Informing the Operating System of Changed Configuration
After you change the configuration of a unit, you must inform the operating system of the change, and you may need to re-partition the unit.
The easiest way to see the change in capacity is to reboot the system. If you are not booted from the unit be sure the unit is not mounted and not in use. You should follow the specific operating system guide on how to unmount the volume. Then use 3DM2 or CLI to remove the unit. Then rescan so the operating system can recognize the new capacity.
In addition, in order to use the new capacity, you need to either resize the existing partition or add a new partition.
To inform the operating system that a unit has been changed

1 | If the unit you reconfigured is the boot unit, restart the system and skip to Step 3.

If the unit you reconfigured is secondary storage, unmount the file system from the unit.

| Under FreeBSD, from a command prompt, type sync <enter>, sync <enter>, sync <enter>.

You can then unmount the unit with this command: umount <mount location>

| Under Linux, from a command prompt, type sync <enter>, sync <enter>, sync <enter>.

You can then unmount the unit with this command: umount <mount location>

| Under Mac OS, Unmount the file system from the unit.

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 VMware, 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.

2 | In the software, remove and rescan the controller, in order to update unit information.

a | In 3DM2 choose Management >> Maintenance and select the appropriate unit.

b | Click the Remove Unit button.

c | After the unit has been removed, click the Rescan button. The new unit capacity displays.

4 | Resize the partition and file system or create a new partition.

Under Windows, use the disk management utility to determine whether the disk is a basic disk or a dynamic disk.

| Go to Administrative Tools >> Computer Management, and then select Disk Management in the list on the left.

Only dynamic disks can be expanded with Windows Disk Management. If the unit is shown as a basic disk, right-click on the disk icon and change it to a dynamic disk.
Older Windows systems cannot convert basic disks into dynamic disks after the file system has been created.

| If the unit is shown as a dynamic disk, right-click on it and choose Extend Volume to launch the Extend Volume wizard.

In other operating systems, the tools to expand the partition and file system can vary, depending on the kernel version and file system that you are using. Please consult your system documentation and the LSI KnowledgeBase for more information.
