One problem with damaged anything is that the damage interferes with determining what needs to be fixed.

An index might include three columns and the damage makes one of the column identifiers unreadable. If the index object cannot describe itself properly, it can be impossible to "rebuild". It could only be "recreated".

In short, it's impossible to answer the question accurately without knowing what types of damage happened.

However, "damage" might refer to access paths that are marked as 'Invalid'. These access paths are marked this way when the system ends abnormally while the members are open. Control over rebuilding these access paths is through the EDTRBDAP (Edit Rebuild Access Paths) command.

The options should be fairly obvious once the command displays its list. Rebuilding can be done for any or all APs during IPL, after IPL or when a program opens the AP. You choose how each one should be handled.

Post back and ask for details on elements that you need more info about.
