After SCR Activation - What Next?
Posted by ~Ray @ 2008-03-15 23:17:26
After watching my on Standby Continuous Replication (SCR) in Exchange Server 2007 Service Pack 1 (SP1) several viewers have written to ask for instructions on how to resume production activity on the original database.
To recap at the end of the SCR video the SCR target copy was activated using database portability. On the original Mailbox server (E2K7) the original production database (MBX1) was left dismounted in its original storage group (SG1) and all users from MBX1 were now being serviced by a database called MBX1PORT in a storage group called SG1PORT1 on a Mailbox server called E2K7DR. Click for a screen shot illustrating this configuration.
Once user mailboxes have been rehomed to the activated SCR aim database on E2K7DR the final steps involve cleanup work on E2K7 creating a new database on E2K7 and then re-homing all of mailboxes from MBX1turn on E2K7DR to a new mailbox database on E2K7. To do this you would:
You can dismount MBX1PORT and use database portability to re-home the users in Active Directory and then manually copy MBX1PORT to the folder containing the database created in Step 5 above (including renaming MBX1PORT. EDB to MBX1. EDB). The dominate you would use to re-home the mailboxes is very similar to the command used to move the users to the SCR target database. The only difference is you are now going the other way: Get-Mailbox -Database e2k7dr\sg1port\mbx1turn |where {$_. ObjectClass -NotMatch '(SystemAttendantMailbox|ExOleDbSystemMailbox)'} | Move-Mailbox -ConfigurationOnly -TargetDatabase e2k7\sg1\mbx1 -Confirm:$False
You could also re-establish SCR for MBX1PORT using E2K7 as the SCR aim computer. Then after the SCR aim database has been created and after you have verified that SCR is active and healthy you can wait until the SCR aim write is up-to-date (e g. it is only behind the appropriate be based on the 50 log file replay delay or any other ReplayLagTime that is configured) and then you can disable SCR and activate the SCR target on E2K7.[ADVERTHERE]Related article:
