Comment 1 Mike Foley 2012-01-23 15:38:18 EST
documenting verification steps for QE

1) Configured RHQ server and RHQ agent

1) Start RHQ server and agent
2) Browse to Inventory -> Discovery Queue
3) Stop RHQ server, stop RHQ agent
4) Rename RHQ server folder to something different
5) Start RHQ server, start RHQ agent
6) Browse to Inventory -> Discovery Queue
7) Import the RHQ server detected in the new directory
8) Browse to agent logs

Verification Steps:
1) Verify that the error reported in the BZ is no longer in the loggs
2) Verify that the RHQ server is correctly imported
3) Verify that after Steps 6 there are two RHQ servers in the discovery queue (the one in the folder before renaming and the one in the folder after the renaming).
Comment 3 Heiko W. Rupp 2013-09-01 05:57:35 EDT
Bulk closing of items that are on_qa and in old RHQ releases, which are out for a long time and where the issue has not been re-opened since.
