(1) Start of job.
(2) Execute HRUDCRX.
(3) Spool the message dataset.
(4) Define a dataset to store the device number.
(5) Define a dataset to store the control statements.
(6) Edit the cache status, nonvolatile memory status and capacity information and store them in the dataset.
VOLUME defines a volume serial number in the cache storage system. DKU is a required parameter to specify
the entire volume of ‘CSVOL2’. DSEXTENT processes dataset statistics information of specified datasets.
(7) Edit the cache status and extent information and store them in the dataset. VOLUME defines a volume serial
number in the cache storage system. DKC specifies all volumes with the same storage system ID (SSID). This is
necessary to define the RAIDPARM DD statement. DSEXTENT processes specified dataset statistics information
for all volumes with the same storage system ID (SSID).
(8) End of command.
(9) End of job.
