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.
When to run Run this test to verify the integrity of a particular piece of media, as
written and read by a particular drive, and to verify the ability of the
drive to read and write data independent of the storage application.
Average duration < 10 minutes, using default test options
Other notes Test will overwrite all data on the media.
This test can be stopped before it completes. To abort the test, click
Abort Test.

Performance tests
•
The Drive Performance Test writes data to a tape drive and calculates the performance of that
drive independently from the disk file system. Use this test in conjunction with the System
44 Tests and utilities
