Configuring Units

134 3ware SATA+SAS RAID Controller Card Software User Guide, Version 10.0

3DM 2 includes two features that help you move a unit without powering

down the system, allowing you to hot swap the unit. The Remove Unit feature

lets you prepare a unit to be disconnected from the controller, and the Rescan

feature checks the controller for drives that are now connected, and updates

the 3DM 2 screens with current information. For details, see “Removing a

Unit” on page 131 and “Rescanning the Controller” on page 138.

Moving Units from an Earlier 9000 Series to a 9750

Controller

If you are moving units from a 9550SX or later 9000-series controller to a

9750 controller, the process is a little different from when you are moving

units from one 9750 to another.. The steps you follow depend on whether you

are booting from the drives attached to the older controller, or whether they

are being used for secondary storage.

To move a bootable unit from an earlier 9000 series controller to a

9750 controller

1 If you are working with a Linux system, skip to step 2.

If you are working with a Windows system:

a Power down the computer.

b Install the 9750 controller in the computer, leaving the original

controller installed and its drives attached.

c Boot to the operating system.

2 Install the driver for the 9750 RAID controller.

If you are using Linux, you may also need to update the initial RAM disk.

For more information, see “Updating the 3ware Driver Under Red Hat or

Fedora Core” on page 183 or “Updating the 3ware Driver Under SUSE”

on page 185.

3 Power down the computer.

Note: Moving a unit to another controller while the unit is in the migration state is

supported with one restriction. If the unit was in the middle of the migration process

and the controller was shutdown uncleanly, the unit cannot be moved to another

controller until the unit has recovered from the unclean shutdown. This may require

initializing, verifying, or rebuilding the unit.

Note: Only SATA-2 drives are supported on the 9750. You cannot move SATA-1

drives.
