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 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.

To remove a drive

1 | In 3DM 2, 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 .

3 | When 3DM 2 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.
