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 “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.
