How to achieve high availability in VCSA 6.5 has always been a concern of everyone. VCSA 6.5 version provides HA configuration, which is commonly known as active-active (the actual switching will be interrupted). This article will introduce how to configure active-active in VCSA 6.5 .
1. Preparation
1. Install and configure the VCSA 6.5 virtual machine;
2. Prepare three ESXi hosts, create 2 VCSA virtual machines ( peer and witness ) and generate virtual machine running rules during the HA configuration process ( 3 VCSA virtual machines must run on different hosts);
3. Network for VCSA HA ;
2. VCSA HA configuration
Step 1 , Configure vCenter HA .
Step 2 , select the basic configuration option.
Step 3 , add a network adapter for VCSA .
Step 4 , configure the passive node IP address.
Step 5 , passive node IP settings.
Step 6 , Witness node IP configuration.
Step 7 : Confirm the configuration of the passive node and the witness node. If there is a warning prompt, please check.
Step 8 , confirm the content of the compatibility problem.
Step 9 , adjust compatibility issues by editing.
Step 10 , confirm the configuration.
Step 11 , start cloning the peer virtual machine.
Step 12 , the peer virtual machine is cloned successfully and powered on.
Step 13 , clone the witness virtual machine.
Step 14 , the witness virtual machine is cloned successfully and powered on.
Step 15 : Automatically configure virtual machine running rules.
In step 16 , the system continues to deploy HA .
Step 17 , VCSA HA is successfully deployed.
Step 18 , view HA monitoring.
Step 19 , start the HA switch.
Step 20. After the HA switch is started , the VCSA virtual machine will be interrupted. Pay special attention that the time is not a few seconds, but a few minutes.
In step 21 , the WEB CLIENT client will be disconnected.
Step 22 , after the switch is successful, the VCSA can be accessed again.
