Recoverability of a rebuilt index

When you successfully rebuild an index that was defined with COPY YES, utility processing inserts a SYSCOPY row with ICTYPE='B' for each rebuilt index. Rebuilt indexes are also placed in informational COPY-pending status, which indicates that you should make a copy of the index.

Recommendation: If you have FlashCopy® capability, create a FlashCopy image copy during the REBUILD INDEX. Alternatively, after the index is rebuilt, make a sequential full image copy of the index to create a recovery point. Both copy methods reset the ICOPY status of the rebuilt index.
