Savvio 10K.2 SAS Product Manual, Rev. E

After a self-test is complete or has been aborted, the drive updates the Self-Test Results Value field in its Self-

Test Results Log page in non-volatile memory. The host may use Log Sense to read the results from up to the

last 20 self-tests performed by the drive. The self-test results value is a 4-bit field that reports the results of the

test. If the field is set to zero, the drive passed with no errors detected by the DST. If the field is not set to zero,

the test failed for the reason reported in the field.

The drive will report the failure condition and LBA (if applicable) in the Self-test Results Log parameter. The

Sense key, ASC, ASCQ, and FRU are used to report the failure condition.

6.2.6.2.5

Abort

There are several ways to abort a diagnostic. You can use a SCSI Bus Reset or a Bus Device Reset message

to abort the diagnostic.

You can abort a DST executing in background mode by using the abort code in the DST Function Code field.

This will cause a 01 (self-test aborted by the application client) code to appear in the self-test results values

log. All other abort mechanisms will be reported as a 02 (self-test routine was interrupted by a reset condition).

See Section 1.0 for warranty contact information.

Shipping

When transporting or shipping a drive, use only a Seagate-approved container. Keep your original box.

Seagate approved containers are easily identified by the Seagate Approved Package label. Shipping a drive in

a non-approved container voids the drive warranty.

Seagate repair centers may refuse receipt of components improperly packaged or obviously damaged in tran-

sit. Contact your authorized Seagate distributor to purchase additional boxes. Seagate recommends shipping

by an air-ride carrier experienced in handling computer equipment.

Storage

The maximum recommended storage period for the drive in a non-operational environment is 90 days. Drives

should be stored in the original unopened Seagate shipping packaging when ever possible. Once the drive is

removed from the Seagate original packaging the recommended maximum period between drive operation

cycles is 30 days. During any storage period the drive non-operational temperature, humidity, wet bulb, atmo-

spheric conditions, shock, vibration, magnetic and electrical field specifications should be followed.

Product repair and return information

Seagate customer service centers are the only facilities authorized to service Seagate drives. Seagate does

not sanction any third-party repair facilities. Any unauthorized repair or tampering with the factory seal voids

the warranty.
