Options •
Looping options
Specify Count based loop or Time based loop(min). In either case, the actual value
is entered separately using the Looping value parameter.
Example 1 To set a time-based loop of 10 minutes:
testopt=”Looping Options:Time based loop(min)”
testopt=”Looping value:10”
•
Looping value
Specify an integer greater than zero.
Example 2 To set a count-based loop to iterate five times:
testopt=”Looping Options:Count based loop”
testopt=”Looping value:5”

LTO Cooling Check test
Table 15 Cooling Check test details
Cooling Check test Details/Other test
This test monitors the temperature sensors of an LTO drive while writing data to ensure
that the drive is cooling properly when installed in a server. Description
NOTE: For instructions on how to perform this test, see “Running tests and
device-specific utilities” (page 29) or “Running the tests (CSI)” (page 50) .
Run this test if you suspect thermal problems with your LTO drive. When to run
None Duration
This test can be stopped before it completes. To abort the test from the GUI, click Abort
Test. To abort the test from the CSI, use the Ctrl-A key combination. Other notes
LTO drives Available for
Data Compression test
CAUTION: This test is destructive and will overwrite data on the media that is present in your
product.
Table 16 Data Compression test details
Data Compression test Details/Other test
Tests the hardware compression capability of your tape drive. The test writes a data
pattern of known compressibility to tape. The test then rewinds the tape and reads the Description
file just written. The read and write hardware compression ratios are calculated to
ascertain that the hardware compression is working. The compression ratios are
displayed and should be approximately 2:1. Anything less than 2:1 means that
hardware compression is not working. This test is useful if tape capacity or hardware
compression is in doubt.
