Total Volume, Ixfp DDSR,PATEV3 | IBM SG24-5360-00 instruction

Notes:

When you do DDSR for expired files, VSE performs checking on the online (up) units.

DDSR checks only those RVA devices managed by the VSE system.

DDSR considers only the files created by VSE.

4.2.2 A Total Volume

It is possible to delete and release space for an entire volume when you include the device address or VOLID label with no other operands.

To illustrate, we use volume PATEV3 with device address 80F. To delete all data including the VTOC and VOLID label of PATEV3, issue the following command:

IXFP DDSR,PATEV3

The NOPROMPT parameter is included to prevent decision-type messages from being issued. Otherwise, decision-type messages are issued for the operator to verify and confirm (see Figure 16).


		AR	0015	1I40I	READY


		IXFP DDSR,PATEV3
		AR+0015 IXFP29D DDSR FOR				CUU=80F (WHOLE VOLUME) - REPLY ′ YES′ FOR DELETION
	15		YES
		AR	0015	1I40I	READY

Figure 16. Decision-Type Message Issued to Confirm DDSR Volume

Notes:

The device should belong to the RVA subsystem managed by the VSE system.

The device should be in the offline (DVCDN) condition.

The device should be reinitialized before you use it as a regular volume again. However, if you are going to use it as a target for a volume snap, you can leave it as is.

4.2.3 A Range of Cylinders

This command is similar to the DDSR volume command, except that additional specifications are added to signify the decimal start cylinder and end cylinder (dcyl-dcyl) or the decimal start cylinder and the number of cylinders (dcyl,ncyl) to delete.

To illustrate, we use volume PATEV3 with device address 80F. To delete all data from cylinders 0 through cylinder 999, issue the following command:

IXFP DDSR,PATEV3(0000-0999),NOPROMPT
