Upgrading firmware on a device
Use the format and device code load utility (HSUTIL) to upgrade a device with
firmware located in contiguous blocks at specific logical block numbers (LBNs)
on a source disk drive. The source disk drive must be configured as a unit on the
same controller. Upgrading firmware on a disk is a two-step process (see
Figure 120):
1. Copy the new firmware from the host to a disk drive configured as a unit in
the subsystem.
2. Use HSUTIL to load the firmware onto the devices in the subsystem.

Keep the following points in mind while using HSUTIL to upgrade firmware on a
device:
■ HSUTIL is tested with the qualified devices listed in the product-specific
release notes that accompanied the software release. Firmware installed on
unsupported devices is possible—HSUTIL does not prevent this—but if the
upgrade fails, the device might be rendered unusable and, therefore, require
manufacturer attention.
■ If the power fails or the bus is reset while HSUTIL is installing the new
firmware, the device can become unusable. To minimize this possibility,
secure a reliable power source and suspend all I/O to the bus that services the
device being upgraded.
