a) IMPORTANT: There is a firmware upgrade requirement which requires both Ethernet interfaces be
connected and obtain IP addresses via DHCP prior to starting the upgrade process. The Ethernet ports
are shown in the following image:

b) After connecting both Ethernet interfaces and obtaining IP addresses via DHCP, locate the SCSIX:X,X,X
device name from the sg_scan -i output from step 2.
c) Verify that both OOBMs have IP addresses by issuing the command sg_ses SCSIX:X,X,X -p0x7
d) Locate the IP addresses in the Enclosure Services Controller Electronics (ESCE) elements, indicated
by the XXX.XXX.XXX.XXX in the results as shown in the following example:
Element type: Enclosure services controller electronics, subenclosure id: 0 [ti=5]
Overall descriptor: <empty>

Linux Upgrade to New Firmware
To download the new firmware package, do the following:
1. Ensure multi-pathing can see all of the expected drives.
a) Execute the following command to verify that there are two paths to each drive:
multipath -ll | grep -i “active ready running” -c
2. Locate the /dev/sgX device name from the sg_scan -i.
3. In the terminal, type:
sg_ses_microcode /dev/sgX -m 0xe -N -b 4096 -I <filename> -vv
4. Press Enter.
The firmware begins loading onto the IOMs. The upgrade can take up to 20 minutes to complete.
Important:
Due to the firmware image being a .tar.gz file, the enclosure has to unpack and load the firmware
onto the respective ICs which may take up to 15 minutes. Once the sg_ses_microcode command
is issued wait 20 minutes to ensure the enclosure has time to perform this process. To check the
