Re: [AG-TECH] [AG-L] APAG & AccessGrid server upgrade

Everything about the APAG services remains the same. The IP address of the AccessGrid.org bridge has changed - a purge of the bridge cache should find it. The last step in the upgrade is the physical relocation to another building of the machine providing the services. It was to have been done last weekend but that didn't work out and my current plan is to do the move late afternoon or evening on day this week. At the moment, I'm planning it for Wednesday 26th (tomorrow) at 4pm Brisbane time (5pm AEDT) - hoping that will be late enough not to disrupt any running AG sessions. The move will entail an outage of all AccessGrid.org and APAG services for approximately half an hour. If anyone will be inconvenienced by an outage at that time, please let us know as soon as possible so we can organise another time (probably same time Thursday 27th). There'll be no further change of IP addresses, or anything else, due to the physical move of the hardware. Everything should just work! chris On 25/03/2014, at 11:52 AM, Jason Bell <j....@cq...> wrote: > Chris > > Been meaning to ask - in the event of the update, did the IP addresses of the Unicast bridges change at all? > > Regards, > Jason. > > -----Original Message----- > From: acc...@li...

A new bridge is running with name "AccessGrid.ORG" to distinguish it from the old "AccessGrid.org" which I left running for a while in case the new system didn't work. Its been running for a few days without any apparent problem during local testing. It would be appreciated if anyone has time to test it further - purge your bridge cache to find the new bridge and then use it for a while (and report any problems) >> - new AudioReflector (in both APAG & AccessGrid.org servers' "Service Lobby") is up & running >> >> Still to be done: >> - although the APAG server vm is built (and running with a different ip address while testing), I wanted to delay final change over to a convenient (or least inconvenient) time for everyone. I'd normally do it at a weekend but thats not possible this weekend, so I'm suggesting Monday 24th morning (Brisbane time). Please let me know if thats a bad time e.g. if anyone has a meeting scheduled around then, otherwise there'll be a down time of hopefully less than half an hour of all APAG services. >> >> chris >> >> >> Christoph Willing +61 7 3365 8316 >> Research Computing Centre >> University of Queensland >> >> >> >> >> _______________________________________________ >> accessgrid-l mailing list >> acc...@li... >> https://lists.aarnet.edu.au/mailman/listinfo/accessgrid-l > > Christoph Willing +61 7 3365 8316 > Research Computing Centre > University of Queensland > > > > > _______________________________________________ > accessgrid-l mailing list > acc...@li... > https://lists.aarnet.edu.au/mailman/listinfo/accessgrid-l > > _______________________________________________ > accessgrid-l mailing list > acc...@li... > https://lists.aarnet.edu.au/mailman/listinfo/accessgrid-l Christoph Willing +61 7 3365 8316 Research Computing Centre University of Queensland |
