Figure 4-9 illustrates STATUS command parameters. · · You can specify target data by DDNAME, (using volume, unit and disp number), VOLUME (volume serial number) or DEVICE (device number). You can specify a target data range as either DKU (a volume defined by DDNAME or volume) or DKC (all volumes in the same storage system ID). (DKU is the default value. ) EXTENT specifies that cache extent information will be printed. NOEXTENT specifies that cache extent information will not be printed. (NOEXTENT is default value. ) DSEXTENT specifies that extent information of dataset statistics will be printed. If this is combined with a DKC command, you must also define RAIDPARM.

Define a dataset to store the device number. Define a dataset to store the control statements. 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'. (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. EXTENT defines the cache extent as all volumes that belong to same storage system ID (SSID). (9) End of job. Figure 4-13 Volume STATUS Command Performing Cache Manager Operations Hitachi Cache Manager User's Guide 4-11 Figure 4-14 illustrates a sample JCL for a dataset STATUS command.
