. Please start it manually.
Short googling after, I ran following command, which finished succesfully
stsadm -o osearch -action start
And now I wonder - do I need to restart PSconfig, should I wait for it to continue, or something else?
PS. If it wasn't clear from answer below - yes, you need to restart. It will not continue by itself.
