2–24Configuring an HSZ80 Array Controller

UPS Support

NOTE: By default, the controller expects to use an external cache battery (ECB) as backup power to the cache module. You can instead choose to use an uninterruptable power supply (UPS) to provide backup power in the event of a primary power failure.

Use the following command:

SET THIS_CONTROLLER CACHE_UPS

If you are configuring dual-redundant controllers, also indicate that the other controller’s power is supported by a UPS. Use the following command:

SET OTHER_CONTROLLER CACHE_UPS

The other controller inherits the cache UPS setting for this controller.

See “SET controller” in Chapter 5, “CLI Commands,” for details about setting the UPS.

See Table 1–8 on page 1–23and Table 1–9 on page 1–25 for information about cache policies.
