NAME

generate_test_tape - perform generates a test tape for diagnostic purposes.

SYNOPSIS

generate_test_tape: -f device [ -z blocksize ] [ -s filesize ] [ -b maxblocks ] [ -m maxfiles ] [ -v ]

DESCRIPTION

The generate_test_tape program generates a test tape mounted on a device for diagnostic purposes. 32 KB blocks are first written to the tape mounted on the device, with a filemark at every N number of blocks it has completed writing the total number of blocks specified by the user, or till it reaches end of tape.

OPERANDS

-f

device

: Specifies the device to generate the test tape on.

OPTIONS

-b

maxblocks

: Use the -b option to specify the maximum number of blocks to write to tape. The value of maxblocks must be greater than 0. If the -b and the -m options are not specified, the program will write to the end of tape or till a write error is encountered.

-m

maxfiles

: Use the -m option to specify the maximum number of files to write to tape. The value of maxfiles must be greater than 0. If the -b and the -m options are not specified, the program will write to the end of tape or till a write error is encountered.

-s

filesize

: Use the -s option to specify the file size (in number of blocks) to write to tape. The value of filesize must be greater than 0. The default file size is 1000 32KB blocks.

-sz

blocksize

: Use the -s option to specify the block size (in number of 1KB) to write to tape. The value of blocksize must be greater than 0. The default block size is 1000 32KB.

-v

Run the program in verbose mode. This option will print out the version number of the CDI library used by the program.

EXAMPLES

Sample output including drive status information:



% generate_test_tape -f /dev/rmt/3cbn -b 20 -s 2 -v


ready to fill tape on QUANTUM


DLT7000          using device file /dev/rmt/2cbn


each tape record will be 32768 bytes


a filemark will be written every 2 records


the process will end when 20 total records have been written to the tape
