5.1.2 Linux Upgrade Preparation
To prepare the firmware package for download, do the following:
Step 1 : Connect the Ultrastar Data60 to a standard SAS HBA or a RAID SAS HBA hosted on the Linux
Server that presents the Enclosure Services Processor to the Linux 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.
