During a DNS or Move IP redirection, the Security Principal Names (SPN) are moved from the Master server to the Replica server. The following list shows the SPNs on an example server named Exchange PRD1, on domain XOlab.com:
|
SPN |
Example SPN |
|
ExchangeMDB/<Master FQDN> |
ExchangeMDB/ExchangePRD1.XOlab.ca.com |
|
ExchangeMDB/<Master NetBios> |
ExchangeMDB/ExchangePRD1 |
|
ExchangeRFR/<Master FQDN> |
ExchangeRFR/ExchangePRD1.XOlab.com |
|
ExchangeRFR/<Master NetBios> |
ExchangeRFR/ExchangePRD1 |
|
SMTPSVC/<Master FQDN> |
SMTPSVC/ExchangeRPD1.XOlab.com |
|
SMTPSVC/<Master NetBios> |
SMTPSVC/ExchangePRD1 |
The Security Principal Names are found on the Computer Object in the Active Directory. When a switchover occurs, Arcserve RHA removes these SPNs from the Master server's Computer Object and adds them to the Replica server's Computer Object. When the Replica server is active, you can see SPNs for both Master and Replica servers on the Replica server's Computer Object.
If a Replica server is called ExchangeDR1 in the same XOlab.com domain, and this Replica is active, the following SPNs are listed in the Replica's Computer Object:
