9.

After the file copy restore completes and the database files are successfully recovered, you
can remount the database to continue its operation.

If performing the restore in a DAG environment, reseed the database replication if necessary.

10. (For Exchange 2007) If you are performing the restore in a CCR environment, reseed the

remote database using the Update-StorageGroupCopy command from the Exchange
Management Shell. In some cases, you may need to use Resume-StorageGroupCopy to
resume the replication.

Volume Promote Point-In-Time Recovery

To perform a volume promote point-in-time recovery:
1.

Make sure the virtual copy you would like to promote has a status of Available. If it is Mounted,
unmount it.

2.

Execute the volume promote restore command from the Recovery Manager for Exchange
backup server.

(For Exchange 2007) For single copy cluster volume promote restores (not CCR), the following
extra steps need to be performed:
1.

All of the resources the storage group uses, including the disk(s) for the storage group’s Log
path, System path, and its mailbox(es)’ database(s), need to be put in extended maintenance
mode.

2.

From the command line, issue the following command for all disks the storage group uses:

cluster res "resourcename" /maint:on

cluster res "resourcename" /waitmaint

3.

From the Cluster Administrator, take the Disk(s) offline.

4.

From the backup server, execute the Recovery Manager command for the volume promote
restore. For information about the restore-promote command, see

“Using the Recovery Manager

CLI” (page 57)

. For information on using the GUI to execute a volume restore, see

“Restoring

from a Virtual Copy” (page 53)

.

WARNING!

DO NOT perform a volume promote restore if multiple storage groups share

any volumes. This includes all data files .LOG, .EDB, and .CHK. If you are not sure how or
if your storage groups share volumes, execute the script chk_multi_storage.cmd by
default installed at Program Files/3PAR/RM/Exchange/bin.

5.

In the Computer Management window, for volume promote restores, right-click the Disk
Management node and select Rescan Disks.

6.

From the Cluster Administrator, bring the Disk(s) back online.

7.

Follow the appropriate steps depending on whether you are performing the operation for

“Single Copy Clusters” (page 98)

or

“Continuous Copy Replication Clusters” (page 99)

Single Copy Clusters

1.

For the disk(s) previously put in maintenance mode, take ALL of them out of maintenance mode.

2.

From the command line, issue the following command for all disks the storage group uses:

Cluster res "resourcename" /maint:off

3.

Verify the EDB, LOG, CHK files are correctly appearing in the original database locations.

4.

Mount the databases within the storage group.

The database is recovered to the point-in-time when the virtual copy was taken.
