only; no hard limits are enforced on storage capacity as a result of setting this value. The warning

is visible in these places:

• A yellow warning icon appears on the application component, user-defined application, or

shared folder icon in the content pane.

• As an alert in the Properties window.

NOTE: For shared folders and local storage applications, you can set an enforceable limit (or

quota) for allocated storage, as well as a warning threshold. For more information, see “Enforcing

an allocated storage limit for shared folders and local storage applications” (page 22).

Enforcing an allocated storage limit for shared folders and local storage applications

ASM provides a way to enforce an allocated storage limit for shared folders and local storage

applications. If enforced, the system does not allow the amount of allocated space for a shared

folder and local storage application to be exceeded.

If the capacity of the shared folder and/or local storage application surpasses the percent full

warning threshold and reaches the allocated space limit, the status changes from Warning to

Critical in the content pane, and users are blocked from adding data to the shared folder and

local storage application.

ASM does not support enforcing an allocated storage limit (or quota) for parent folders of shared

folders that are created and managed using ASM.

NOTE: If you do not choose to enforce an allocated storage limit for a shared folder, the ASM

status indicator still goes from Warning to Critical in the content pane; however, users are not

blocked from adding data to the shared folder as long as there is still unallocated storage space

on the logical disk where the shared folder resides. Data can be written to the shared folder until

the logical disk is full.

By default, the Enforce Allocated Limit (Quota) is set to No for all shared folders and local storage

applications. To change this setting, do one of the following:

• Using the Create a Shared Folder Wizard, change the Enforce Allocated Limit (Quota) setting

on the Advanced window to Yes.

• Select the shared folder in the content pane, click Properties in the Actions pane, click the

Warning Threshold tab, and then select the Enforce Allocated Limit (Quota).

NOTE: If a Shared Folder is created outside of ASM, you must use the Warning Threshold property

tab on the particular folder to enable the Enforce Allocated Limit (Quota) setting.

To allocate space for a shared folder, specify a size using the Allocate Space Wizard as described

in “Increasing or reducing the allocated storage” (page 33).

Selecting data protection

Use the Data Protection window in the wizard to select the following:

• Snapshots (Local disk backup) Previous versions of data are retained on disk using virtual

library backups and/or volume snapshots for fast recovery. See “Scheduling snapshots”

(page 23) for more information.

• Tape or Other Device (Alternate location backup) Data is copied off of this HP Storage System

to tape, other disks, or other types of storage media. This enables long term storage and

disaster recovery. See “Scheduling backups” (page 23) for more information.

From this window, you can also click Modify advanced properties to configure advanced settings

for backups.
