Restoring an SQL Server database to a primary volume
This section provides an example of recovering an SQL Server database when the backup data is
stored on the secondary volume. This example restores the data from the secondary volume to the
primary volume by resynchronizing the volumes. The operation ID is
Operation_A .
Restoring an SQL Server database
To restore the SQL Server database:
1. Check the backup ID of the backup you want to use for restoration.
Check the backup ID of the backup data to be used for restoring. To check the backup ID, execute
the
drmsqlcat command on the database server. Here, the predetermined instance (default)
is used as the instance name of SQL Server.
DBServer >drmsqlcat default
INSTANCE: default
BACKUP-ID: 0000000001 BACKUP-MODE: ONLINE INSTANCE: default ORIGINAL-ID: 0000000001
START-TIME:2002/06/01 10:00:00 END-TIME: 2002/06/01 10:03:00 HOSTNAME: DBServer
T DB OBJECT FILE FS DG DEVICE COPY-GROUP
M DB1 METAFILE D:\MSSQL\DBServer\INSTANCE_1\META D: - - -
D DB1 DATAFILE E:\SQL\data1 E: - Harddisk1 VG01,sqlvol01
T DB1 TRANSACT E:\SQL\tlog E: - Harddisk2 VG01,sqlvol01
:
If you perform restoration in units of instances, including a specific database, by executing the
restoration command with the
-target option specified, check the restoration target.
2. Create a backup ID file.
To create a backup ID file, execute EX_DRM_BACKUPID_SET with the backup ID.
DBServer > EX_DRM_BACKUPID_SET Operation_A -backup_id 0000000001
3. Restore the data from the secondary volume to the primary volume.
Restore the data by resynchronizing the primary and secondary volumes. To restore the data,
execute
EX_DRM_SQL_RESTORE
on the database server.
DBServer > EX_DRM_SQL_RESTORE Operation_A -resync
When EX_DRM_SQL_RESTORE is executed with the -undo option specified, restoration is
performed while the database is in the standby status, in which the database is read-only. If the
-undo option is omitted, after restoration, the status of the database changes to loading, and
the database cannot be viewed. Note that the -undo option cannot be used unless the UNDO
file storage directory has been set using the drmsqlinit command.
Also, do not connect to SQL Server while executing EX_DRM_SQL_RESTORE .
4. Recover the SQL Server database.
To recover the SQL Server database, execute the drmsqlrecover or drmsqlrecovertool
command on the database server.
The following shows an example of the drmsqlrecover command and drmsqlrecovertool
dialog box. For details on the drmsqlrecover command or the drmsqlrecovertool dialog box,
see the HP P9000 Replication Manager Software Application Agent CLI Reference Guide.
