Before starting the Exchange server backup, make the following preparations:
Register the hardware provider
Configure the Exchange server environment
Set up the AdvancedCopy Manager cluster
Prepare a drive letter map file
Set up the source and replica volumes
Register the hardware provider copy set
Save the hardware provider management file
Create a device definition file
Save the device definition file
Register database information
On both the Exchange server and the backup server, execute eternus_provider (Provider registration/deletion command) to register the ETERNUS hardware provider. Perform this operation with the Exchange server on all nodes that make up the cluster group.
Set up the Exchange server based on the results of the backup design.
Applying the Service Pack
This function supports Exchange server 2003 or Exchange Server 2007.
For Exchange Server 2003, Service Pack 1 and Service Pack 2 are supported. You should apply Service Pack 1 or Service Pack 2 if it has not been applied.
Allocating EDB, STM, CHK, and LOG files
Allocate the Exchange server EDB, STM, CHK, and LOG files.
Refer to "8.1.2.2 Designing storage groups" for details.
Installing Exchange system management tools
Be sure to install the Exchange server system management tools on the backup server. For Exchange Server 2003, apply Service Pack 1 or Service Pack 2 (the service pack level on the backup server must be the same as the Exchange Server).
If the Exchange Server has a cluster configuration, customize the Storage Server transactions at the Exchange Server.
Refer to the following manuals for transaction details:
ETERNUS SF AdvancedCopy Manager Operator's Guide for cluster environment
The drive letter map file defines the drive letters (or mount points) to be assigned to the shadow copies (ie, backup volumes).
Create a drive letter map file with the following file name on the backup server:
Configuration settings directory\etc\repl\data\EXDMAP.INI |
An example of the settings in the drive letter map file is shown below.
[DRVMAP] g1d1p1=F: g1d2p1=C:\mnt |
During backup processing, a drive letter is assigned to a backup volume based on the settings in the drive letter map file.
The drive letter assignment is not performed if there is no drive letter defined in the drive letter map file, or if the file contains a setting error (e.g., the relevant drive letter is in use, or an invalid directory is specified for a mount point, etc.)
Complete the following additional steps when performing the operations explained in "7.4 Preparations":
Register all the transaction volumes (those to which files with *.edb, *.stm, *.log, and *.chk extensions are allocated) and their backup volumes as replica volumes.
Set the transaction volumes as source volumes and the backup volumes as replica volumes. (Do not reverse the source and replica volumes.)
Set the Exchange server (the source volume server) as an operation server (by specifying "ORG" or "BOTH" as an argument of the -o option in the replication volume information configuration command (swsrpsetvol)).
Do not specify the -u option because the restoration needs to be performed.
Use the partition unit (gXdYpZ) as the volume registration unit. Do not register using the LUN unit (gXdY).
Execute the copy set registration command on the Exchange server to register the relationship between transaction disks and backup disks. Execute the command in the primary node making up the cluster group.
Example:
C:\>C:\Win32app\AdvancedCopyManager\bin\eternus_copyset -set -o g1d1@ EXCHG-SVR -t g1d11@BKUP-SVR -c QOPC -g BK1 eternus_copyset set successfully completed. C:\> |
Save the hardware provider management files in case of emergency. The files to be saved are as follows:
AdvancedCopy Manager shared-data shared-disk drive:\etc\opt\swstorage\etc\prov_copyset.ini
Configuration settings directory\etc\prov_copyset.ini
Create a device definition file on the backup server according to the following procedure:
Confirm the OLU number and physical device number of the copy destination device.
Execute the (eternus_getolu) command to confirm the OLU number and physical device number of the copy destination device.
Refer to eternus_getolu (Source disk number display command) for information on this command.
Confirm the device instance IDs of all copy destination devices.
Confirm the device instance IDs as follows:
Start Computer Management.
Select [Start] -> [Management Tool] -> [Computer Management].
Select [Disk Management] from [Computer Management] to display the properties of the device subject to a backup. Confirm the location (Bus Number, Target ID, LUN).
From [Computer Management], select [Device Manager] -> [Disk Drive] to display the disk drives.
