Select this option to display the threshold and overflow values of the ASP and the assigned disk units. This display is also available under the Display disk configuration option (see “Display disk configuration” on page 18).

vDelete user ASP

Select this option to delete a user-defined ASP (ASPs 2 through 16).

vAdd units to ASPs

Select this option to add non-configured units to an existing ASP. This increases the amount of storage that is assigned to the system ASP (ASP 1).

vAdd units to ASPs and balance data

Select this option to add disk units to an existing ASP or to create an ASP and add non-configured disk units to that ASP.

After the disk units are initialized and configured, the data on the other disk units is moved to equally balance the capacity of all the disk units in the ASP.

vDelete ASP data

Select this option when you want to destroy the data in the ASP.

vChange ASP storage threshold

Select this option to display or change the threshold for the system auxiliary storage pool (user ASPs are not supported). The system notifies you when the threshold value is reached.

vMove units from one ASP to another

Select this option to change the assignment of a disk unit to another ASP.

vRemove units from configuration

Select this option to remove a disk unit from the ASP configuration. If the unit being removed has data and there is space in the ASP, the system copies the data to other units in the ASP. If there is not enough space in the ASP, the system prompts you to delete the ASP data before removing the disk unit. The unit that is removed becomes non-configured.

Attention: This is space-dependent. There must be enough space on the remaining units to accommodate the data from the unit being removed.

Work with mirrored protection: Select this option to display or change mirrored protection on the disk units.

vDisplay disk configuration

For details on this option, see the main heading, “Display disk configuration” on page 18.

vStart mirrored protection

This option allows you to start mirrored protection on the selected Auxiliary Storage Pool (ASP).

vStop mirrored protection

This option allows you to stop mirrored protection on the selected Auxiliary Storage Pool (ASP).

vEnable remote load-source mirroring

Select this option to turn on the ability to physically place the two units that make up the mirrored load-source disk unit (unit 1) on different input-output processors (IOP). This option does not start mirrored protection.

vDisable remote load-source mirroring

Select this option to turn off the ability to physically place the two units that make up the mirrored load-source disk unit (unit 1) on different IOPs. This option does not stop mirrored protection.
