Chapter 5. Configuring Units

58

Adding a Drive

You can add a drive to your 3ware Sidecar and make it available through 
3DM without powering down the system.

1

Insert the drive in your 3ware Sidecar. (For details, see 3ware Sidecar Kit 
with the 9590SE-ME: Installation Guide.)

2

In 3DM, choose 

. 

3

On the Maintenance page, click 

The drive will appear in the list of available drives. You can now use it in 
a new RAID 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 42.

Removing a Drive

If you want to physically remove a drive from your 3ware Sidecar without 
powering it down, you must first remove it through the 3ware software.

This is useful 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.

                                      

1

In 3DM, choose 

. 

On the Maintenance page, 

 links appear next to all drives 

that can be removed from units, and next to drives in the Available Drives 
list. 

2

Locate the drive you want to remove and click the 

 link 

 

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 56. 

If you physically remove a drive on a 9590SE controller without first removing it in 
3DM, it will be listed as removed, however it will not be completely removed unless 
you Rescan the controller.
