Hi Folks
I am working on developing installation instructions for EV in High Availibility scenario. If any of you have done this sort of installation anywhere can you please verify?
Production Site : 1 EV Server, 1 DA(Discovery Accelerator) Server, 1 SQL Server, Storage on SAN
DR Site: 1 EV Server, 1 DA(Discovery Accelerator) Server, 1 SQL Server(Replicated from Production SQL using log shipping) , Storage on SAN (Replicated from production SAN using VVR)
Installation Procedure
1. Configure SAN Data replication using VVR
2. Install & Configure EV & DA in prod environment.
3. Configure SQL Replication
4. Stop EV & DA Services in production
5. Stop SAN replication
6. Change SQL, EV & DA DNS aliases to DR Site
7. Bring up SQL in DR environment from log shipping
8. Install EV in DR site, but do not run configuration wizard.
9. Open EV Console and point to existing Directory, all the configuration is present and EV ready to execute.
10. DA must NOT present Config option, instead is ready for use.
Above is very high level installation steps that should be followed. What I am looking for is any flaws in this technique. I have been through HA & Building block recommendation from symantec but it always assumes there is 1 SAN & 1 SQL shared by both the site. Which is completely different to what we are trying to achieve.
Can any of you EV gurus please verify and recommend any changes to these steps if needed?
Appreciate your help.
