HP Array Controller HSG V8.7 Software - Manual (Page 258)

6–12 HSG80 User’s Guide
n 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.
n During the installation, the source disk drive is not available for
other subsystem operations.
n 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.
n 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 “SET unit-number,” page B–137).
See “Configuring a Single-Disk Unit,” page 3–60, for instructions on
configuring a single-disk unit.
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.
