We will show the installation of iFixes using an example. The example HMC has version V10R3M1050, so far without iFixes:

$ hmc version -i hmc01
hmc01   V10R3 SP1050
$ 

Available iFixes can be viewed with “hmc flrt”:

$ hmc flrt -l hmc01
HMC and vHMC

No available iFixes are displayed for the currently installed version. However, a new iFix (MF71421 for x86 and MF71422 for ppc) with Java security fixes for version V10R3M1050 was released a few days ago. However, IBM has not yet added this information to FLRT. However, the iFix can already be found on IBM Fix Central.

The following shows the installation using the example of MF71422 and a Power based HMC. If you replace MF71422 with MF72421, you have the procedure for an x86 based vHMC.

The iFix should be downloaded and placed on a local server, see Download Fixes, Service Packs and Release Levels:

$ ssh 172.16.199.10 ls -l /export/hmc/MF71422_ppc.iso
-rw-r--r--    1 root  system 2796261376 Dec 16 09:13 /export/hmc/MF71422_ppc.iso
$

The iFix can then be installed on the HMC using the command “hmc updhmc”:

$ hmc updhmc -r hmc01 sftp://fwtrans:PASSWORD@172.16.199.10//export/hmc/MF71422_ppc.iso
INFO: using sftp://fwtrans:PASSWORD@172.16.199.10//export/hmc/MF71422_ppc.iso

The system is shutting down for reboot now.

After the reboot, the HMC displays the iFix that was just installed:

$ hmc version -i hmc01
hmc01   V10R3 SP1050
   MF71422 - iFix for HMC V10R3 M1050
