Easiest way is to do it remotely. First, get the package from IBM, then copy the file to some directory. Then do the following:
chmod 755 ibm_fw_imm_yuoo*
./ibm_fw_imm_yuoo48d_linux_32-64.bin -x .
Now you have a bunch of files in this directory. This machine could be a laptop or whatever. Now you can remotely update the IMM as long as you are connected to it through the network.
./iflash64 –package imm_yuoo48d.upd –host i01-imm –user xcat –password f00bar
(Here, my host is the IP address of the IMM) Then my userid and password are there. )
The output is as follows:
IBM Command Line IMM Flash Update Utility v1.5

Connected to IMM at IP address 10.0.0.11.
Update package firmware type: IMM
Update package build level: YUOO48D
Target’s current build level: YUOO24H
Would you like to continue with the update? y/n: y
The IMM is preparing to receive the update.
Transferring image: 100%
Updating firmware: 100%
You’ll then need to wait a few seconds for it to become reactivated.
Note: Adding the -s flag will make it so that you are not prompted and works for doing lots of them.
