Chris Chau Posted March 24, 2023 Share Posted March 24, 2023 Hi Simon, Have you ever tried uploading the support bundle to CIS (https://cis.citrix.com/) for a quick analysis? This is the supporting tool and everyone can use it via your Citrix account credential. Once you log in, go to "Workspace" and click "Tools". Following the dialog, you can upload the support bundle file and it will automatically analyse all the logs for you.After a while, an email will be sent to you, with the link for you to read the result.See whether this online tool could help you troubleshoot first. Surely, any NetScaler with a valid support maintenance could also open a support case in your scenario. Link to comment Share on other sites More sharing options...
Simon Cooper Posted March 24, 2023 Author Share Posted March 24, 2023 Chris,Yes, we uploaded the support bundle from the current Primary to CIS and it didn't show anything of note.We have issues with uploading the support bundle for the secondary, CIS reports it is corrupt and we have a ticket open for this with Citrix.I was wondering, as I can unzip the the support bundle and all looks fine, if there was anywhere within the files were I can look and maybe see why the failover happened?thanks for the response, appreciatedSimon Link to comment Share on other sites More sharing options...
Chris Chau Posted March 25, 2023 Share Posted March 25, 2023 Oh. Then I think I will let our techsupport to give you an professional answer as there must be other log files providing more visibility and deep investigation.Just one thing: normally, I would look into the ns.log files (maybe zipped into different versions already) around the failover timestamp and from that file, looking for any abnormal events happened around/before the failover happened. Surely, it might just give you the abnormal event (e.g. link down). The root cause behind that might need further analysis. Link to comment Share on other sites More sharing options...
Terry Hooper Posted March 28, 2023 Share Posted March 28, 2023 Hi,Within ADM you should see the corresponding event log which may give you an indication of the failure (screenshot details lost heartbeat etc.). Link to comment Share on other sites More sharing options...
Simon Cooper Posted March 28, 2023 Author Share Posted March 28, 2023 Hi Terry,appreciate the response, but ADM shows nothing. There are no events showing for the time or even the date of the failover. Link to comment Share on other sites More sharing options...
