Why solaris doesn't see all the DIMMS installed?

Question

This is a SPARC T4-2 Server. It has installed 128GB memory in 16 DIMMS 8GB each.

The prtdiag -v output shows

As you can see, there is a problem with the CH1 DIMMs in the CMP1, but when you see at the SP, those DIMMs are Ok.

i.e.

  /SYS/MB/CMP1/MR0/BOB0/CH1/D0
    Properties:
        type = DIMM
        ipmi_name = P1/M0/B0/C1/D0
        component_state = Enabled
        fru_name = 8192MB DDR3 SDRAM DIMM
        fru_manufacturer = Samsung
        fru_part_number = 7014640,M393B1K70CH0-YH9
        fru_rev_level = 02
        fru_serial_number = ##################
        fault_state = OK
        clear_fault_action = (none)

All slots tagged as "D0" are populated.

Why the DIMMs are mapped as shown in the prtdiag output?

Why solaris doesn't see all the DIMMS installed?
