Device analysis test – HP StoreEver TapeAssure Software User Manual
Page 32

Description
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 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.
When to run
Run this test when you want to verify that data compression is working
properly.
Average duration
< 10 minutes
Other notes
Test will overwrite all data on the media.
Available for
All tape products (drive and automation) supported by L&TT
Device Analysis test
Description
The Device Analysis test runs a device-specific script that carries
out a detailed examination of the device. The test examines all
available logs from the device to look for any known issues,
customer use issues, and common error patterns. The test also
provides summary information and presents suggestions as to the
cause of certain errors and any remedial actions the user should
take. This option is particularly useful if you suspect that there may
be a problem with the device.
The Device Analysis test can be executed manually through the Tests
screen or automatically whenever a support ticket is generated. The
Device Analysis test is unique among all the tests offered by L&TT.
In addition to performing SCSI operations directly on a device, the
Device Analysis test uses a set of predefined, device-specific rules
to analyze device logs and configurations. If any known issues are
discovered during the analysis, the user is notified of the problem
and the program suggests an appropriate course of action.
The Device Analysis test automates failure analysis of a device by
determining
•
whether a known or unknown problem with a device exists
•
if the problem can be resolved in the field through maintenance
or simple repair
•
whether a device needs to be returned or serviced
Command line syntax

When to run
Run this test when you want to verify that basic functions of the
device are operating properly and have not logged any critical
errors, and to verify that firmware is up to date.
Average duration
< 1 minute
Other notes
