6.7 Firmware Upgrade
Step 1 :
From the host server, identify the SCSI devices that are associated with the 2U24 Flash Storage
Platform ESMs.
Note:
The operating system associates each SEP device as a SCSI device. The
SCSI device of the SEP can be used to get status from or control elements
within the enclosure.
a.
Issue the following command:
sg_scan -s | findstr /i encl
b.
Identify the SCSI devices from the output. The device information follows
SCSI0
. The
devices appear as
SCSI0:1,62,0
and
SCSI0:1,124,0
bolded in the example below.
SCSI0:1,62,0 claimed=0 pdt=dh HGST 2U24_STOR_ENCL
0428
SCSI0:1,124,0 claimed=0 pdt=dh HGST 2U24_STOR_ENCL
0428
Step 2 :
Upgrade the firmware using hgst_upg_tool.exe.
a.
The hgst_upg_tool.exe initiates the upgrade of the firmware one ESM at a time using
a specific SCSI device. Follow the key below to define the specific information that is
needed to complete the firmware download command for hgst_upg_tool.exe. The
command will be utilized to complete the upgrade on each ESM by executing the
command on the first SCSI device and then the second SCSI device.
hgst_upg_tool.exe -d SCSI0:
<devicenumber>
-f
<firmwareimage>
.bin -m 7
•
-d
is where the specific SCSI device is defined. This is located using an sg_scan
command that will provide two devices numbers. Insert the device number in
place of
<devicenumber>
.
•
-f
is where the filename of the firmware image is defined. This is the filename of
the firmware update that was downloaded from the Western Digital Support site.
Insert the filename in place of
<firmwareimage>
.
•
-m
is where the download microcode mode with offsets, save, and activate is
defined. For this case, the download microcode mode is predefined as mode
select 7.
b.
Issue the following command to upgrade ESM A using the first SCSI device:
hgst_upg_tool.exe -d SCSI0:<devicenumber> -f <firmwareimage>.bin -m 7
c.
Verify the status of the upgrade has completed before completing the next step.
d.
Check the Path States of the MPIO by clicking on the properties of one of the Multi-Path
Disk Devices and select the MPIO tab.
