Knowledge sharing: F5 Software Upgrade/RMA process
Here is quick summary about things should be checked before an F5 upgrade. This is the general F5 support article with clips and there is nice info for VIPRION and VCMP systems: https://support.f5.com/csp/article/K41125752 https://support.f5.com/csp/article/K84554955 https://support.f5.com/csp/article/K84205182 This a great community article 7 Steps Checklist before upgrading your F5 BIG-IP https://support.f5.com/csp/article/K11661449 https://support.f5.com/csp/article/K13081744 Extra addition to the DNS upgrade is that it is better upgrade first the LTM devices that the DNS devices monitor and after the upgrade of 1 or 2 DNS systems till the other DNS systems are also upgraded better upgrade the big3d process on the older DNS systems in the DNS sunc group: https://support.f5.com/csp/article/K15844889 https://support.f5.com/csp/article/K45907236 https://support.f5.com/csp/article/K13734 https://support.f5.com/csp/article/K13312 For BIG-IQ upgrade or for BIG-IQ to upgrade f5 devices: https://support.f5.com/csp/article/K51342220 https://techdocs.f5.com/en-us/bigiq-8-0-0/managing-big-ip-devices-from-big-iq/big-ip-software-upgrades.html For F5 devices with the F5 APM module after upgrade check if the installed F5 Edge Client software needs to be upgraded as it may not work with the new F5 APM TMOS version. https://support.f5.com/csp/article/K13757 An issue I have seen is to install the new version in a volume and transferring the configuration from the old volume to the new but without activating it and then to activate it after a week and there would an old configuration during that week many changes were done on the old volume config, so better before an upgrade so save UCS just in case from the old volume/partition: Some workarounds: https://support.f5.com/csp/article/K82463047 https://support.f5.com/csp/article/K14724 F5 RMA process general articles: F5 general articles for RMA with or withour UCS as without UCS the system and network settings may need to be configured manually and the configuration to be synchronized from the active device to the rma device. https://support.f5.com/csp/article/K12880 For F5 DNS/GTM there are special steps: https://support.f5.com/csp/article/K14083 F5 RMA of VIPRION chassis or a blade as for example when the new blade is installed but the active software version on other blades and vcmp quests is missing then the blade will get stuck in quorum for the chassis or vcmp quest as the primary blade will not be able to update it. If there is single blade in the chassis better hope that there is saved UCS expecially if there are vCMP quests as then for every vcmp quest the system and network need to be manually configured and the other config can be synchronized from the other chassis and vcmp quests that are in HA cluster. https://support.f5.com/csp/article/K14302 https://support.f5.com/csp/article/K16992 https://support.f5.com/csp/article/K23795307?utm_source=f5support&utm_medium=RSS https://support.f5.com/csp/article/K40222952 As the F5 VIPRION chassis is most complex (see K14302) if there is no saved master key as the vCMP quests use keys that are signed by the vCMP host master key and if it is lost then it is really complex, this is a nice F5 devcentral procedure how to generate your own master key that can be the same for the different F5 VIPRION Devices: https://community.f5.com/t5/technical-articles/working-with-masterkeys/ta-p/290454 When loading UCS on the RMA device that has containing encrypted passwords or passphrases, you can check(I have never used the second article but it is nice to have if issues are seen on a vCMP system when a chassis is replaced): https://support.f5.com/csp/article/K9420 Working with MasterKeys https://support.f5.com/csp/article/K13408 The new F5 Joutneys tool can be used for migrating to configuration to the new F5 VELOS and rSeries platforms and maybe in the future the F5 NEXT Operational System. https://community.f5.com/t5/technical-articles/welcome-to-the-f5-big-ip-migration-assistant-now-the-f5-journeys/ta-p/279673 https://www.youtube.com/watch?v=lLm5OkJRicw For the F5 imish/zebos routing module it is good to renember that that the config is not synchronized in a HA pair and before an RMA/upgrade to run the "write" command in the module as this is like the F5 command "save sys config" for CLI made changes as because of the reboot of the devices this changes can be lost. Before the license reactivation I suggest using the tool https://secure.f5.com/validate/validate.jsp to check that you have legitimate license and support contract.
Upgrade from 13.1.3.3 to 13.1.3.6
Hi! This weekend, we have encountered some issues with upgrading with 13.1.3.3 to 13.1.3.6 which forced us to cancel the upgrade. When we arrived on 13.1.3.6 the configuration was empty : no VS, no Real Server....empty. One of my guys presumed that the ciphers for SSL on the new version was different than the one of 13.1.3.3 which caused the box to cancel the import of the configuration. Any idea ? thanks!
