2. Connect the Ultrastar Data60 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 Data60 will be referred to as an IOM.
Note: To perform an online firmware upgrade, the Ultrastar Data60 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.

3. Log on to the Windows server and launch a command prompt.
4. Input the sg_scan -s command to find the IOM devices to ensure that they can be accessed.
Note: If the Ultrastar Data60 is connected to an HBA that does not present the Enclosure Services
Processor to the host for management purposes, HGST recommends attaching the Ultrastar Data60
to a host that does expose the Enclosure Services Processor so that the upgrade may be performed.
5. To determine which IOM is which, use the SCSIX: X,X,X string with the sg_ses command.
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.
