Removing a Unit Through 3DM

In 3DM, the command for deleting a unit is on the Maintenance page. Be

sure to follow steps 1 and 2 in the instructions before using the Remove

command.

To remove a unit through 3DM 2

1 Make sure the operating system is not accessing the unit you want to

remove.

For example, make sure you are not copying files to the unit, and make

sure that there are no applications with open files on that unit.

2 Unmount the unit.

This step is very important. If a unit is not unmounted and you remove

it, it is the equivalent of physically yanking a hard drive out from under

the operating system. You could lose data, the system could hang, or the

controller could reset.

Under Windows, go to

Start > Administrative Tools > Computer

Management

, and select Disk Management. Remove the logical drive

letter for the unit.

Under Linux, you can unmount the unit with this command:

umount <mount location>

3 In 3DM 2, choose

Management > Maintenance.

4In the

Unit Maintenance table on the Maintenance page, select the unit

you want to remove and click

Remove Unit.

5 When a message asks you to confirm, click OK.

The unit number and information is removed from the

Maintenance page

in 3DM 2.

The operating system is notified that the unit was removed. In Linux the

device node associated with this unit is removed. In Windows the Device

Manager will reflect the changes under the disk drives icon.

You can now physically remove the drives and move them to another

controller. If the drive is in a hot swap bay, you can do this without

shutting down the system. If the drive is not in a hot swap bay, power-

down the system and ground yourself before making changes to the

hardware.

Note: If your drives are not in hot swap bays, you do not need to

remove a unit via 3DM. Simply power down the system and remove

the applicable drives. Refer to your system’s user guide for details on

removing fixed disks. If your drives are in hot swap bays, follow the

steps below.
