Chapter 7. Virtualization 307
Note the values that were made by the wizard:
– The desired virtual processor count is 10 (as specified when creating the
virtual server). This count translates to a desired processing unit setting
of 1.0.
– The maximum virtual processor count is 20. The maximum count is always
the desired count plus 10. The maximum processing units setting is also
set to 20.
– The minimum virtual processors setting is set to 1, with the processing
units set to 1.
– The sharing mode is set to uncapped with a weight of 128. Verify that this
setting is what is acceptable for the virtual server.
4. Similar observations and modifications can be made regarding the memory
settings by using the Memory tab in the profile window. The default minimum
memory is 256 MB. Increase this memory for an AIX virtual server.
7.3.2 Using the CLI
To change the values for the VIOS using the CLI, run the following command:
smcli chsyscfg -r prof -m p4601 -i
“name=OriginalProfile,lpar_name=vios1,min_proc_units=1.0,max_proc_units
=2.0,desired_procs=4,max_procs=16,uncap_weight=200,min_mem=512”
Success is indicated when the prompt returns and no error message
is displayed.
Run smcli lssyscfg to confirm that the changes occurred.
Maximum virtual processors: Based on the observed default values from
the virtual server creation wizard, the maximum virtual processors probably
need to be reduced in line with the number of processors in the pool if
uncapped, or the processing unit value (rounded up) if capped. In addition,
the minimum values are probably too small and need to be raised to a
more realistic value for the use of the virtual server.
