Viewing drive utilization
To access utilization information for a specific drive:
1.
In the ALL LTT Service Hosts screen, select the service host associated with the tape drive.
2. In the left panel, click TapeAssure.
3. In the navigation panel under Drives, select Utilization. A list of the tape drives managed by
the selected service host appears.
The TapeAssure Utilization window lists:
•
Library SN (or Hostname)—Shows the hostname of the server to which the drive is attached.
Such hostname entries are highlighted with an asterisk (*).
•
Drive Type—The drive type including generation and interface type.
•
Library Serial Number—The HP serial number that uniquely identifies the library. Defined at
manufacture, this is the number to quote when contacting HP support.
•
Sample Size—The Interface Manager samples data from the drive by retrieving key statistics
from the drive. This occurs after a tape unload, or whenever a user generates a support ticket.
A sample refers to one instance of pulling the key statistics from the drive. The sample size is
the number of times the TapeAssure feature has retrieved these key statistics within the user
selected sample time.
•
Utilization (%)—Measure of the time that the tape drive has been pulling tape divided by the
amount of time that the tape drive has been powered on. Use this for measuring utilization
from the hardware standpoint.
•
Last Sample Time—The local time when the key data was written to the database.
When a management station is reconnected to the network after more than 24 hours offline, the
utilization panel display can be inaccurate. The TapeAssure data queued up on active drives and
libraries arrives in bulk. To display a more accurate utilization, select Actions
→Choose Sample
Time, and choose the next longest time frame (7 days or more).
To choose the time frame for the data samples:
1.
In the Utilization panel select Actions
→Choose Sample Time.
2. Select the sample time and click OK.
