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.

| 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.
If you physically remove a drive on a controller without first removing it in 3DM2, 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.

To remove a drive

1 | In 3DM2, choose Management >> Maintenance.

On the Maintenance page, Remove Drive 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 Remove Drive link .

Show Removing a Drive in 3DM2

3 | When 3DM2 asks you to confirm that you want to remove the drive, click OK.

You can now remove the drive from your system.
If you removed a drive that was part of a unit, the unit will become degraded, as shown in the screenshot below.
