SAVCFG (Save Configuration)

SAVCFG Command syntax diagram

 

Purpose

The Save Configuration (SAVCFG) command saves all configuration and system resource management (SRM) objects without requiring a system in a restricted state. The information saved includes the following:

Information saved can be restored with the RSTCFG command.

 

Restrictions

  1. You must have *SAVSYS special authority to use this command.

  2. SAVCFG data cannot be saved to a diskette device.

  3. System resource management (SRM) objects are not saved if a Work with Hardware Products (WRKHDWPRD) job is running at the same time.

  4. Specifying USEOPTBLK(*YES) may result in a tape that can be duplicated only to a device that supports the same block size.

 

Required Parameters

DEV
Specifies the name of the device on which the configuration information is to be saved. The device name must be known on the system by a device description.

*SAVF: The save operation uses the save file specified on the SAVF parameter.

optical-device-name: Specify the name of the optical device used for the save operation.

tape-media-library-device-name: Specify the name of the tape media library device used for the save operation.

tape-device-name: Specify the name of one or more tape devices used for the save operation. If more than one tape device (up to four) is being used, specify the names of the devices in the order they are used. If more than one tape volume is required, the use of more than one tape device allows one tape volume to be rewound and unloaded while the tape on another device is being processed.

 

Optional Parameters

VOL
Specifies the volume identifiers of the volumes, or the cartridge identifier of a tape in a tape media library device, on which the data is saved. The volumes must be placed in the device in the order specified on this parameter. More information on this parameter is in Commonly used parameters.

*MOUNTED: The data is saved on the volumes placed in the device. For a media library device, the volume to be used is the next cartridge in the category mounted by the Set Tape Category (SETTAPCGY) command.

volume-identifier: Specify the identifiers of one or more volumes in the order in which they are put on the device and used. Each volume identifier contains a maximum of 6 alphanumeric characters. A blank is used as a separator character when listing multiple identifiers.

SEQNBR
Specifies the sequence number used as the starting point for the save operation when a tape is used.

*END: The system saves the file starting after the last sequence number on the first tape. If the first tape is full, an error message is issued and the operation ends.

sequence-number: Specify the sequence number of the file. Valid values range from 1 through 16777215.

EXPDATE
The file is permanently protected.

*PERM: The save and restore files are permanently protected.

expiration-date: Specify the date when the file protection ends.

ENDOPT
Specifies the operation that is automatically performed on the tape or optical volume after the save operation ends. If more than one volume is used, this parameter applies only to the last volume used; all other volumes are unloaded when the end of the volume is reached.

Note: This parameter is valid only if a tape or optical device name is specified on the DEV parameter. For optical devices, *UNLOAD is the only special value supported, *REWIND and *LEAVE will be ignored.

*REWIND: The tape is automatically rewound, but not unloaded, after the operation has ended.

*LEAVE: The tape does not rewind or unload after the operation ends. It remains at the current position on the tape drive.

*UNLOAD: The tape is automatically rewound and unloaded after the operation ends. Some optical devices will eject the volume after the operation ends.

SAVF
Specifies the qualified name of the save file used to contain the save data. The save file must be empty or CLEAR(*ALL) must be specified.

The name of the save file can be qualified by one of the following library values:

*LIBL: All libraries in the job's library list are searched until the first match is found.

*CURLIB: The current library for the job is searched. If no library is specified as the current library for the job, the QGPL library is used.

library-name: Specify the name of the library to be searched.

save-file-name: Specify the name of the save file.

CLEAR
Specifies whether active data on the media is automatically cleared or replaced. Active data is any file on the media that has not expired. Clearing active data removes all files from the volume, starting at the specified sequence number for tape. Replacing active data on optical media replaces only the optical files created by this operation.

 

Notes

  1. Clearing a tape does not initialize it. You should initialize tapes to a standard label format before the save command is issued by using the Initialize Tape (INZTAP) command and specifying a value on the NEWVOL parameter.

  2. Clearing an optical volume does initialize it.

  3. Clearing a diskette does not initialize it. You should initialize diskettes to a save and restore format before the save command is issued by using the Initialize Diskette (INZDKT) command and specifying FMT(*SAVRST).

  4. If a volume that is not initialized is encountered during the save operation, an inquiry message is sent and an operator can initialize the volume.

*NONE: None of the media is automatically cleared. If the save operation encounters active data on a tape, diskette, or save file, an inquiry message is sent, allowing the operator to either end the save operation or clear the media. If the save operation encounters the specified optical file, an inquiry message is sent, allowing the operator to either end the save operation or replace the file.

*ALL: All of the media is automatically cleared.

If tapes are used and a sequence number is specified on the SEQNBR parameter, the first tape is cleared beginning at that sequence number. All tapes following that first tape are completely cleared. To clear the entire first tape, SEQNBR(1) must be specified.

*AFTER: All media after the first volume is automatically cleared. If the save operation encounters active data on the first tape or diskette, an inquiry message is sent, allowing the operator to either end the save operation or clear the media. If the save operation encounters the specified optical file on the first volume, an inquiry message is sent, allowing the operator to either end the save operation or replace the file.

