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
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 and FreeBSD, you can unmount the unit with this command:
umount
3
In 3DM, choose
Management > Maintenance
.
4
In 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.
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.
