Administrator's Guide

If you create a backup copy of the System Recovery DVD using a USB Flash Drive, you can also
use it to restore the system. To create system recovery media using a USB Flash drive, follow the
instructions below.
To create a system recovery USB Flash Drive:
1. Obtain a blank 4 GB or larger USB Flash Drive.
2. Insert the USB Flash device into your workstation or laptop.
3. Open an elevated command prompt with Administrator privileges.
4. At the command prompt, enter diskpart.
5. At the diskpart prompt, enter list disk.
6. Identify the disk number that corresponds to the flash drive. This is typically the last disk listed.
7. Enter sel disk <USB drive number>. For example, sel disk 4.
8. Enter clean. This deletes everything from the USB flash device, so ensure you have the proper
disk selected.
9. Enter create par primary.
10. Enter sel par 1.
11. Enter format fs=fat32 quick.
NOTE: If your USB Flash Drive does not support the FAT32 file system, format the drive as
NTFS instead. Omitting the quick parameter lengthens the format time considerably.
12. Enter active to mark the partition as active.
13. Enter assign letter=<drive letter> to assign a drive letter to the USB drive. For
example, assign letter=U.
14. Enter exit to quit diskpart context commands.
15. Insert the System Recovery DVD into the computer.
16. Using Windows Explorer or a comparable utility, open the DVD so that all contents are visible,
including hidden and system files.
17. Select all of the files (including bootmgr) on the DVD.
18. Copy all of the selected files to the root of the USB drive.
Managing disks after a system restoration
When you restore a system using the System Recovery DVD, the E5000 Configuration Wizard
automatically runs and detects the existence of the data volumes (volumes managed by the P1210m
controller). The wizard remounts the data volumes as appropriate using the mount points in the
C:\ExchangeDatabases directory. For example, the following mount points may be found:
• C:\ExchangeDatabases\Recovery
• C:\ExchangeDatabases\VOL1
• C:\ExchangeDatabases\VOL2
• C:\ExchangeDatabases\VOL3
Restoration in non-production environments
If the E5300 Messaging System was in a non-production environment prior to the system recovery
and the Exchange data does not need to be retained, the data on the appropriate volumes should
be deleted. This includes the mailbox databases and logs found in the mount points listed under
C:\ExchangeDatabases. The HUB transport database and logs (located on the H:\drive) should
also be deleted. The E5000 Exchange Deployment Tool can be used to create a fresh deployment
of Exchange 2010.
