DuraStor 6220SS/7220SS Installation and User’s Guide
Changing Your Drive Configuration
You may need to change your storage subsystem from one drive
configuration to another or add another RAID controller to expand
your storage subsystem capabilities and capacity.
The DuraStor 6200S RAID controller features
drive roaming.
Drive
roaming allows RAID controllers to keep track of which disk drive
belongs to which logical array if the enclosure is changed or the
disk drive is moved.
To change to a new drive configuration, follow the setup
instructions for that configuration as provided in
Connecting the
SCSI RAID Appliance to the DuraStor 312R
on page 3-12
.
Note:
You will not be required to move disk drives around
in the enclosure. Drive roaming will locate those disk
drives when the DuraStor Storage Subsystem is powered
on.
Changing Your Operating Mode
To change to a new operating mode, follow the setup instructions
for that mode as provided in
Connecting the SCSI RAID Appliance to
the Host System
on page 3-17
.
Setting the Host System HBA to Multiple-LUN Support
Before your host system will recognize the arrays you create, you
must set the host system HBA to multiple-LUN support status.
1
Open your host system HBA BIOS. (Refer to your HBA
documentation for instructions on how to do this.)
2
Set Multiple LUN Support for controller ID (default
1
) to
Yes
.
3

documentation for instructions on how to do this.)
