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. 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. 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" on page 97. 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 on page 82 for more information. • Tape or Other Device (Alternate location backup) Data is copied off of this All-in-One Storage System to tape, other disks, or other types of storage media. This enables long term storage and disaster recovery. See Scheduling backups on page 83 for more information. HP StorageWorks All-in-One Storage System 81
