ATTO Technology Inc. FastStream SC Installation and Operation Manual
6.2 Drive Diagnostics
You may determine the performance of drives attached to the FastStream using various displays and tests in
ExpressNAV Storage Manager.
The following instructions assume you have already
set up at least one RAID group.
The ATTO FastStream collects various metrics to
measure performance for physical drives attached to
the FastStream during normal system operation and
drive initialization and verification.
New performance data is updated every 60 seconds
which impacts performance slightly, even if you
minimize the browser window. Exit the ExpressNAV
Storage Manager completely whenever you need
maximum performance.
Preliminary steps
1 If you are not already in the ExpressNAV
Storage Manager, type the IP address of your
appliance in a standard browser. On the splash
screen, click
Enter Here. In the box provided,
type in your user name and password, and click
OK.
2 The Health and Status Monitor page appears.
Click the Diagnostics button on the left hand
menu.
3 Select the operation you wish to perform from
the next menu presented.
Note
Identify SES Elements is not available for
the FastStream SC 5300 model.
Read only drive test
The read only test performs a non-destructive scan
over the entire surface of each drive to identify bad
areas of the disk drives and determine read
performance. It may be run while data is passing
through the FastStream.
Running this test may negatively impact performance.
Once the Read-only test has completed, system
operation returns to normal.
To fix errors on disks, use the Initialize and Verify
Drives process as described in
Ensure Drive Integrity
on page 11.
