ATTO Technology SC 5700 operation manual Ensure Drive Integrity, Before creating RAID groups

3.0 Ensure Drive Integrity

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

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.

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.

CAUTION

Do not restart the FastStream or disconnect or power cycle drives during Drive Initialization and Verification or you must start the verification process from the beginning.
