Virtual I/O server installation images on an HMC can be changed using the “hmc chviosimg” command. Currently, only the name of an image can be changed by setting the new_name attribute.

We show this with the following example:

LPAR-Tool
$ hmc lsviosimg hmc01
NAME                                    SIZE     IMAGE_FILES
Virtual_IO_Server_Base_Install_4.1.0.0  3487.68  dvdimage.v1.iso
VIOS_3.1.4.30                           6063.53  dvdimage.v1.iso,dvdimage.v2.iso
$ 
HMC-CLI
hscroot@hmc01:~> lsviosimg
name=Virtual_IO_Server_Base_Install_4.1.0.0,image_files=dvdimage.v1.iso,size=3487.68
name=VIOS_3.1.4.30,"image_files=dvdimage.v1.iso,dvdimage.v2.iso",size=6063.53
hscroot@hmc01:~> 

The name Virtual_IO_Server_Base_Install_4.1.0.0 is very long and should be changed to the shorter name VIOS_4.1.0.0:

LPAR-Tool
$ hmc chviosimg hmc01 Virtual_IO_Server_Base_Install_4.1.0.0 new_name=VIOS_4.1.0.0
$ 
HMC-CLI
hscroot@hmc01:~> chviosimg -n Virtual_IO_Server_Base_Install_4.1.0.0 -o s -a new_name=VIOS_4.1.0.0
hscroot@hmc01:~>
