Recommendations
When Cisco Prime Network Registrar is deployed on virtual machines, review the following recommendations:
•
Do NOT deploy HA DNS or DHCP failover partners on the same physical server (in separate VMs).
This will not provide high availability when the server goes down. Ideally, the high available/failover
partners should be sufficiently "separate" that when one fails (because of a hardware, power, networking
failure), the other does not.
•
When deploying multiple CPNR VMs on the same physical server (or servers served by a common set
of disk resources), you should stagger the automatic nightly shadow backups (by default, they occur at
23:45 in the server's local time). To know how to alter this time, see the
"Setting Automatic Backup
Time" section in Cisco Prime Network Registrar 9.1 Administrator Guide
.
It may be acceptable to not follow the above recommendations for lab environments; but they must be
followed for production.
