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.

Recovering a snapshot with SnapManager for SQL
The process to restore a SQL database requires DBA skills and knowledge of
the SnapManager product. In the SnapManager Administration guide several
restore options are described, followed by a step-by-step instruction. This paper
does not describe those steps.

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).

2. Set the database in single user mode (Figure 2).
Figure 2 Single user mode
3. Close Enterprise Manager.

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).

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.

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.

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.

9. At this point you can click the database, as shown in Figure 7, and proceed to
step 11.

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.

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).

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).

13.When the restore completes do not forget to remove the single user access to
the database.
