To make things <BR>> interesting, the old version doesn't even recognize the new servers, <BR>> and the new version is not supported on the old metal except for <BR>> bridge upgrade. Needless to say, the upgrade has to be done with <BR>> minimal downtime, something like 15min to switch would be acceptable,<BR>not more.<BR>> <BR>> I'm planning to proceed as such:<BR>> <BR>> 1) Shut down the pub, while the sub continues
serving the live<BR>network.<BR>> 2) Boot the pub using GRML or such Linux live CD and make a full disk<BR>> copy to external storage. Maybe also break the mirrors and insert<BR>> additional disks to have a physical copy through RAID, putting the<BR>> original disks at a safe place.<BR>> 3) Isolate the pub in a replica of the original network including<BR>> default gateway, DNS and NTP servers as needed. Boot it up again.<BR>> 4) Do the upgrade procedure to 8.6(2) as documented, ending up with<BR>> a bridged upgrade only machine.<BR>> *** Here the docs state I have to also do this to the sub(s). Of<BR>> course I can't, they are serving the live network here. Is this<BR>> fatal, or is my procedure a proper workaround?<BR>> 5) Do a DRS backup of the bridge-upgraded pub.<BR>> 6) Restore the original pub using the copies made in step (2), plug it<BR>> back into
the live network, boot it up and have the live network<BR>> working fully redundant again.<BR>> 7) Install 8.6(2) on a new DL380G6 plugged into the replica network.<BR>> 8) Restore the DRS backup from (5) to this new pub.<BR>> 9) Make sure the pub is working correctly, except for the missing sub.<BR>> 10) Now add a second DL380G6 to the replica network, install 8.6(2) as<BR>> a sub on it, and reestablish the cluster. Manually make sure all<BR>> files in the TFTP server of the original sub are available on the<BR>> new sub as well, as that one isn't restored from backup.<BR>> 11) After making a lot of tests and sanity checks, swap in the new<BR>> cluster in a short downtime window.<BR>> <BR>> Does this plan make any sense? Is there a better one? I'm specifically<BR><BR>> bothered by the documented need to perform the bridged upgrade on all <BR>> nodes in
unison, and then to restore first to the pub, then to all the<BR><BR>> subs. Of course that's impossible without inacceptable downtimes. But <BR>> I assume that I cannot, after step (6), just isolate the old sub in <BR>> the same way as the pub before, doing a bridge upgrade of that <BR>> isolated sub only to get hold of a DRS backup of the sub?<BR>> <BR>> Any hints or ideas welcome,<BR>> TIA,<BR>> Andre.<BR>> -- <BR>> Cool .signatures are so 90s...<BR>> <BR>> -> Andre Beck +++ ABP-RIPE +++ IBH IT-Service GmbH, Dresden <-<BR>> _______________________________________________<BR>> cisco-voip mailing list<BR>> <A href="mailto:cisco-voip@puck.nether.net" ymailto="mailto:cisco-voip@puck.nether.net">cisco-voip@puck.nether.net</A><BR>> <A href="https://puck.nether.net/mailman/listinfo/cisco-voip"
