Selecting the appropriate recovery strategy

Use this information to determine the correct procedure for recovering your system.

Before beginning your recovery, you must perform these tasks.

• Make sure you understand what has caused the problem. Understanding the cause helps you choose the correct recovery steps.
• Plan your recovery. Use Table 1 in the Choosing the recovery procedure for a disk failure or disk errors topic to find the appropriate recovery checklist for your situation.
• Make a copy of the checklist and check off each step as you complete it.
• Keep the checklist for future reference.
• Keep a record of what you have already done and what you do for the rest of your recovery. This record is important if you need help later.
• If your problem requires hardware or software service, make sure that you understand what the service representative did. Do not be afraid to ask questions, such as:
  • Was a disk unit replaced? If yes, which one?
  • Was the Licensed Internal Code restored? If yes, what option from the Install Licensed Internal Code (LIC) menu was used?
  • Did the disk configuration need to be recovered? Was it successful?
  • Can the failed disk unit be pumped? How successfully?
