Upgrading services with no downtime
Can I upgrade the services being provided on a BIG-IP LTM without creating downtime for the client ?
I know you have to reboot after you register with a new key but what about just adding new services on top of already existing ones ? Do you still need a reboot , hence downtime , or is there a trick to work around that ?
- hooleylistCirrostratusHi Ora,
- nitassEmployeei'm not sure but i guess u mean adding add-on feature (license).
- Colin_Walker_12Historic F5 AccountAs hoolio was saying above, nitass, it's possible if they have a redundant pair, and are able to fail traffic over from one to the other. Ideally you'd upgrade the standby unit first, verify all went well, then fail traffic over to that unit, making it the active unit. The original unit could then be upgraded, and clients shouldn't see any downtime if all goes well.
- ora_68925NimbostratusWell , as I remember on Linux machines if you do an update in CLI you can reboot the daemon running the service without logging out or rebooting the machine.
- hooleylistCirrostratusAre you asking about adding module addon keys to an existing license? For 9.x you must reboot. For 10.x you don't need to, but daemons may be restarted. Either way, I suggest activating the new license on the standby unit, failing over during a maintenance window and then activating the new license on the peer unit.
