rebuilding RAID

To synchronize mirrored drives manually

The most efficient method to synchronize Virtual
Tape configurations is to enable Hot Spares or the
auto rebuild feature.

Connect to Diamond Storage Array services via
the RS-232 port or the optional Ethernet
management services card (see

Accessing the

Diamond-VT

on page 15). You should now be in

CLI.

Access the

RAID

page of the ExpressNAV

interface (see

ATTO ExpressNAV: Browser-based

Interface

on page 23).

Use the

VirtualDriveInfo

and

TapeVolumeInfo

commands to identify a Tape Volume associated
with the RAID group you wish to rebuild.

Go to the

Move Medium

page.

Drag the selected Tape Volume into an
unoccupied Tape Drive LUN.

From the CLI window, initiate a Rebuild operation
from the Tape Drive LUN to the desired Drive
Sled.

Note

When this rebuild operation has completed, the
entire RAID group will have been rebuilt,
effectively rebuilding all Tape Volumes
associated with the underlying RAID Group: you
do not need to rebuild each Tape Volume
separately.
