Removing a Drive 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. To add a drive 1 Insert the drive into the hot swap bay or into your enclosure. 2 In 3DM, 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 113. 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 nonredundant 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 136. If you physically remove a drive on a 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. Drives that are part of a non-redundant or degraded unit cannot be removed. www.3ware.com 143
