25.9 Log Files for the Rolling Upgrade

Like many systems managers, we know that you are curious and will want to see "where the bodies are buried" for the Rolling Upgrade. Whether the Rolling Upgrade was successful or aborted, the directory that contains not only the logs, but also all the timelines when each stage is started or completed is in the /cluster/admin/clu_upgrade/history directory.

Let's take a quick look at the contents of this directory.

 # pwd /cluster/admin/clu_upgrade/history

 # ls Compaq.Tru64.UNIX.V5.0A.Rev.1094/   Compaq.Tru64.UNIX.V5.1.Rev.732-1/ Compaq.Tru64.UNIX.V5.1.Rev.732/

 # cd Compaq.Tru64.UNIX.V5.1.Rev.732-1 && ls clean.completed          roll.completed.member2 clean.started            roll.started clu_upgrade.log          roll.started.member1 installupdate            roll.started.member2 installupdate.member     setup.completed patch.completed          setup.started patch.started            switch.completed postinstall.completed    switch.completed.member1 postinstall.started      switch.completed.member2 preinstall.completed     switch.started preinstall.started       tag_files.list roll.completed           tag_files.miss roll.completed.member1

The names of the files speak for themselves. We recommend that you take the opportunity to examine the contents of these files as you perform a Rolling Upgrade on a cluster.
