AIX:HMC Remote Upgrade

Download the networkupgrade files

ftp
ftp> open ftp.software.ibm.com
  Name: anonymous
  Password: ftp
ftp> cd software/server/hmc/network/v7720
ftp> prompt   (turns off interacive mode)
ftp> bin   (ensures binary transfer mode)
ftp> mget *   (downloads all six files simultaneously)
ftp> bye   (exits FTP after all files have been downloaded)”

>saveupgdata -r disk

>getupgfiles -h ftp.software.ibm.com -u anonymous --passwd ftp -d /software/server/hmc/network/v7720

while true ; do
date
ls -la /hmcdump
sleep 60
done

Once the download completes, the /hmcdump filesystem gets unmounted. That tells you that the download is finished.

"The getupgfiles operation will mount a filesystem called /hmcdump and copy the install files into the directory then unmount the filesystem. The following commands will set the HMC to boot from the network install images and allow the upgrade to proceed."

Once the download is complete:

>chhmc -c altdiskboot -s enable --mode upgrade
>hmcshutdown -r -t now

And now we wait. This can take 20-50 minutes.
