The following examples are the output of the lsmcode command for AIX 5L and Linux,
showing the firmware levels as they are displayed in the outputs:
AIX 5L
The current permanent system firmware image is SF220_005.
The current temporary system firmware image is SF220_006.
The system is currently booted from the temporary image.
Linux
system:SF220_006 (t) SF220_005 (p) SF220_006 (b)
When you install a server firmware fix, it is installed on the temporary side.
Note: The following points are of special interest:
The server firmware fix is installed on the temporary side only after the existing
contents of the temporary side are permanently installed on the permanent side (the
service processor performs this process automatically when you install a server
firmware fix).
If you want to preserve the contents of the permanent side, you need to remove the
current level of firmware (copy the contents of the permanent side to the temporary
side) before you install the fix.
However, if you get your fixes using the Advanced features on the HMC interface and
you indicate that you do not want the service processor to automatically accept the
firmware level, the contents of the temporary side are not automatically installed on the
permanent side. In this situation, you do not need to remove the current level of
firmware to preserve the contents of the permanent side before you install the fix.
You might want to use the new level of firmware for a period of time to verify that it works
correctly. When you are sure that the new level of firmware works correctly, you can
permanently install the server firmware fix. When you permanently install a server firmware
fix, you copy the temporary firmware level from the temporary side to the permanent side.
Conversely, if you decide that you do not want to keep the new level of server firmware, you
can remove the current level of firmware. When you remove the current level of firmware, you
copy the firmware level that is currently installed on the permanent side from the permanent
side to the temporary side.
