Options

• Test Time Limit—Specify the time limit in minutes. Enter 0 for no time limit.

• Data Limit Type—Specify one of the following options to limit the amount of data

written/read in each phase:

◦ Time—Limits the amount of data tested based on the time specified in Data Time

Limit.

◦ Size—Limits the amount of data tested based on the size specified in Data Size

Limit.

◦ Whole tape—Limits the amount of data tested based on the size of the tape.

• Data Size Limit—Specify the size limit in megabytes of data to be written/read in

each phase.

• Data Time Limit—Specify the time limit, in minutes, for each phase of the test.

• Block Size—Specify the block size, in kilobytes, to be used in the test. The default

is 64 KB.

• Transfer Size Limit—Specify the maximum data transfer limit, in kilobytes, per

command. The default is 64 KB.

• Block Transfer Type—Specify whether to use a fixed or variable block length.

• Read and compare after the write operation—Set this option to true to enable the

read phase after the write phase completes. This option is optional and is set to

false by default. The read phase also compares the buffers written during the write

operation to ensure data integrity on the tape.

• Retry on read failure—When on, the test will prompt the user for a cleaning cartridge

and a new test cartridge in the case of repeated read failures.

• Compression Ratio—Specify the compression ratio for the test. The test will use a

buffer pattern in a pre-specified format to achieve the specified compression ratio.

• Write filemarks after every—Specify whether the test should write a filemark on the

tape after every specified amount of data.

The test will overwrite all data on the media. This test can be stopped before it

completes. To abort the test from the GUI, click Abort Test. To abort the test from the
