6. When completed with DR testing, click the continue link in the Recovery Steps tab. SRM will bring down
the DR test environment, disconnect the LUN, clean up the FlexClone volume, and return the
environment to normal.
7. If you cloned an Active Directory/DNS server at the DR site it can now be shut down, removed from
inventory, and deleted. A new clone should be created if re-running DR tests after some time, as the
windows security information in the AD server may become outdated if not updated periodically. Again,
ensure that the cloned AD server is never connected to a public VM Network.
8 EXECUTING RECOVERY PLAN: TRUE DR SCENARIO
8.1 REQUIREMENTS AND ASSUMPTIONS
Every environment has its own unique characteristics; each environment can have an effect on a DR plan.
Depending on the type of DR solutions deployed, each organization’s DR situation could be very different.
To make sure of success, you require proper planning, documentation, and a realistic walkthrough of a DR
scenario.
To provide a successful DR experience, consider some general requirements and assumptions. This is not
an all-inclusive list. There are many variables to plan for depending on the configuration of each
environment.
• The SRM on NetApp environment has been set up properly, and all SRM recovery plans have been
tested successfully.
• During recovery plan testing, the functionality of the environment was verified.
• Systems administrators have access to a workstation or server desktop session from which to
administer the DR site and perform the failover.
• Systems administrators have all appropriate credentials, accounts, passwords, and so on required to
access the systems.
• Connectivity to the DR network is available from where every operations will be performed.
• Certain infrastructure servers already exist in the DR site and are accessible. These systems provide
basic services necessary for the administrators to work in the environment and execute the recovery
plan.
- The DR site vCenter and SRM servers.
- DR site Active Directory services.
- DR site DNS services.
