I. Project introduction

Recently, there is a F5 cluster expansion implementation project about 2 VPR and 2 old 5050 Nimm cluster clusters, mainly to solve the performance problems of the old 5000 dual computers, and to expand the performance through VPR.

But each of the two VPR chassis inserts a different card or blade, a 2150 and a 2250

II. Project problems and solutions

2.1.When the command line is ready to modify the interface rate duplex, when the customer specifies the interface, write 1Universe 1.1 as 1.Universe 1.1 and then modify it successfully without reporting an error, but the problem is that there will be a new interface under network-interface that is 1.Universe 1.1, and if you type it wrong again, there may be some more strange interfaces.

Solution: no good solution has been found at present. It is useless to modify bigip_base.conf through vi, and TMSH does not have the command to delete interface directly. At present, you can choose to reinstall directly, but you can't take the configuration with you when you reinstall, otherwise there will still be, and you need to close two DB before installation.

Modify sys db liveinstall.saveconfig disable

Modify sys db liveinstall.moveconfig disable

2.2.When making four NSMs, there is often a VPR plus peer problem, and then the extra time indicates that it is already in the trust-domin.

Solution: there may be your information in the peer list of the other party. Delete it and add it now.

2.3.When four VPR devices are successfully added, the peer devices of one of them will be offline for a while.

Solution: enable multicast Multicast, delete the Multicast, and resume using unicast failover communication!

2.4. when doing dual computers and cluster, we should also pay attention to other network basic configuration, naming consistency and so on.
