This command specifies a reservepagegap of 10 for nonclustered index pages:
create index type_price_ix on more_titles(type, price) with reservepagegap = 10
You can specify a reservepagegap value with the alter table...constraint options, primary key and unique, that create indexes. The value of reservepagegap for local index on partitioned tables applies to all local index partitions.
This example creates a unique constraint:
alter table more_titles add constraint uniq_id unique (title_id) with reservepagegap = 20
