Below is an output from the Equallogic firmware update process from 7.1.14 to 8.1.6. In this example I will be using FTP to transfer the file (kit_V8.1.6-R427114_2004107431.tgz) to the member (not group) and updating via the CLI
Group name: btn-eqlbackup-g1 (192.168.74.230)
Member name: BTN-EQL6000E-BP1 (192.168.74.231)
1) FTP firmware to member (192.168.74.231) ensuring binary mode is selected for transfer using grpadmin username.
2) Telnet or SSH to member using grpadmin username.
# telnet 192.168.74.231
3) Updating the firmware
btn-eqlbackup-g1> update
15:15:59 Updating from kit file “kit_V8.1.6-R427114_2004107431.tgz”
This command will install the update kit file that was
copied to the array.
If you choose to proceed, you will be shown the current firmware version
and the version to which you will update. You will then be given the
choice to proceed again.

There is new firmware in the update area.
As part of applying the new firmware, the active and secondary control
modules will switch roles. Therefore, the current active control module
will become the secondary after the firmware is applied.
Would you like to load the firmware now? (yes/no) [no] yes
