corresponding ‘standby server’ in Site B. For example:
EXC1 -> EXC04 EXC2 -> EXC05 EXC3 -> EXC06
The Exchange Servers in Site B will take ownership/responsibility of serving all corporate messaging requirements and provide users with access to all mailbox data with no data loss.
- AD attributes such as HOMEMDB and HOMEMATA will become incorrect. The following process details the steps required:
1. Site A goes down.
2. Open up ADU&C and use the multiple select options to select each of the mail-enabled user objects that were homed on Exchange Servers.
3. Right Click the combined group selection and choose Exchange Tasks. The Exchange Task Wizard will launch. Follow through the wizard to
delete each of the mail-enabled user objects mailboxes.
NOTE: Pre-defined LDAP queries (querying the AD for HOMEMDB and HOMEMTA) can be created and saved into the ADU&C MMC. This will
facilitate the quick identification of users homed on the failed servers.
4. Move the DB's as planned. (Storage level – executed by the presentation of target LUNS).
5. Mount appropriate databases within the RECOVERY MAILBOX CENTER (RMC).
6. Using the RMC select all non-connected mailboxes using either the CTL or Shift Key.
7. Right click and select FIND MATCH. Matching wizard will launch and establish GUID matches for each deleted MBX for an active user account.
8. Right click the group selection for a second time and choose the RECONNECT option.
9. The Mailbox connection feature will reconnect each of the deleted mailboxes with their original user account thus updating the HOME_MDB and
HOME_MTA attributes with the new ‘dead server’ name where the mailbox will now be homed.
10. Change the MAPI profile via network script/PROFMAN tools.
