It is a state of the table being locked due to constraint
violation.
For eamaple if you try to nullify the master table alone
and reloading it with some additional records without
deleting detail table records or vise versa, the master and
the child tables whill go to the check pending state.
You can check the same with the help of the below query.
select tabname from syscat.tables where status='C';
To clear the same we can use the following statements.
set integrity for master immediate checked for exception in
master use exception_table;
the violated records will be moved to exception table and
the check pending will be cleared.

1. When you use ALTER TABLE to add a check constraint to already populated tables, and CURRENT RULES special register is DB2®, the check constraint is added to the table description but its enforcement is deferred. Because there might be rows in the table that violate the check constraint, the table is placed in CHECK-pending status.
2. When a table is LOADed with ENFORCE NO option, then the table is left in CHECK PENDING status as DB2 bypasses referential integrity and check constraints
3. An index might be placed in CHECK-pending status if you recovered an index to a specific RBA or LRSN from a copy and applied the log records, but you did not recover the table space in the same list. The CHECK-pending status can also be set on an index if you specified the table space and the index, but the recovery point in time was not a point of consistency (QUIESCE or COPY SHRLEVEL REFERENCE).
To reset this status, run the CHECK DATA utility, which locates invalid data and, optionally, removes it. If CHECK DATA removes the invalid data, the remaining data satisfies all check and referential constraints and therefore, the CHECK-pending restriction is removed.
1. If a table space is in both REORG-pending and CHECK-pending status (or auxiliary CHECK-pending status), run the REORG TABLESPACE utility first and then run CHECK DATA to reset the respective states.
2.Run the CHECK INDEX utility on the index. If any errors are found, use the REBUILD INDEX utility to rebuild the index from existing data.
3.Use the REPAIR utility with the SET STATEMENT and NOCHECKPEND option.
Following jobs remove copy pending and recovery pending status from a table space and removes copy pending, recovery pending status and rebuild pending status from an index space

Answer / kamal singh
It comes into existencw when constraint checking is
suspended for a particular table. Let me explain with the
help of an example:
If we want to temporarily suspend constraint checking for a
table named EMPLOYEES and deny read-only access to that
table while constraint checking is turned off, we could do
so by executing a SET INTEGRITY statement that looks
something like this:
SET INTEGRITY FOR EMPLOYEES OFF
When constraint checking is suspended for a particular
table, that table is placed in "Check Pending" state to
indicate that it contains data that has not been checked
(and that may not be free of constraint violations). While
a table is in "Check Pending" state, it cannot be used in
insert, update, or delete operations, nor can it be used by
any DB2 UDB utility that needs to perform these types of
operations. In addition, indexes cannot be created for a
table while it is in "Check Pending" state, and data stored
in the table can be retrieved only if the access mode
specified when the SET INTEGRITY statement was used to
place the table in "Check Pending" state allows read-only
access.
