Step 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
Step 2 : Locate the <dev> device name from the sg_scan -i.
Step 3 : Execute the following command to upgrade the enclosure firmware using sg_ses_microcode.
a. Issue the following command:
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
complete.
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/
UpdateService.SimpleUpdate/Status
Note: Execute the command until you see the following result:
{"ErrorCode":0,"StatusCode":2,"Description":"FW update completed.
Waiting for activation.","EstimatedRemainingMinutes":0}
Attention: If the OOBM is not being used, query Page Eh by executing the
following command
sg_ses <dev> -p 0xe
the output may be inaccurate, please ignore and issue the command again. The
string to observe for download microcode status is "Complete, no error, start
after hard reset or power cycle [0x11]" before proceeding to the activate step.
Example output:
sg_ses <dev> -p 0xe
HGST H4102-J <FW Version>
