HP StorageWorks X1000 Automated Storage Manager user guide (572087-001, June 2009)

The storage value for each application hosted, the shared folders pool, unallocated storage, and data
not managed by ASM is displayed according to its percentage of total capacity, using colors selected
in the Color Options window.
The total capacity of your HP Storage System is divided into the following areas:
• Exchange—Storage allocated to host Exchange storage group components.
• Shared Folders—Storage allocated to host shared folders.
• SQL Server—Storage allocated to host SQL Server database components.
• User-defined—Storage allocated to host user-defined applications.
• Data Protection — Storage allocated to host snapshots, backups, and replicated data.
• Unallocated—Unused storage that is not allocated.
The unallocated space value is the total unused space on your HP Storage System that has not
been allocated to host application or shared folder storage. Unallocated storage includes raw
(unconfigured) storage and unused configured storage (logical disks).
• Unmanaged—Storage used by data that is not managed by ASM.
The unmanaged value is the total storage being used to store data not managed by ASM, such
as application or shared folder data no longer managed by ASM because the application com-
ponents or shared folder was removed from view (see
“Removing application areas from view” on page 44) and any other data saved on your HP
Storage System that is not managed by ASM.
NOTE:
Logical disks (LUNs) being used to store application data or shared folders cannot be grown (increased
in size) by ASM using space on unused logical disks (configured storage); they can only be grown
using raw storage.
Unused logical disks are reallocated by ASM when an unhosted application component, shared
folder, or user-defined application's storage is hosted using a storage-allocation wizard and the
advanced configuration settings selected in the wizard match those of the unused logical disk. You
can find the advanced configuration settings and capacities of unused (and used) logical disks on the
Properties window for each logical disk (see Accessing properties for HP Storage System logical
disks on page 61).
Automated Storage Manager Alerts
ASM generates an alert when the status of an application area or storage area changes from OK to
Warning or Critical. The alerts describe the condition that caused the storage status to change. When
an alert is generated, a One or more alerts exist message appears in the ASM content pane. Click
the message to display a list of current ASM alerts.
NOTE:
ASM rolls up any status alert to the highest level. For instance, if a shared folder has surpassed its
percent full warning threshold and exceeded its allocated storage space, a warning icon is shown
on the shared folders pool icon. Likewise, if a critical status exists in an Exchange mail store, the
critical icon is also shown on the Exchange storage group icon.
