Chapter 7. Configuring Units
126 3ware SATA+SAS RAID Controller Card Software User Guide, Version 10.2
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 FreeBSD, you can unmount the unit with this command:
umount <mount location>
• Under Linux, you can unmount the unit with this command:
umount <mount location>
• Under Mac OS, launch the Macintosh Disk Utility, select the unit,
and click the Unmount button the toolbar, or select the icon for the
unit on the desktop and drag it to the trash.
• Under OpenSolaris, please consult your system documentation and
the LSI KnowledgeBase for more information.
• Under Windows, go to
Start >> Administrative Tools >> Computer
Management
, and select Disk Management. Remove the logical
drive letter for the unit. (under Windows it is not necessary to
unmount the device before deleting the unit, because the API code
correctly does this for you.)
• Under VMware, please consult your system documentation and the
LSI KnowledgeBase for more information.
3 In 3DM2, 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 3DM2.
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.
If you change your mind before physically removing the drives and want
to reuse the drives and unit on the current controller, just click
Rescan
Controller.
