Redpaper Alex Osuna Bert Jonker Richard Waal Henk Vonk Peter Beijer Disaster Recovery Procedures for Microsoft SQL 2000 and 2005 using N series Introduction This IBM Redpaper gives a example of procedures to restore the Microsoft SQL 2000 and 2005 using SnapManager.There are options discussed that depend on the type of disaster, the type of data recovery, and the type of system on which the disaster applies. Our environment The environment used in creating this paper is: SQL 2005 2x IBM Xseries 3850 in a SQL 2005 cluster Broadcom onboard for cluster heartbeat 2x Intel PCI dual port 1 GB Ethernet adapter.

In the SnapManager Administration guide several restore options are described, followed by a step-by-step instruction. This paper does not describe those steps. 2 Disaster Recovery Procedures for Microsoft SQL 2000 and 2005 using N series
Restoring a snapshot with SnapManager In this section we discuss the steps taken in a test scenario as executed during a disaster recovery test. Log on to the SQL server (in this case SQL2000 PDC1DB005) with SA_snapdrive and start Enterprise Manager for SQL. 1. Select properties of the database that you want to restore (Figure 1). Figure 1 Database properties Disaster Recovery Procedures for Microsoft SQL 2000 and 2005 using N series 3
2. Set the database in single user mode (Figure 2). Figure 2 Single user mode 3. Close Enterprise Manager. 4 Disaster Recovery Procedures for Microsoft SQL 2000 and 2005 using N series
4. Stop the (remote) services that connect to the database. Use the process information of SQL Enterprise Manager to find active processes (Figure 3). Figure 3 Find active processes 5. Start SnapManager for SQL. Depending on what database you must restore (and the sort of backups taken for that database), the procedure may differ.

6. Connect to the SQL instance on which you want to perform a restore (Figure 4). Figure 4 Connect to SQL Server 6 Disaster Recovery Procedures for Microsoft SQL 2000 and 2005 using N series
Figure 5 Connecting to SQL server 7. The backups should be verified (this is part of the full backup run at 2 a.m.). If you receive a message that the backup is not verified, you can start a separate verification job, run it as a part of the restore job, or restore an unverified database. See the SnapManager Administration guide for more information. Disaster Recovery Procedures for Microsoft SQL 2000 and 2005 using N series 7
8. Open the Restore tab and check the verification server. This should read pdc2db005\pdc2db005 on the SQL 2000 cluster and pdc2db002\pdc2db002 on the SQL 2005 cluster. Figure 6 Checking the verification server Now open the database to be restored. There are two methods of doing this using step 9 or step 10 depending on the kind of backup taken. 8 Disaster Recovery Procedures for Microsoft SQL 2000 and 2005 using N series
9. At this point you can click the database, as shown in Figure 7, and proceed to step 11. Figure 7 Selecting the databases Disaster Recovery Procedures for Microsoft SQL 2000 and 2005 using N series 9
10.Or you can double-click the disks that are holding the databases, as shown in Figure 8. In our case we selected all the databases on that disks and scrolled through the window to select the required databases. Figure 8 Selecting the disks that hold the database 10 Disaster Recovery Procedures for Microsoft SQL 2000 and 2005 using N series
11.Select the backup that you want to restore by double-clicking the full backup that you want to be restored (Figure 9 and Figure 10). Figure 9 Selecting backup to be restored Figure 10 After selection Disaster Recovery Procedures for Microsoft SQL 2000 and 2005 using N series 11
12.In right part of the window shown in Figure 11 you can see which logs you want to be restored with the full backup. Keep in mind that if you restore all the logs you will go to the last status known (Figure 11). It may be that you want to restore to the point in time of the last backup and not want the last change of the day restored. In that case deselect all the logs (Figure 13 on page 13).
