Upgrading the Subsystem
240 HP StorageWorks HSG60 and HSG80 Array Controller and Array Controller Software
Maintenance and Service Guide
■ 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
distributes 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: Quiesce the host load before running HSUTIL ; otherwise, damage to
the storage device can occur.
