Configuring Units

136 3ware SATA+SAS RAID Controller Card Software User Guide, Version 10.0

To add a drive

1 Insert the drive into the hot swap bay or into your enclosure.

For details, refer to the documentation for your enclosure.

2 In 3DM 2, choose

Management > Maintenance.

3 On the Maintenance page, click

Rescan Controller.

The drive will appear in the list of available drives. You can now use it in

a new RAID configuration, as part of an existing configuration, or as a

replacement drive in the event that another drive degrades.

If you want to use this drive as a spare, see “Creating a Hot Spare” on

page 104.

Removing a Drive

If you have hot swappable drives in a carrier or an enclosure and you want to

physically remove a drive from your system without powering it down, you

should first remove it through the 3ware software.

Follow this procedure if you know that a drive is developing a problem and

you want to replace it, or to replace a drive which has already failed.

Note: When you add a drive to your system and connect it to the controller, it is

automatically detected and listed in 3DM. If it does not immediately display, or if it is

part of a unit, you can use the rescan feature, as described below.

Warnings:

Physically removing a drive that is not in a hot swap bay or that is part of a non-

redundant unit, can result in a system hang or may even damage the system and

the drive.

The steps below will destroy any information that identifies this drive as part of a

RAID unit.

Existing data on this drive will no longer be available.

Notes:

If you want to remove a unit from your system and reassemble it in another system,

do not follow these steps. Instead, turn to “Removing a Unit” on page 131.

If you physically remove a drive on a controller without first removing it in 3DM 2, it

will be listed as removed, however it will not be completely removed unless you

Rescan the controller.

Drives that are part of a non-redundant or degraded unit cannot be removed.
