9 2 Prerequisites 2 Prerequisites 2.1 Introduction The prerequisites are listed in detail in the following subsections. Please study this document carefully in order to be best prepared for a disaster recovery situation. Note: The recovery process for SafeCom master server and SQL master server is dependent on ready-available license key code (2.4) and password (2.5) and requires the following: Purchase of SafeCom DR License, Enterprise (p/n ) or SafeCom DR License (p/n ). Communicating with license@safecom.eu to get the Form worksheet in the safecom_g2_disaster_recovery_form_60614.xls file completed. 2.2 Store files in network folder Quite a few of the prerequisites involve access to certain files. It is recommended to decide on a network folder for these files so they are easy to access in the recovery situation. Folder: 2.3 Record SafeCom solution information Chapter 9 Administrator s installation notes contain forms that allow you to record relevant information about the SafeCom solution, such as version info, IP addresses, SQL instance names etc. Please make sure that these forms are completed and available. D

10 2 Prerequisites 2.4 SafeCom license key code Because the SafeCom license key is linked to the computer name of the SafeCom master server a new license key must be obtained from SafeCom and installed. Special agreement must be made with SafeCom in order to acquire an extra SafeCom license key for recovery purpose. On a cluster server it needs to be the Cluster Name (2.6) instead of the Computer Name. License key code for SafeCom recovery master server. Example: safecom_g2_disaster_recovery_form_60614.xls Used in section License key code that allows an extra SafeCom Additional Server. Example: safecom_g2_disaster_recovery_form_60614.xls Used in section and Figure 1 The safecom_g2_disaster_recovery_form_60614.xls, page 1 D

11 2 Prerequisites 2.5 SafeCom server SQL passwords In the event that the SQL master is lost it is necessary to specify password for each SQL safecom user running on the SafeCom master and slave servers. Special agreement must be made with SafeCom in order to acquire these passwords. SQL safecom user passwords. On a cluster server it needs to be the Cluster Name (2.6) instead of the Computer Name. Example: safecom_g2_disaster_recovery_form_60614.xls Used in section 3.2.5, and Figure 2 The safecom_g2_disaster_recovery_form_60614.xls, page Determine the Cluster Name The cluster name is only relevant for the servers where the SafeCom is running. It is not relevant for SQL servers without SafeCom. It is typically only SafeCom slave servers that are clustered. 1. Open Cluster Administrator. 2. Browse to Groups, Cluster Group. 3. Right-click Cluster Name and select Properties. 4. Click on the Parameters tab. 5. Name contains the cluster name. D

12 2 Prerequisites 2.7 Domain user There is a domain user that is a member of the local administrator group on each server that is part of the SafeCom solution. The user account is used to execute SQL scripts on the SafeCom servers. 2.8 SafeCom G2 Server software installation files The SafeCom G2 server software MUST be the same version on all the SafeCom servers in the solution. Example: S *05. Make sure to have a copy of the software around in case it needs to be installed in preparation for the recovery (recommended) or during the recovery process. Ensure that any patches are available as well. SafeCom G2 Server software installation files. Example: exe or safecom_g2_380_04.exe 2.9 SQL scripts and command files The below SQL scripts and command files are required in the recovery process: new_master_server.sql and new_master_server.cmd This SQL script updates the SafeCom databases to reference the SafeCom recovery master server. The script can be executed by running the SafeCom supplied command file new_master_server.cmd on the SafeCom recovery master server. Used in section break_mirror.sql and break_mirror.cmd This SQL script breaks the mirror. Used in section remove_db_replication.sql and remove_db_replication.cmd This SQL script removes the replication on the SafeCom slave servers so they are ready to become part of the replication from the SQL recovery master server. Used in section and move_to_server.sql and move_to_server.cmd This SQL script moves users and devices from one server to another. Used in section D

13 2 Prerequisites 2.10 Backup of SafeCom database A backup exists of the SafeCom databases so this can be restored on the SQL recovery master server. The databases should be backed up regularly.

33 5 SQL master server 5 SQL master server 5.1 Introduction This chapter describes the steps necessary to switch to an SQL recovery master server, SU-SQL-2. Servers involved: SafeCom master server, SU-M-1. SQL master server, SU-SQL-1, and SQL recovery master server, SU-SQL-2. In order to create the replication in an as simple as possible manner the recovery process involves adding (and removing) an additional SafeCom recovery slave server, SU-S-2. Preparation: Prepare the additional SafeCom recovery slave server, SU-S-2, in advance with correct firewall configuration (6.2.1) and SafeCom G2 server software (6.2.2). This will save time in the recovery process. Interruption: Interruption to administration will occur during most of the recovery process. There is no interruption to printing during this process (assuming all printing is handled by the SafeCom slaves and not by the SafeCom master server). D
