The HF prevents future corruption should a new index block be needed for a multi-level index and the dbkey crosses the 32/64-bit boundary If there is existing index corruption, it needs to be fixed idxfix will not be able to find this corruption as it it does not traverse blocks like idxcheck does (even when the HF is applied). idxcheck only with validation Option 3 (Validate record for each key) will find 32-bit 64-bit corruption within a block split, but: - it can take a long time (even when the HF is applied). - it can cause a dbdown (before the HF is applied). Hence, if you have 'vulnerable' areas, it's a pretty good idea to rebuild those indexes after applying the HF. Alternatives may take longer to verify and not doing so will lead to having to get your DR notes out to recover, bearing in mind that this corruption will be propagated through AI notes ..
