Step 2. To change cell or processor configurations access the Configuration
menu, or to change memory configurations access the Service menu.
To access the Configuration menu enter CO at the BCH interface’s main
menu. To access the Service menu enter SER.
Step 3. Configure or deconfigure the cell, processors, or memory.
You cannot deconfigure the last cell, processor, or DIMM rank. Cells
must have at least one configured processor or DIMM rank, and
partitions must have at least one configured cell.
• Cells
From the Configuration menu use the CELLCONFIG command to
configure or deconfigure a cell in the partition.
CELLCONFIG # OFF deconfigures the cell ( # ) by setting its
use-on-next-boot value to “n” (do not use).
CELLCONFIG # ON configures the specified cell ( # ) by setting its
use-on-next-boot value to “y” (use the cell).
Enter HELP CELLCONFIG for details.
• Processors
From the Configuration menu use the CPUCONFIG command to
configure or deconfigure a processor on a cell in the partition.
CPUCONFIG cell cpu OFF deconfigures the specified processor ( cpu )
on the specified cell ( cell ).
CPUCONFIG cell cpu ON configures the specified processor on the cell
Enter HELP CPUCONFIG for details.
• Memory
From the Service menu use the DIMMDEALLOC command to configure
or deconfigure memory on a cell in the partition.
DIMMs operate in ranks of four. Each rank is numbered (0, 1, 2, and
so on) and the DIMMs in the rank are lettered (A to D). For example,
rank 0 includes DIMMs 0A, 0B, 0C, and 0D.
When you deallocate a DIMM, all other DIMMs in the rank also will
not be used the next time the partition boots.
