ATTO Technology Inc. FastStream SC 5700 Installation and Operation Manual
4.0 Modify storage
Use the ExpressNAV interface to replace a failed drive, add new drives or redesign RAID
configurations.
CAUTIONCAUTION
Clicking on Commit during RAID
configuration causes all previous storage
data on the drive to be erased. Ensure all
data is backed up.
You may modify various aspects of storage using
the Manage Menu found by clicking on the tab
on the left hand side of the ExpressNAV interface.
Be cautious when deleting storage or rearranging
storage configurations because data could be
compromised or lost.
The ExpressNAV interface takes you step by step
through many procedures which allow you to
modify your storage and RAID configurations.
Read all notes and cautions carefully as you go to
ensure the best performance and use of your
storage.
When you initially set up the FastStream, replace
a failed drive or add new drives to the FastStream,
perform drive initialization and verification to
these drives.
Many of these procedures are only available on
unallocated storage which is not currently part of
a RAID group, not designated as a Hot Spare, or
was offline when you initially set up RAID
configurations.
Initialize and verify drives
During initialization, the FastStream writes a
pattern to the entire drive. This operation attempts
to fix soft errors and reallocate bad blocks on
existing drives.
CAUTIONCAUTION
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.
