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 read in each phase:

Time

—Limits the amount of data read based on the time

specified in Data Time Limit.

Size

—Limits the amount of data read based on the size

specified in Data Size Limit.

Whole tape

—Limits the amount of data read based on the

size of the tape.

Amount of data read in each phase

—Specify the size

limit in megabytes of data to be read in each phase.

Time allowed for each data test phase

—Specify the

time limit, in minutes, for each phase of the test.

Transfer Size Limit

—Specify the maximum data transfer

limit, in kilobytes, per command.

When to run

Run this test when you want to verify the integrity of the data on a
particular piece of media, as read by a particular drive.

Average duration

< 5 minutes, using default test options

Other notes

The Media Analysis test reads data from the media and calculates the
error rate. If the error rate exceeds the maximum allowable threshold,
the test will require a cleaning cartridge and a second tape to determine
if the problem is with the drive or the tape.

Test is non-destructive and will not overwrite any data on the media.

Available for

This test is available for all tape drives except for LTO. For LTO tape
drives, use the

LTO Media Assessment test (page 123)

.

Media Validation test

Description

This test reads data on the tape cartridge, magneto-optical (MO), or
ultra-density optical (UDO) media in your storage device. No writes are
performed, so data contents of the media are not changed in any way.
Supports several test options for MO and UDO media (data limit options,
starting block, block size, failure threshold, and so on), but none for
tape. The test also runs a self test and cleaning check, and prompts for
cleaning cartridge if it deems necessary (tape only).

NOTE:

For some devices, the Media Validation test has been

superseded with the Media Analysis test.

NOTE:

For instructions on how to perform this test, see

Running the

tests (GUI) (page 40)

or

Running the tests (CSI) (page 73)

.

When to run

Run this test when you suspect a problem with your media.

Average duration

< 5 minutes using default test options, but dependent on the amount of
data on the media. Can take longer if media is full.

Other notes

Test requires that a minimum amount of data is already written on the
media, otherwise the test will fail. The amount of data varies depending
on drive technologies and options (in the case of MO media).
