Ensure Drive Integrity - ATTO Technology FastStream SC 5700 Installation And Operation Manual

The ATTO FastStream initialize and verify drive feature discovers and re-maps bad sectors on drives providing
reliable media for your RAID groups.
Before creating any RAID group you should initialize
and verify the drives selected to be in the RAID group
to ensure drive integrity. When selected, the
FastStream writes a pattern to the entire drive,
verifying the drive's readiness and reliability.
CAUTION CAUTION
Selecting Drive Initialization causes all
previous storage data on the drive to be
erased. Make sure all of your information is
backed up before initializing drives.
During initialization and verification, the FastStream
collects performance measurements. Performance
data is available once initialization begins. You may
view it from the Drive Performance and Health
page accessible from the Diagnostics menu. This
performance data is lost when the appliance is
powered off.

ATTO Technology Inc. FastStream SC Installation and Operation Manual

3.0 Ensure Drive Integrity

If you do not want to initialize or verify drives now,
continue on to Configure Storage into RAID Groups
on page 13.
You may check drive integrity after you have created
RAID groups on drives in RAID groups or drives which
you wish to add to your FastStream configuring using
the initialize and verify procedure or using a read-only
scan of drives.
The read-only drive test performs a non-destructive
scan over the entire surface of each drive to identify
bad areas of 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.
All eligible drives are highlighted in green; the
system only initializes highlighted drives.
Click Commit .
