Check Optical Volume (CHKOPTVOL)

The Check Optical Volume (CHKOPTVOL) command will validate that all directories and files on the volume can be read. If all directories and file data can be read successfully, the command will complete with no errors and the OUTPUT parameter specified determines whether or not to print a list of files and the number of bytes used. If any directory cannot be successfully read the command will complete in error with no output. If the directories can be read but all file data cannot be read, the command will complete in error and the OUTPUT parameter specified determines whether or not to print a list of damaged files, the number of files that are not damaged, and the number of bytes occupied for each.

Restrictions:

To use this command you must have *USE authority to the authorization list securing the volume.
If this command is being used to check a volume with the Universal Disk Format (UDF), the user must have *RWX authority to the volume root directory.

Keyword	Description	Choices	Notes
VOL	Volume identifier	Character value, ALL, MOUNTED	Required, Positional 1
OUTPUT	Output	ERROR, NONE, *PRINT	Optional, Positional 2
DEV	Optical device	Name, *ALL	Optional, Positional 3

Volume identifier (VOL)

*ALL: All optical volumes in the specified optical device (DEV parameter) are checked.
*MOUNTED: The volume mounted on the specified device (DEV parameter) is checked.
Note: This value is valid only for stand-alone optical devices, not for library devices.
volume-identifier: Specifies the volume identifier of the optical volume to be checked.
generic*-volume-identifier: Specify the generic name of the volume identifier. A generic name is a character string of one or more characters followed by an asterisk (*); for example, ABC*. The asterisk substitutes for any valid characters. A generic name will result in the check of all volumes which begin with the generic prefix and for which the user has authority. If an asterisk is not included with the generic (prefix) name, the system assumes it to be the complete object name.

Output (OUTPUT)

Specifies whether or not the output from the command is printed with the job's spooled output.

*ERROR: Print the list of damaged files to the job's spooled output only if there are any damaged files.
*NONE: The number of damaged files and the number of not damaged files will be in the completion message, but no spooled output file is generated.
*PRINT: Print to the job's spooled output even if there are not any damaged files.

Optical device (DEV)

Specifies the name of the optical device to use for the operation.

*ALL: When the VOL parameter is a specific name or a generic name the names of all of the optical volumes in all of the devices will be compared for a match.
name: When VOL(*MOUNTED) this is the name of the specified optical device. When the VOL(*ALL) all of the volumes in this device will be checked.

Note: This value is valid only when VOL(*ALL) or VOL(*MOUNTED) is specified. Otherwise this parameter is ignored.

Examples

Example 1: Check an Optical Volume

CHKOPTVOL   VOL(VOL01) OUTPUT(*ERROR)

This command checks the directories and files on VOL01. If any damaged files are found the file names are printed to the job's spooled output.

Example 2: Check an Optical Volume and Print the Results to the Job's Spooled Output

CHKOPTVOL   VOL(VOL01) OUTPUT(*PRINT)

This command checks the directories and files on VOL01 and prints a list of damaged files, the number of files that are not damaged, and the number of bytes occupied for each.

Example 3: Check Optical Volumes Using a Generic Volume Identifier

CHKOPTVOL   VOL(PAY*) OUTPUT(*ERROR) DEV(*ALL)

This command checks the directories and files on all volumes in all optical devices that start with PAY. Spooled output created only if error occurs.

Example 4: Check all Optical Volumes in an Optical Media Library

CHKOPTVOL   VOL(*ALL) OUTPUT(*ERROR) DEV(OPTMLB01)

This command checks the directories and files on all volumes in optical media library OPTMLB01.