Note: The *AFTER value is not valid for save files.

*REPLACE: Active data on the media is automatically replaced. Optical volumes are not initialized. Tapes, diskettes, and save files are automatically cleared in the same way as the *ALL value.

PRECHK
Specifies whether the save configuration operation ends if any of the objects satisfy the following conditions:

  • The objects were previously found to be damaged.

  • The objects are locked by another job.

  • The user does not have authority to save the objects.

*NO: The save operation continues, saving only configuration and system resource management (SRM) objects that can be saved.

*YES: The save operation ends before any data is written if any configuration objects or system resource manager objects cannot be saved.

DTACPR
Specifies whether data compression is performed.

*DEV: If the tape device has the hardware compression feature installed, processing proceeds as if DTACPR(*YES) is specified. If the compression feature is not specified or if save data is written to optical or a save file, processing proceeds as if DTACPR(*NO) is specified.

Note: If *DEV is specified on both the DTACPR parameter and the COMPACT parameter, only device data compaction is performed if compaction is supported on the device. Otherwise, data compression is performed if supported on the device.

If *YES is specified on the DTACPR parameter and *DEV is specified on the COMPACT parameter, both device data compaction and device data compression are performed if supported on the device.

*NO: No data compression occurs.

*YES: If the save is to tape and the target device supports compression, hardware compression is performed. If compression is not supported, or the save data is written to optical or a save file, software compression is performed. If the save is running while other jobs on the system are active and software compression is used, overall system performance may be affected.

COMPACT
Specifies whether data compaction is performed.

*DEV: Device data compaction is performed if the data is saved to tape and all tape devices specified on the DEV parameter support the compaction feature.

Note: If *DEV is specified on both the DTACPR parameter and the COMPACT parameter, only device data compaction is performed if compaction is supported on the device. Otherwise, data compression is performed if supported on the device.

If *YES is specified on the DTACPR parameter and *DEV is specified on the COMPACT parameter, both device data compaction and device data compression are performed if supported on the device.

*NO: Device data compaction is not performed.

OUTPUT
Specifies whether a list with information about the saved objects is created. The information can be printed with the job's spooled output or directed to a database file.

*NONE: No output listing is created.

*PRINT: The output is printed with the job's spooled output.

*OUTFILE: The output is directed to the database file specified on the OUTFILE parameter.

Note: If OUTPUT(*OUTFILE) is specified, specify the database file name on the OUTFILE parameter.

OUTFILE
Specifies the qualified name of the database file to which the information about the object is directed when *OUTFILE is specified on the OUTPUT parameter. If the file does not exist, this command creates a database file in the specified library. If a new file is created, the system uses QASAVOBJ in QSYS with the format name QSRSAV as a model.

The name of the database file can be qualified by one of the following library values:

*LIBL: All libraries in the job's library list are searched until the first match is found.

*CURLIB: The current library for the job is searched. If no library is specified as the current library for the job, the QGPL library is used.

library-name: Specify the name of the library to be searched.

database-file-name: Specify the name of the database file to which the output of the command is directed.

OUTMBR
Specifies the name of the database file member to which the output of the command is directed when *OUTFILE is specified on the OUTPUT parameter.

Element 1: Member to Receive Output

*FIRST: The first member in the file receives the output. If OUTMBR(*FIRST) is specified and the member does not exist, the system creates a member with the name of the file specified on the OUTFILE parameter.

member-name: Specify the name of the file member that receives the output. If OUTMBR(member-name) is specified and the member does not exist, the system creates it. If the member exists, the user can add records to the end of the existing member or clear the existing member and add the records.

Element 2: Operation to Perform on Member

*REPLACE: The existing records in the specified database file member are replaced by the new records.

*ADD: The new records are added to the existing information in the specified database file member.

OPTFILE
Specifies the path name of the optical file that is used for the save operation, beginning with the root directory of the volume. For more information on specifying path names, refer to path names.

'*': The system generates an optical file name in the root directory of the optical volume.

'optical-directory-path-name/*': The system generates an optical file name in the specified directory of the optical volume.

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

*YES: The optimum block size supported by the device is used for Save commands. If the block size that is 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) 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 DTACPR parameter is ignored.

If the target release value that is specified is earlier than V3R7M0 then the block size supported by all device types is used.

*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.

Examples for SAVCFG

Example 1: Saving Objects 

SAVCFG  DEV(TAP01)  CLEAR(*ALL)

This command saves system resource management objects (hardware resource data and token-ring adaptor data) and all configuration objects (including all line, controller, device, mode, class-of-service, and network descriptions, configuration lists, and connection lists). They are saved on the TAP01 tape drive. CLEAR(*ALL) automatically clears all uncleared tapes when they are encountered.

Example 2: Saving Objects to a Specific Tape 

SAVCFG  DEV(TAP01)  VOL(ABC)

This command saves the SRM and configuration objects on the TAP01 tape drive, starting on the tape volume labeled ABC. If the save operation exceeds the storage capacity of one tape, a message requesting that another volume be put on the TAP01 tape drive is issued.
