Restore Gotchas

Restore Libraries alphabetically

• Let's suppose you have physical files in one library called GOODSTUFF
• Let's suppose you have logical access to the GOODSTUFF files located in another library called GETGOODIES
• Let's suppose you need to restore several libraries including GOODSTUFF and GETGOODIES
• OS/400 restores libraries in ALPHABETICAL SEQUENCE
  • (unless you restoring 100% or
  • doing libraries one at a time where you specify which one each time)
• which means it will try to restore GETGOODIES before GOODSTUFF
• but if the physical file that a logical accesses is not on disk at time you try to restore the logical, you will not recover that from the backup
