3–12 Compaq StorageWorks HSG80 Array Controller ACS Version 8.5 Maintenance and Service Guide
■ 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 (see
HSG80 Array Controller ACS Version 8.5 Configuration Guide .
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
The following menu appears:
