Assume you alter the hash index to use a sparse map:
ALTER HASH INDEX ord_cust_hidx, MAP=SmallTableMap;
This example returns the create text for hash index ord_cust_hidx in XML format:
SHOW IN XML HASH INDEX ord_cust_hidx;
The XML document generated reports all of the information required to recreate the hash index:
