To change the plug count for a particular module, enter a menu index number. For example, to change
the plug count of the L3 module that is physically in the upper-right corner (U1.18-P1-C8), type 5, then
enter the new plug count.
When all of the new plug counts have been entered, select 50, Commit the values and write to the
VPD. This action stores the new values in NVRAM.
Determining the number of MCMs in a system: To determine the number of MCMs installed in the
system, do one of the following:
– If the managed system is powered down, go to "System Information Menu" on page 795, then to the
section titled "Processor Configuration/Deconfiguration Menu" and refer to the example menu. The
VPD port is shown as x.y, where x is in the range 3-6 and y is in the range 0-7.
The listing of the VPD ports on the screen is used to determine the number of MCMs in the
managed system.
3.y=MCM0 (U1.18-P1-C1)
4.y=MCM1 (U1.18-P1-C4)
5.y=MCM2 (U1.18-P1-C3)
6.y=MCM3 (U1.18-P1-C2)
– If AIX is booted on the managed system, issue the following command on the AIX command line, to
display a line of information for each MCM installed in the system:
lscfg -vp | grep MCM
The following table shows the plugging order of each MCM and its associated L3 cache modules.
