CAUTION!
To assure the safety of the data, please run a complete backup and verify
prior to beginning the following procedure. When changing any
configuration or adapter card there is always a danger of data loss.
Note:
You cannot reduce the capacity of an existing array; you can only expand
it. To reduce capacity, you must create a new array and copy the data from
the old array using your operating system’s copy function. You can then
delete the old array. See Deleting an Array on page 3-7.
You can only add drives to a stripe set (RAID 0) or RAID 5 set on systems
running Windows NT/2000 using the NTFS file system.
Any added drives must have sufficient free space for Storage Manager Pro
to create a properly sized partition for the array. Drives that do not
have any free space are not displayed in the Available Drives list in the
Reconfigure Array dialog box.
After you expand the size of the array, you must also use Disk
Administrator to make the additional space available to users.
To add drives:
1) In the System Browser window, select the array whose drives
you want to change.
2) Click Reconfigure.
The Reconfigure Array dialog box appears. The Selected
Drives list shows the current drives for the array.
3) Select the drives you want to add:
– To add drives, select one or more in the Available Drives
list and click Add Drive. The drives you selected move to
the Selected Drives list and display a yellow asterisk
showing that they are new drives for this array. See
Understanding the Selected Drive Icons on page 2-8.
– To add all available drives, click Add All Drives.
– To select more than one drive, hold the Ctrl key and click
each drive.
– See the Array Information section of the dialog box for
information about how much space will be used on each
drive.
Note:
CAUTION!
If you are adding drives to a RAID 5 set, your data will not be redundant
until the array expansion is completed and the array is back to a fault
tolerant condition.
CAUTION!
After the array has been expanded, the OS will also need to either
partition the additional space as a seperate volume or, if a single volume
is desired then, you must also use Disk Administrator to make the
additional space available, during the Volume expansion there is no fault
tolerance and if anything goes wrong, all data will be lost. |
