To get a list of the dump class information for a specific type of volume managed by DFSMShsm, specify the LIST command with the DUMPCLASS(class) parameter. Table 1 explains the output labels when requesting dump class information.
| Printer Output Label (OUTDATASET or SYSOUT) | Terminal Label | Description |
|---|---|---|
| DUMP CLASS | CLASS | This field indicates the type of dump class for the unit type. |
| UNIT TYPE | UNIT | This field indicates the type of unit. |
| AUTO REUSE | REUSE | This field indicates (YES or Y, NO or N) whether the volume for this dump class is automatically available for reuse. |
| DATASET RESTORE | RESTORE | This field indicates (YES or Y, NO or N) whether to allow a physical data set restore from a full-volume dump copy for this dump class. |
| RESET CHANGE | RESET | This field indicates (YES or Y, NO or N) whether the change bit for each data set is to be reset by DFSMSdss following a successful full-volume dump. |
| CLASS DISABLE | DISABLE | This field indicates (YES or Y, NO or N) whether the dump class is disabled. |
| CP REQ | REQD | For a copy pool related dump, this field indicates whether the dump class is required or optional. A value of "**" (or "*" in terminal output) indicates that a value was not specified. This field has no significance for a non-copy pool dump. |
| FRR AVA | AVAILABLE | For a copy pool recovery, this field indicates (YES or Y, NO or N) whether the tapes related to this dump class are available to be mounted. This field has no significance for non-copy pool recoveries. |
| DAY | DAY | This field indicates the day in the dump cycle. This can be "**". |
| FREQ | FREQ | This field indicates the minimum number of days that must elapse between the last volume dump to this class and the next automatic dump. |
| RETPD | RETPD | This field indicates the number of days dump copies for this dump class must be retained. This can be *NOLIM. |
| TAPE EXPDT | TAPEEXPDT | This field indicates the expiration date for the dump copies created in this dump class. This can be "*******". |
| VTOC COPIES | VTOCCOPIES | This field indicates the number of VTOC copies. |
| STACK | STACK | This field indicates the maximum number of dump copies to be written to a dump volume in this dump class. This can be "**", which is treated the same as a value of one. |
| DISPOSITION | DISP | This field indicates the disposition of the dump volume of this unit type. This can be "********************". |
| HWCOMP | HWCOMP | This field indicates (YES or NO) whether the data will be compressed before it is encrypted. |
| ENCRYPT | ENCRYPT | This field indicates the type of encryption to be performed (NONE, RSA, KEYPASSWORD, or ICOUNT). |
| ENCTYPE | ENCTYPE | This field indicates the type of encryption to be performed (CLRAES128, CLRTDES, or ENCTDES). |
| ICOUNT | ICOUNT | This field indicates the number of hash iterations to perform on the password to generate the key. |
| RSAKEY/KPWD | ENC_KEY | This field indicates either the RSA key label, or the password used to encrypt the dump. |
| RECOVER |
RECRST | This field indicates whether or not DFSMSdss
resets (sets to OFF) the data-set-changed indicator (DS1DSCHA) in
the VTOC entry for all data sets that are restored during full volume
recover processing.

Figure 1 is a sample printer list of the dump classes when you specify the DUMPCLASS parameter. If you specify the parameter DUMPCLASS(class), only dump volumes of class are listed.
