Drive Operation Test

For each drive on the storage device, this test reports the speed of the drive and the rate of tag creation on the dive.

Target of the test : A Hitachi AMS storage device

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each drive on the Hitachi AMS device being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.


The IP address of the storage device.


Specify the name of the storage unit to be monitored. To determine the unit name registered with the Storage Navigator Client for the AMS SAN device, run the following commands, one after another, from the C:\Program Files\Storage Navigator Modular CLI directory on the Storage Navigator Client:



The output of the command includes the Name of the storage unit. DF700M_75011118 is a sample unit name.


Indicate the machine type. The value can be AMS or WMS. By default, this parameter is set to AMS.


Specify the full path to the install directory of the storage navigator.


Indicate the duration (in minutes) for which this test should wait for a response from the storage device. By default, this is set to 5 minutes.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Operating rate

Indicates the speed, in percentage, with which this drive processes read/write requests.


A high value for this measure indicates that a large number of read/write operations have been performed on this drive. Comparing the value of this measure across drives will enable you to detect issues in load balancing across drives, accurately identify overloaded drives, and initiate relevant remedial measures.

Tag count

Indicates the maximum number of tags made on this drive per second.
