HMC Upgrade using network images

HMC Upgrade using network images

01. Download the appropriate HMC V7 network images and put them on an FTP server.

02. Verify that the following files have been downloaded:

 initrd.gz, bzImage, disk1.img, disk2.img, and disk3.img

03. On the HMC, you must first save upgrade data by running the following commands:

   3a. To save data to both DVD and disk:
        mount /media/cdrom
        saveupgdata -r diskdvd
   3b. To save to disk alone:
        saveupgdata -r disk

04. Next, copy the files over to the bootable disk partition on the HMC from FTP server

    4a. getupgfiles -h remote_hostname  -u --passwd -d
    Note: use -s to use sftp instead of ftp.
    4b. If you want to see the progress of copy process, run the following command
    while true; do ls -la /hmcdump; sleep 30; done

05. After the files are copied over, run the following command:

    chhmc -c altdiskboot -s enable --mode upgrade

    Now the HMC is ready to be rebooted and automatically upgraded with the code copied to the bootable disk partition.

06. Finally, reboot the HMC and start the upgrade.

    hmcshutdown -r -t now