Select Disk Device (such as FUJITSU GR740 SCSI Disk Device) from [Disk Drive] to confirm the device subject to a backup.
Select Disk Device (such as FUJITSU GR740 SCSI Disk Device) and right-click, and then select Properties. Confirm that the Disk Device for which the location (Bus Number, Target ID, LUN) confirmed in b) of Step 2 matches the location (Bus Number, Target ID, LUN) indicated in the displayed Properties.
When the location that was confirmed in b) of Step 2 matches a location confirmed in d) of Step 2, select Detail to confirm the device instance ID.
Save the combination of the physical disk number and the device instance ID confirmed in point e) of Step 2 to a text file.
The device instance ID can be displayed by executing the eternus_getins command.
Refer to eternus_getins (device instance ID display command) for information on this command.
Create a device definition file.
Create a device definition file using a combination of the destination device OLU number confirmed in Step 1 and the device instance ID confirmed in Step 2.
Name the following device definition file with notepad:
AdvancedCopy Manager configuration settings directory\etc\eternus_hardope.def |
Enter the combination of OLU number and the device instance ID in one line in the format below.
OLU number, device instance ID <Enter> |
Example:
149,MPIO\DISK&VEN_FUJITSU&PROD_E4000&REV_0000\1&7F6AC24&0&4534353053323041232323232020202020203641303030303330333033390000 150,MPIO\DISK&VEN_FUJITSU&PROD_E4000&REV_0000\1&7F6AC24&0&4534353053323041232323232020202020203641303030303330333033390001 151,MPIO\DISK&VEN_FUJITSU&PROD_E4000&REV_0000\1&7F6AC24&0&4534353053323041232323232020202020203641303030303330333033390002 152,MPIO\DISK&VEN_FUJITSU&PROD_E4000&REV_0000\1&7F6AC24&0&4534353053323041232323232020202020203641303030303330333033390003 |
To ensure that this file is not lost, save the device definition file of the backup server.
Save the following file:
AdvancedCopy Manager configuration settings directory \etc\eternus_hardope.def |
Register Exchange server database information in the management file using swsrpdbinfo_ex2k3/swsrpdbinfo_exchange (Exchange database information registration command). Before backing up or restoring the Exchange server databases, execute this command on the Exchange server to perform an initialization. Additionally, execute this command after any change has been made to the Exchange server configuration.
Example: This example stores the database information of the storage group FirstStorageGroup. Execute the command from the business server (EXCHG-SVR).
C:\>set SWSTGNODE=nodeAGT C:\>C:\Win32App\AdvancedCopyManager\bin\swsrpdbinfo_ex2k3 -evs VSVR -sgname FirstStorageGroup swsrpdbinfo_ex2k3 successfully completed C:\> |
If the Exchange Server has a single configuration, an AdvancedCopy control disk (access path) must be created for the Exchange Server.
This section is not required for cluster configurations because the shared disk for AdvancedCopy Manager shared data is used as the access path.
The following table shows the procedures for creating an AdvancedCopy Manager control disk.
No | Procedure | Tasks |
|---|---|---|
1 | Create a logical unit | Create a logical unit in the same disk array as the backup target Exchange database. The logical unit can be any size. (Since the AdvancedCopy control disk does not depend on the size of the disk, it can be created with the minimum size.) |
2 | Connect to host | Connect the created logical unit to the host. Refer to the ETERNUS disk array manual for the connection procedure. |
3 | Create partitions | Create a partition in the logical unit (disk) that has been connected to the host (server). |
4 | Assign a drive letter | Assign a drive letter to the partition created in Step 3. * A mount point cannot be used instead of a drive letter. |
5 | Create a file system | Format the partition created in Step 3 as NTFS. |
After the AdvancedCopy control disk is created, create a new access path definition file under the following filename on the Exchange Server:
<ACM configuration settings directory>\etc\eternus_accdrv.ini |
he format for the access path definition file is as follows:
Drive=<drive letter> |
The following example show an access path definition file entry (if the drive letter is E):
Drive=E |
