Compaq HSZ80 Array Controller ACS Version 8.3 Maintenance and Service Guide
■ HSUTIL cannot install firmware on devices that have been configured as single
disk drive units or as members of a storageset, spareset, or failedset. If you want
to install firmware on a device that has previously been 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 may not reflect the new firmware version number when viewed
from the “other” controller in a dual-redundant configuration. If you experience
this, 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 maintenance port on the controller that accesses
the device you want to upgrade.
2. Configure a single-disk unit.
NOTE: In the next steps, you’ll copy the firmware image to this unit, then use
HSUTIL to distribute it to the devices you’re upgrading. 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
HSZ80 ACS Version 8.3
Configuration and CLI Reference Guide
).
3. Copy the firmware image to the single-disk unit that you configured in step 2.
The firmware image must begin at a known LBN—usually 0—and must be
contiguous. See the documentation that accompanied your host’s operating
system for instructions on copying firmware images to a disk drive.
CAUTION: You must quiesce the host load before running HSUTIL or
damage to the storage device can occur.
4. Start HSUTIL with the following command:
RUN HSUTIL
