We have DAG1 with two nodes Ex 2013 CU13 & DAG2 also with 2 Node Ex 2013 CU13 all hosted on Windows 2012 R2.
We successfully updated the two nodes in DAG 1 from Ex 2013 CU13 to CU23.
But while updating the Node1 in DAG2, we encountered the following error during 3/15 progress stage of the GUI wizard.
" Couldn't remove product with code 4934d1ea-be46-48b1-8847-f1af20e892c1. The installation source for this product is not available. Verify that the source exists and that you can access it. Error code is 1612."
With this error the node is stuck in Maintenance mode. We cannot Set ServerComponentState ServerWideOffline to Active.
The command "Set-ServerComponentState EXNode12 -Component ServerWideOffline -State Active -Requester Maintenance" executes without any error but the state of the component does not change to Active.
Help much appreciated.
