• HSUTIL cannot install firmware on devices configured as single-disk drive units
or as members of a storageset, spareset, or failedset. If installing firmware on a
device previously configured as a single-disk drive, delete the unit number and
storageset name associated with it.
• During the installation, the source disk drive is not available for other subsystem
operations.
• Some devices might not reflect the new firmware version number when viewed
from the "other controller" in a dual-redundant controller configuration. If this
occurs, enter the following CLI command: CLEAR_ERRORS device-name
UNKNOWN.
• Do not issue any CLI commands that access or inspect devices that are being
formatted.
Use the following steps to upgrade firmware with HSUTIL.
1. Connect a PC or terminal to the controller maintenance port that accesses the
device being upgraded.
2. Configure a single-disk unit.
NOTE: In the next steps, the firmware image is copied to this unit and HSUTIL is used to
distribute it to the devices being upgraded. This unit must be a newly initialized disk with no
label or file structure to ensure that the firmware image resides in contiguous blocks
starting from LBN 0 or another known LBN. Additionally, write-back caching must be
disabled.
3. Copy the firmware image to the single-disk unit configured in step 2. The
firmware image must begin at a known LBN—usually 0—and must be
contiguous.
See the documentation that accompanied the host operating system for
instructions on copying firmware images to a disk drive.
CAUTION: The host load must be quiesced before running HSUTIL; otherwise,
damage to the storage device can occur.
4. Start HSUTIL with the following command:
RUN HSUTIL
