multipath -ll | grep -i "active ready running" -c
Step 2 : Locate the <dev> device name from the sg_scan -i.
Step 3 : In the terminal, type:
sg_ses_microcode <dev> -m 0xe -N -b 4096 -I <filename> -vv
Step 4 : Press Enter.
The firmware begins loading onto the IOMs. The upgrade can take up to 20 minutes to

Important: Do not unzip/extract the tar.gz file. Doing so will result in errors during
the firmware upgrade process.
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 status of this process,
use the Redfish out-of-band management to make a GET request to the following
target:
curl -G
-k -u admin:admin -H "Content-type: application/
json" https://<ip address>/redfish/v1/UpdateService/Actions/
