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.
Resizing the file system to match the new partition size is not automatic. It
may be necessary to expand or contract the file-system using tools specific to
your operating system.
In addition, in order to use the new capacity, you need to either resize the
existing partition or add a new partition.
Note: This step can only be done after the system has completed
the migration or online capacity process. The operating system will
not see the capacity until that process is complete.
To inform the operating system that secondary storage has been
upgraded:
1 If you change the configuration of the boot unit (the unit containing the
operating system), you must reboot the system in order to see the new unit
capacity.
2 Unmount all file systems.
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, from a command prompt, type
sync
<enter>,
sync
<enter>,
sync
<enter>.
You can then unmount the unit with this command: umount
<mount
location>
3 If the reconfigured unit is secondary storage, you must have the controller
rescan, in order to update unit information.
d In 3DM2, select the appropriate unit and choose Management >
Maintenance . Click the Remove Unit button.
e 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.
In 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.
