b.
After connecting the Ethernet interfaces and obtaining the IP addresses via DHCP, locate
the
<dev>
device name from the
sg_scan -i
c.
Verify that both OOBMs have IP addresses by issuing the command
sg_ses <dev> -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>
Element 0 descriptor: ESCE IOMA,IOM PART NUM ,IOM SERIAL
NUM,5000CCAB0500003C,XXX.XXX.XXX.XXX

Linux Upgrade to New Firmware
To download the new firmware package, do the following:
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 :
In the terminal, type:
sg_ses_microcode <dev> -m 0xe -N -b 4096 -I <filename> -vv
Important:
Do not unzip/extract the tar.gz file. Doing so will result in errors during
the firmware upgrade process.
Step 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 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
