If you want to specify a resource dependency between 2 resources, one the parent and the other the child, to manage resource startup order, then you need an application monitoring.

• First download, and put on an ftp server, the latest version of the following files: initrd.gz, bzImage, disk1.img, disk2.img, and disk3.img

On the IBM Web site: http://www14.software.ibm.com/support/customercare/sas/f/netinstall/home.html

• Take a backup on disk of the datas needed for upgrade:

hscroot@HMC:~> saveupgdata -r disk

• Download on the HMC the file from ftp server, and reboot with upgrade:

hscroot@HMC:~> getupgfiles -h ftpserver -u ftpuser --passwd xxxxxx -d /soft/hmc 
hscroot@HMC:~> chhmc -c altdiskboot -s enable --mode upgrade
hscroot@HMC:~> hmcshutdown -r -t now

• After about 30 min, the HMC is back again, and you can apply the latest patches (from cental fixes), directly from Web interface.
