The (controller, interconnect card) firmware upgrade on StorEdge 6120

You may need to do this one day, and this doc can help you, although you probably will find README file that comes with firmware (as patch).  

Assumption is that 6120 have Ethernet connection, since you need to copy files from management host. 

So the latest firmware for 6120 is 3.2.7. 

Verify on 6120 that you really need upgrade (maybe you already have 3.2.7) 
# ver 

Okay, say, you have 3.2.2 and do need upgrade!

Get the patch 116931-23 from Sun.
Gunzip and untar it and go to patch directory.   

Install the package SUNWc6120.
# pkgadd -d . SUNWc6120

Verify package: 
# pkginfo SUNWc6120
firmware    SUNWc6120 Sun StorEdge (tm) 6120 Array Firmware

Sun tries to make your life easier with script that ftp to 6120 and copy all necessary files there. Cool, why not, should be used. But say, you want manually to do this, basically most important files to copy on 6120 are: t4l2_327.bin (firmware level 2) t4l3_327.bin (firmware level 3 is actual application) lpc14_7.23.bin (firmware for interconnect card) Note: there are 3 levels of firmware, first one can be ignored, below is upgrade of levels 2 and 3. Upgrade firmware level 2 - loaded firmware into controller's EPROM.

Upgrade firmware for interconnect card (in my case, I have 2 arrays, so need to repeat this for u1l1, u1l2, u2l1 and u2l2.
# lpc download u1l1 lpc14_7.23.bin
Start Downloading Image ..............
Interconnect cards must be rebooted. # lpc reboot u2l1 Reset system to make sure it will boot properly. # reset -y

Disk firmware upgrade

This is simple, get required patch from Sun, unzip, untar (on management host) and look for the file, something like MAT3300F.1403.fw. Copy this (using ftp) to 6120. 

In this example, Fujitsu 300G disk will have firmware upgraded. 
# disk download u2d14 MAT3300F.1403.fw
u2d14 : disk firmware download pass
And this is it. One suggestion, please try to use Sun branded disk, otherwise they can cause trouble. Trust me. Disk FUJITSU MAT3300FC firmware version 0108 was causing my 6120 to repeatedly reboot.
