ALOM Firmware Upgrade Method

As I mentioned in a previous post, I have been given a v240 to get prepped for a demo. The server needs a little TLC including a firmware upgrade, an OS upgrade and an ALOM upgrade. I have gotten the firmware and OS upgraded and now am working on the ALOM.

The readme in the file is pretty straight forward on the steps.

1. Use the telnet, rlogin or ssh command through the network to log into the system as superuser.
Caution: Do not attempt this procedure while logged into the system through the SERIAL MGT port.
2. Change directories as follows:
# cd /usr/platform/`uname -i`/lib
3. If there is no images subdirectory, create one:
# mkdir images
4. Change to the images directory:
# cd images
5. Place this file in the images directory:
ALOM_1.6.3_fw_hw0.tar.gz
6. Unpack the tar file: gzcat ALOM_1.6.3_fw_hw0.tar.gz | tar xf -
The following files will be created:
README (this file)
copyright
alombootfw (boot image file)
alommainfw (main image file)
7. Load the boot image file alombootfw into the System Controller hardware:
# /usr/platform/`uname -i`/sbin/scadm download boot alombootfw
8. When the scadm utility completes, wait 60 seconds.
9. Load the main image file alommainfw into the System Controller hardware:
# /usr/platform/`uname -i`/sbin/scadm download alommainfw
Approximately 120 seconds after the scadm utility completes, ALOM is available for use.
10. Delete the tar file:
# rm ALOM_1.6.3_fw_hw0.tar.gz

After a few minutes, I got a message back that the ALOM was upgraded. I connected to the ALOM and ran setupsc. One of the best features of the new ALOM version is that you can disable telnet and use ssh. My opinion about telnet can be found here. After a restart of the ALOM I can now ssh in

Update an OBP from a Solaris Shell

You can also update the OBP from a Solaris window (command line) if the UNIX update (.sh) file is included in the patch. Log in as root and cd to the patch directory, then run the executable UNIX flash update file by typing sh <unix.flash-update-filename.sh>. Follow instructions printed on the screen. Note: When it gives you the available upgrade versions, type sa to select them, then proceed per instructions. When the update is complete, the system should be rebooted and the new OBP will be active. 

Update an OBP from the OK Prompt

Copy the latest flash-update image to the / directory of the system to be updated and remember
the name of the file. Then go to the OK prompt with halt or init 0 or uadmin 2 0. At the OK prompt, type boot disk /<flash-update file name> and hit Return. Follow instructions printed on
the screen. Note: When it gives you the available upgrade versions, type sa to select them, then proceed per instructions. When
the update is complete, the system should be rebooted and the new OBP is active
