Unmount A Volume; Remove A Volume; Update Drivers Across Volumes; Optimize Volumes With Mode Pages - ATTO Technology R30F Installation And Operation Manual

Selecting a drive in the device window and clicking the
mount button mounts all volumes created from that
drive. Unmounted volumes are marked with an
asterisk (*) before their names.

Unmount a Volume

Unmounting a volume removes its icon on the desktop,
but does not erase or change data on the volume in any
way. The volume cannot be accessed until it is
mounted again.
To unmount a volume
1 Select the volume from the volume window
by clicking on it
2 Select Unmount Volume from the Utilities
Menu or click the Unmount button.
Selecting a drive in the device window and clicking the
unmount button unmounts all volumes created from
that drive. Unmounted volumes have an asterisk (*)
before their names.

Remove a Volume

Removing a volume erases all data and volume
information it. The disk space used by the volume
becomes available space used for creating new
volumes.
To remove a volume
1 Highlight the volume in the volume window
2 Select Remove Volume from the Utilities
Menu.

Update drivers across volumes

For optimum system performance, all drives on a
system should use the same disk driver. The install
driver option allows you to install the ExpressRAID
driver on all drives without altering the volumes on the
drive.
To install the ExpressRAID Driver
1 Select the drive from the device window
2 Select Install Driver from the Utilities Menu.
CAUTION Back up all hard drives before installing a new
driver to prevent loss of data if errors occur.

Optimize volumes with mode pages

Mode pages are device-specific parameters stored on
the hard drive which control a variety of functions
including drive cache management, error detection
and error recovery.
To optimize a new volume for digital video or
prepress
1 Select Configure Mode Pages
11 ATTO Technology ExpressPro-Tools Installation and Operation Manual
2 Select Set for Video or Set for Prepress from
the Utilities Menu
ExpressRAID examines the drive and selects the
optimum mode page settings for digital video capture
and playback or prepress.
If you are not doing digital video or prepress work,
choose the drive's factory defaults.

Verify Mirrored Volume

Verifying a mirrored volume is useful when you
suspect a mirrored volume has been damaged. The
volume will highlight and flash. You will be informed
if the volume is repairable or not repairable.

Equalize Mirrored Volume

If a mirrored volume is damaged and appears to be
repairable, you can repair the damaged volume by
equalizing it, restoring all information to the damaged
drive.

Separate Mirrored Volume

When a damaged mirrored volume is unrecoverable,
you should separate the mirrored volumes, then run a
disk diagnostic program on each drive separately.
When you find the bad or damaged drive, you can
create a new mirror group with one of the good or
undamaged drives.

Non-ATTO LUNs Enabled
attached to third party host adapters to mount on your
desktop at boot time. If you create an ATTO volume
(RAID or non-RAID) on LUN(s), then the ATTO
driver will control those LUN(s).
Note: This applies to both zero and non-zero LUNs. At boot-
time, the ATTO driver will not scan for non-zero LUNs
unless the device is on an ATTO host adapter. If the disk at
LUN 0 has Non-ATTO LUNs Enabled, then the ATTO
driver will continue to scan LUNs at this ID.

ExpressWatch Build in Background (RAID1 only)

ExpressWatch runs continuously in the background to
monitor the status of RAID 1 volumes created by
ExpressRAID, and alerts you if a RAID member fails.
This means that when a RAID 1 group is first created,
all of the data on one disk (the source or primary disk)
must be copied (mirrored) to other, a time consuming
process with large volumes. However, you can do
