Recovering the Exchange 2007 storage group to the point of failure


Recovering the Exchange 2007 storage group to the point of failure
Prev	Scenario III: Some DB volumes missing, transaction logs are available	Next

Use the following procedure to recover the Exchange 2007 storage group to the point of failure (POF).

Note:

When restoring after hardware failure, you must use the command line and make sure to specify the -r option.

Warning:

You must dismount all databases (stores) in the affected storage group before issuing the command. You must also verify that you have correctly assigned the drive letter or mount point to each volume and that you have accounted for all the volumes in the storage group (component).

To recover the storage group to the point of failure from the command line

Verify that all databases (stores) in the affected Exchange storage group are dismounted.
Verify that you have correctly assigned the drive letter or mount point to each volume and that you have accounted for all the volumes in the storage group (component).
Close the Exchange GUI and all Explorer windows, applications, consoles, or third-party system management tools that may be accessing the volumes.
Type the command as in the following example, which recovers the storage group associated with the TestDB.xml metadata file:
```
vxsnap -x TestDB.xml -r restore restoreType=POF
writer="Microsoft Exchange Writer"
```
If only one database volume is missing, you can perform a single database restore by using the subComponent=subComponentName option in the vxsnap restore command. For example, if DB1 is the name of the Exchange database that is associated with the volume SG2-DB1, type the command:
```
> vxsnap -x TestDB.xml -r restore restoreType=POF
    subComponent=DB1 writer="Microsoft Exchange Writer"
```
Use Exchange to mount all databases (stores) in the Exchange storage group; the transaction logs will roll forward to the point of failure.
This action can be observed in the Event Viewer Application log.
