5.1.5 Windows Upgrade Preparation
To upgrade firmware using a windows server, do the following:
Step 1 : Make sure that sg3_utils is installed on the system and that the MPIO software is configured and
enabled on the host to be able to handle an online upgrade.
Step 2 : Connect the Ultrastar Data102 to a standard SAS HBA or a RAID SAS HBA hosted on the
Windows Server that presents the Enclosure Services Processor to the operating system. The
Enclosure Services Processor in the Ultrastar Data102 will be referred to as an IOM.
Step 3 : Log on to the Windows server and launch a command prompt.
Step 4 : Input the sg_scan -s command to find the IOM devices to ensure that they can be accessed.
Step 5 : To determine which IOM is which, use the <dev> string with the sg_ses command.
Step 6 : The following upgrade preparation steps apply only to firmware versions 01XX-XXX or if the
user is upgrading via OOBM. If this does not apply, please proceed to the upgrade procedure.
Note: To perform an online firmware upgrade, the Ultrastar Data102 must
be configured with redundant data paths, meaning both IOMs must have
a SAS Port populated and connected to the host server.
SAS Configurations: The server host must be configured with multi-
pathing software that can handle the nature of the firmware upgrade.
i.e. Once firmware is downloaded to the IOMs, each IOM will reset and
boot the new code in a staggered fashion such that the host always has
at least one path to the drives to service I/O.
SATA Configurations: A SATA configuration should not be considered for
an online upgrade due to the single path nature of the topology.

Requirement
Note: If the Ultrastar Data102 is connected to an HBA that does not
present the Enclosure Services Processor to the host for management
purposes, Western Digital recommends attaching the Ultrastar Data102
to a host that does expose the Enclosure Services Processor so that the
upgrade may be performed.
