In our example, we therefore create the agreement between PSC37 and PSC35, so that in the event of a PSC36 outage, we still have replication with another partner in the field. You can now generate a new replication chord to create a topology of the ring, you need to generate an additional replication agreement between PSC1. and PSC4. Therefore, if a change is made on PSC1, it is not replicated on PSC3 or PSC4: otherwise, you can check the replication status of a psC with the vcdrepadmin-f showpartners command. Each PSC must have 2 replication partners. From the output, we also find the current synchronization with the entire replication partner with the value curren update sequence number (USN) and, In case of error, check the protocol /var/log/vmware/vmdird/vmdird/vmdird-syslog.log VDCREPADPADMIN showpartnerstatus is to display the current PSC replication partner and also the current replica status between the two nodes. You can see that we now have two agreements. Rinse and repeat on PSC2 PSC4 and we have the VVD topology. In this example, note that I did everything from PSC1, while I refer to different PSC files: You now have your replication agreements. As for the vdcrepadmin command, you have the following options The charge compensation has no influence on the configuration of the ring topology. You need to set it up if you want to replication between PSCs. Load Balancer is placed on each website before the 2 PSCs and the vCenter Server (s) tab on the Loadr VIP address. This procedure is also available for PSC races on a Windows computer.
For more information, see KB 2127057. This kb article also contains additional commands of vcrdepadmin tools as well as a procedure for removing a replication partner from a PSC. ./vdcrepadmin -f createagrement -2 -h psc3.griffiths.local -u Administrator -H psc1.griffiths.local If we have more PSC, then plan to have the topology of the network and with the createagrement, we can plan the same. Due to the replication time, it can take a few seconds to minutes for a complete network topology to be configured. If PSC2 dies, replication continues. By connecting PSC1 to PSC4, the full ring is created. This does not happen by default. We will follow the steps to create this. Step 8 under the creation of the ring chord has a typo, it should be “psc04.contoso.com” instead of “psc03.contoso.com”.
Please correct him. The document is quite edifying and informative. Thank you very much..!! As noted above, this facility will create a redundant PSC topology, as all PSPs will be replicated with the neighbor offering redundancy. However, the replication between the last and the first PSC must be created manually to achieve this configuration. Use this command to show the current status of the PSC replication and its partner nodes: vdcrepadmin -f removeagreement -2 -h Source_PSC_FQDN -H PSC_FQDN_to_Remove_from_Replication -u administrator -w Administrator_Password Before you execute the agreement, check the current partner. Add an agreement with psc3.griffiths.local with the following command: If PSC-01 is provided and configured, provide PSC-02, PSC-03, etc. It is important to do this one after the other and register for the previous CSP when the next one is provided. So if you provide PSC-02, save it to PSC-01 during installation.
