DIMMDEALLOC cell dimm OFF deconfigures the specified DIMM
( dimm ) on the cell ( cell ) indicated.
DIMMDEALLOC cell dimm ON configures the specified DIMM on the
cell.
For example, DIMMDEALLOC 0 1B OFF sets DIMM 1B on cell 0 to be
deallocated the next time the partition boots, and as a result all other
DIMMs in the same rank (1A, 1C, and 1D) also will not be used.
Enter HELP DIMMDEALLOC for details.
Step 4. Reboot the partition using the REBOOT command.
Whenever changing cell, processor, or memory configurations you must
reboot the corresponding partition to allow the configuration changes to
take place.
HP-UX This procedure (parmodify -p # -m # ::[y|n]:) configures or
deconfigures (makes inactive) cells from the HP-UX command line.
Step 1. Log in to HP-UX on the partition whose cell you want to configure or
deconfigure.
Step 2. Issue the parstatus -C command to list all cells, their partition
assignments, their actual (current) usage, and their use-on-next-boot
values.
Step 3. Issue the parmodify -p # -m # ::[y|n]: command to configure or
deconfigure the specified cell (-m # ) from the partition (-p # ).
The parmodify -p # -m # ::n: command deconfigures the specified cell
(-m # ). This sets the cell’s use-on-next-boot value to “n” (do not use).
The parmodify -p # -m # ::y: command configures the specified cell to
be used. This sets the cell’s use-on-next-boot value to “y” (use the cell).
The partition number (-p # ) you specify must be the local partition
number, which you can list using the parstatus -w command.
Step 4. Reboot the partition using the shutdown -R command.
You must reboot the partition to allow the new use-on-next-boot values to
take effect.
