Upgrading HMC from remote location by using network upgrade images

Learn how to upgrade the software on an HMC from a remote location by using network upgrade images.

1. From a computer or server with an internet connection, go to the Hardware Management Console Support and downloads website (http://www14.software.ibm.com/webapp/set2/sas/f/hmcl/home.html).
2. Download the appropriate HMC V9 network images and save them on an FTP server.
   You cannot download these files directly to the HMC. You must download the image files to a server that accepts FTP requests.
3. Ensure that you download the following files:
   • img2a
   • img3a
   • base.img
   • disk1.img
   • hmcnetworkfiles.sum
4. Save the upgrade data on the HMC. Run the following commands to save the upgrade data:
   • To save data on both DVD and HDD, run the following commands:

     mount /media/cdrom

     saveupgdata -r diskdvd

   • To save data on the HDD, run the following command:

     saveupgdata -r disk

5. Copy the upgrade files to the bootable disk partition on the HMC. Run the getupgfiles command to copy the files.

   Example: getupgfiles -h <ftp server> -u <user id> -d <remote directory>

   Where,

   • ftp server is the host name or IP address of the FTP server where you download the HMC network images.
   • user id is a valid user ID on the FTP server. If you do not specify the password with the --passwd argument, you are prompted for a password.
   • remote directory is the directory on your FTP server where the HMC network images are saved.
6. Restart the HMC to upgrade the code that is copied to the bootable disk partition. Run the chhmc -c altdiskboot -s enable --mode upgrade to restart the HMC.
7. Restart the HMC and start the upgrade. Run the hmcshutdown -r -t now command to start the upgrade.
