Step 2 : Type the sg_scan -i command to verify that the enclosure has been found by the server.
Step 3 : 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.
a. IMPORTANT: There is a firmware upgrade requirement which requires both Ethernet
interfaces interface to be connected and obtain IP addresses via DHCP prior to starting
the upgrade process. The Ethernet ports are shown in the following image:

# sg_scan -i | grep -i 4060 -B 1
<dev>: scsi8 channel=0 id=50 lun=0
HGST H4060-J 2020 [rmb=0 cmdq=1 pqual=0 pdev=0xd]
<dev>: scsi8 channel=0 id=204 lun=0
HGST H4060-J 2020 [rmb=0 cmdq=1 pqual=0 pdev=0xd]
Note: If the Ultrastar Data60 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 Data60
to a host that does expose the Enclosure Services Processor so that the
upgrade may be performed.
Attention: Beginning with firmware version 2000-073, the user may
upgrade in-band via sg_ses_microcode without the requirement
of having Ethernet interfaces actively configured with DHCP. Please
proceed to the upgrade procedure.
