Device (DEV)

Specifies the names of the devices used for save media information operation. Each device name must already be known on the system in the BRMS device table. If multiple devices are specified, they must use the same media classes. If more than one device is used, specify the names of the devices in the order in which they are used.

This is a required parameter.

You can enter multiple values for this parameter.

Single values

*MEDCLS: Any device that supports the media class specified in the media policy can be used for this save operation.

Other values (up to 4 repetitions)

*NONE: The save operation is to a save file.
device-name: Specify the name of the device or devices that you want to use for this save operation.

Media policy (MEDPCY)

Specifies the media policy for the volumes you are creating as a result of saving media information.

Media policies are used to determine:

The type of retention to use, such as days, date or version, for media used in control group processing.
The move policy to use with this media policy.
The media class to use.
Whether or not to use save files.
The type of retention to use, such as days or date for save files created in control group processing.

The media policy you specify must be a media policy that is in the BRMS media policy table.

This a required parameter.

*NONE: No media policy is specified for this save operation. Media policy values must be supplied with the save command for each parameter that has a default of *MEDPCY.
*SYSPCY: The media policy specified in the system policy is assigned to output volumes from this save operation.
media-policy: Specify the name of the media policy that you want to use with this save operation.

Option (OPTION)

Specifies whether you want to save media information at the object or library level.

*LIB: You save media information at the library level. Recovery can only be done for libraries, not individual objects in libraries.
*OBJ: You save media information at the object level. Recovery can be done for libraries, individual objects in libraries or members in physical files.

Control group (CTLGRP)

Specifies the name of the control group that you want to associate with the objects saved by this command. The control group name is stored with the media information and can be used with the Control group (CTLGRP) parameter on other BRMS commands to filter the media information or recover saved objects by control group.

Note: None of the attributes of the control group are used for the save.

If you are using version control for the items you are saving, this save operation will be recorded as part of the specified version control. Version control is specified in the media policy associated with this control group and can be reviewed by using the Work with Media Policies display.

*NONE: Do not specify a control group name for this command.
*ARCGRP: The name of the default archive control group.
Note: The BRMS Advanced feature (Option 2) is required to use this value.
*BKUGRP: The name of the default backup control group used to save all user data.
*SYSGRP: The name of the default system control group used to save all system data.
*SYSTEM: The name of the default system control group used to save the entire system.
control-group-name: Specify the name of the control group to be assigned to the items you are saving.

End of tape option (ENDOPT)

Specifies, when tape is used, what positioning operation is automatically done on the volume after the save operation ends. If more than one volume is included, this parameter applies only to the last volume used; all other volumes are rewound and unloaded when the end of the volume is reached.

If you specify *LEAVE and the device is a shared device, the device will not be varied off after the save operation. If you specify *LEAVE and the device is not a shared device, the device will be varied off after the save operation.

*REWIND: The volume is automatically rewound, but not unloaded, after the operation has ended.
*LEAVE: The volume does not rewind or unload after the operation ends. It remains at the current position on the device.
*UNLOAD: The volume is automatically rewound and unloaded after the operation ends.

Use optimum block size (USEOPTBLK)

Specifies whether or not the optimum block size is used for the save operation.

*BKUPCY: Use the value from the backup policy for the Use optimum block size parameter.

*DEV: Use the value specified on the Work with Devices display for the Use optimum block size parameter.

*NO: The optimum block size supported by the device is not used. Save commands use the default block size supported by all device types. The tape volume can be duplicated to any media format using the Duplicate Tape (DUPTAP) command or the Duplicate Media using BRM (DUPMEDBRM) command.

*YES

The optimum block size supported by the device is used for Save commands. If the block size used is larger than a block size that is supported by all device types then:

Performance may improve.
The tape file that is created is only compatible with a device that supports the block size used. Commands such as Duplicate Tape (DUPTAP) and Duplicate Media using BRM (DUPMEDBRM) do not duplicate files unless the files are being duplicated to a device which supports the same block size that was used.
The value for the Data Compression (DTACPR) parameter is ignored.

Sequence number (SEQNBR)

Specifies, when tape is used, the sequence to use for the save operation. If you are saving to a BRMS volume that is expired, BRMS will begin writing information at the beginning of the volume, even though you have specified *END. If you are saving to a BRMS volume, BRMS will redirect the output to begin at the logical end of the output volume (after the end of the last active file), depending on the output device that you are using. For example, a 3490 device can write to any sequence number whereas a 6525 device can only write to sequence number 1 or *END.

*END: The save operation begins after the sequence number of the last active file on the volume.
file-sequence-number (1-16,777,215): Specify the sequence number of the file to be used for the save operation.

Target release (TGTRLS)

Specifies the release of the operating system on which you intend to restore the objects being saved.

*CURRENT: The objects are to be restored on a system that is running the same release of the operating system currently running on your system. For example, if V5R2M0 is running on the system, *CURRENT means that you intend to restore the objects on a system with V5R2M0 installed. The objects can also be restored on a system with any subsequent release of the operating system installed.

*PRV: The objects are to be restored on a system that is running on the previous release with modification level 0 of the operating system. For example if V5R2M0 is running on your system, *PRV means you intend to restore the objects on a system with V5R1M0 installed. The object can also be restored on a system with any subsequent release of the operating system installed.
Note: Not all objects can be targeted to another release. Objects that are new to a release typically cannot be saved to a previous release.

target-release

Specify the release in the format VxRxMx, where Vx is the version, Rx is the release, and Mx is the modification level. For example, V5R2M0 is version 5, release 2, modification level 0.

The objects can be restored on a system with the specified release or with any subsequent release of the operating system installed.

Note: Not all objects can be targeted to another release. Objects that are new to a release typically cannot be saved to a previous release.

Valid values depend on the current version, release, and modification level, and they change with each new release. If you specify a release-level that is earlier than the earliest release level supported by this command, an error message is sent indicating the earliest supported release.

Clear (CLEAR)

Specifies whether uncleared volumes or save files encountered during the save operation are automatically cleared.

*NONE: None of the uncleared volumes or save files encountered during the save operation are automatically cleared. If the save operation cannot proceed because an uncleared volume is encountered, an inquiry message is sent to the operator, allowing the ending of the save operation, or specifying that the currently selected volume be cleared so the operation can continue.
If a save file is not cleared, the inquiry message is sent to the work station message queue for an interactive job, or to the operator for a batch job. All volumes used to perform the save operation should be cleared, or the save file must be empty, before the save command is issued.
*AFTER: All the uncleared volumes after the initial volume are automatically cleared. This option is not valid for save or restore operations to a save file. If the operation cannot proceed because the first volume is uncleared, an inquiry message is sent to the system operator, allowing him to end the operation or to specify that the currently selected volume be cleared so the operation can continue.
*ALL: All the uncleared volumes or save files encountered during the save operation are automatically cleared. If tapes are used and a sequence number is specified, the volume is cleared and, starting with that sequence number, all volumes following the first volume are cleared.

Save access paths (ACCPTH)

Specifies whether the logical file access paths that are dependent on the physical files being saved are also saved. The access paths are saved only if all members on which the access paths are built are included in this save operation. Informational messages are sent indicating the number of logical file access paths saved with each physical file. This parameter does not save logical objects; it only controls the saving of the access paths. Information on the restoring of saved access paths is in the Backup and Recovery Book.

*SYSVAL: The system value QSAVACCPTH determines whether to save the logical file access paths that are dependent on the physical files that are being saved.
*NO: Only those objects specified on the command are saved. No logical file access paths are saved.
*YES: The specified physical files and all eligible logical files access paths over them are saved.
