DFS3126W RDS DATA SET REFORMAT REQUIRED DURING NEXT RESTART

Explanation
 A write error occurred on the restart data set
(RDS) during a checkpoint. The operation continues because the RDS
data set is not required during online execution except to save information
needed for the next restart. However, the next restart will access
the disk log to obtain information to restart the system. At this
time a reformat of the RDS data set must be done.

System action
 The operation continues, but the system will
stop logging data to the RDS data set. The system will shut down normally
when instructed to do so.

Programmer response
 Check the allocation
of the restart data set.  The RDS allocation needs to be large enough
to contain at least 90 blocks reserved for RDS1 components BCPT, RRE,
SIDX, and LCRE.
During the next restart of the system, reformat
the RDS data set by specifying FORMAT RS in the restart
command. If this problem persists, you must perform a scratch, reallocation,
and reformat of the RDS.
