Adding Disks to a Storage Center System
As data is written, you will need to add disks or enclosures to the system. The supported
maximum number of enclosures attached to a Storage Center system depends on the type
of enclosure.
After disks are added to a system, space may not be immediately available. Make sure that
you allow enough time for the system to allocate space to use for writes.
Make sure you have disks available in sufficient time to incorporated them into the Storage
Center as needed.

To add disks to a Storage Center
1 Install enclosures and disk drives according to the hardware installation manuals,
shipped with these units. For more information about adding enclosures, refer to the
Storage Center System Connectivity Guide.
2 Once disks have been added, from the System Manager Storage Management menu,
select Disk > Scan for Disks. Storage Center scans for disks.
3 Data cannot be written to unmanaged disks. When disks are added to the Storage
Center system, the unmanaged disks appear in the Unassigned disk folder. If there are
no unassigned disks, the Unassigned disk folder disappears. An assigned disk folder
was created when the system was set up. (Refer to Storage Center System Setup
Guide.) Managing unassigned disks means to move them into a managed disk folder.
Create a new disk folder only to address specific application requirements. Creating a
second disk folder causes storage to be used less efficiently.
