Recovery Procedures
•
Review the guidelines provided in Section 10, “Contingency Planning.” Having a
disaster recovery plan in place can help you and your staff recover from a disaster as
quickly as possible, with minimal damage to your system and data.
•
Document recovery procedures and make them available to operations and support
staff. Information on how to determine the cause of a problem should also be
documented and available.
•
Assign the responsibility for carrying out the recovery procedures to the appropriate
people.
•
Make sure that full copies of all manuals are available in the operations area,
including all relevant application user manuals.
•
Provide documentation describing all major system components, their
configurations, and how they deliver services. Include an SCF LISTDEV of the
system in its “normal” state and examples of system and network diagrams.
•
Ensure that a terminal and telephone are situated in the computer room next to the
system so that an operator can discuss the problem on the phone while accessing
information in the computer room.
•
Make sure that backup tapes are available and readable to ensure that files can be
restored.
•
In an environment without NonStop TM/MP, document all files that are updated
online. Document the location, size, type, contents, and importance of each file, and
the recovery options.
•
Test the recovery procedures to ensure that they work and are as simple to use as
possible.
•
Train your staff in the recovery procedures.
•
Ensure that super-group (255,n) capabilities are available under special conditions.
Although a super-group logon is not needed under normal conditions, it might be
required to solve certain problems.
•
Require surprise drills to ensure that your staff can perform the recovery procedures.
•
For serious failures, such as hardware, processor, system, and power failures, you
should notify your Tandem representative in addition to following your internal
escalation procedures.
