HP StorageWorks 2405 Disk System - Manual (Page 16)

16 Product Description
Upgradability
You can increase disk system storage capacity by:
■ Replacing disk drives with higher-capacity disk drives
■ Adding disks in unused slots
■ Adding another disk system to a FC loop
None of these actions require shutting down the product, but some may require
the use of system utilities to manage file systems.
Disk and LCC firmware is downloadable using the supported tools.
Environmental Services
Environmental services circuitry monitors the following elements:
■ Fan rotation
■ Power supply output
■ Power supply and fan status
■ Disk drive status, including fault conditions
■ LCC status
■ Temperature
■ Self-test results
Each LCC reports the status of all elements in the disk system, even if the LCC
does not have direct access to the element.
Additionally, the EEPROM on each LCC stores 2 Kbytes of configuration
information and user-defined data, including the manufacturer serial number and
product number.
