Upgrading the Subsystem 6–11
Upgrading Firmware on a Device
Use HSUTIL to upgrade a device with firmware located in contiguous
blocks at a specific LBN on a source disk drive configured as a unit on
the same controller. Upgrading firmware on a disk is a two-step process
as shown in Figure 6–2: first, copy the new firmware from your host to
a disk drive configured as a unit in your subsystem, then use HSUTIL
to load the firmware onto the devices in the subsystem.
Figure 6–2 Upgrading Device Firmware
Keep the following points in mind while using HSUTIL to upgrade
firmware on a device:
n HSUTIL has been tested with the qualified devices listed in the
product-specific release notes that accompanied the software
release. You may attempt to install firmware on unsupported
devices—HSUTIL won’t prevent this—but if the upgrade fails, the
device may be rendered unusable and therefore require the
manufacturer’s attention.
n If the power fails or the bus is reset while HSUTIL is installing the
new firmware, the device may become unusable. To minimize this
possibility, DIGITAL recommends that you secure a reliable power
source and suspend all I/O to the bus that services the device you’re
upgrading.
