Upgrading the Subsystem

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 a specific logical block numbers (LBNs) on a
source disk drive configured as a unit on the same controller. Upgrading firmware on a
disk is a two-step process (see Figure 5–4).
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 has been 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 will not prevent this—but if the
upgrade fails, the device might be rendered unusable and therefore require the
manufacturer's attention.
• If the power fails or the bus is reset while HSUTIL is installing the new firmware,
the device might 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.
