In this example of configuring IT Advisor disaster recovery, two stand alone servers have been created, Server1 and Server2. Server2 will be configured as the disaster recovery node to Server1.
IMPORTANT: If the Disaster Recovery node is monitored by Data Center Expert via SNMP, it is important to set the device scan timeout in DCE high enough for the Disaster Recovery node to respond. Otherwise, it will return a communication lost status. How you set the device scan timeout depends on the network speed between the Disaster Recovery node and the ITA server.
Log in to the Server1 Webmin interface, and select EcoStruxure IT Advisor > Disaster Recovery.
Select Allow another node to connect to this node.
In Allow the following IP as disaster recovery node, enter the IP address for Server2.
Check Accept fingerprint then click Allow.
Once the fingerprint is added successfully, follow the on-screen instruction to go to Webmin for Server2 to continue the setup.
Go to Server2, Webmin interface > IT Advisor > Disaster Recovery.
- Select Attach this node (xx.xx.xx.xx) as a disaster recovery node to another node/cluster.
- Enter the IP address for Server1 in Attach this node to the following IP:
- Click Attach.
Check Accept fingerprint. and then click Attach.
While the node is successfully being attaching, the notification is Attaching the node, please wait this could take several minutes......
Please watch the status page to monitor progress.
The Server1 Status page displays information for both itself and Server2 as Disaster Recovery.
The Server2 Status page displays information only about itself as Disaster Recovery.
Upgrading a disaster recovery setup
Upgrade both the master node and the disaster recovery node to the new version of IT Advisor.
