An Ops Center user was recently planning a deployment, and they were wondering about disaster recovery. Apart from Ops Center's High Availability option, they asked, what recovery options are available if an EC system completely dies?
One other option that you can use is Ops Center's backup and restore capability. If you've made a backup of your Enterprise Controller, it's possible to restore that Enterprise Controller on a new system. There are a few tricks with doing so, though:
- The new system has to have the same version of Ops Center, including all upgrades and IDRs.
- If the IP address of the new system is different, you have to manually change the Proxy Controllers to point to the new IP.
- Ops Center libraries are not part of the backup, so if they're on nfs storage, they need to be accessible to the new system as well.
- The /var/opt/sun/xvm/images/os directory, containing OS images, needs to be backed up and restored separately, because it's big.
The Backup and Restore chapter explains how to restore the Enterprise Controller on a new system.
