nPartition Administrator's Guide, Second Edition

From Partition Manager Version 2.0, use the Set Cell Options tab to configure cell
use-on-next-boot values, and use the Configure Memory tab to configure cell local memory
values.
CAUTION: Memory configured as cell local memory only can be used by operating systems
that support it.
Any memory configured as cell local memory is unusable when an nPartition runs an
operating system that does not support it.
5. After changing attribute values for all the cells you plan to modify, click the OK button.
6. Review all information presented in the Notes and Warnings, the Summary of Changes,
and the HA Checks tabs.
7. Either cancel or proceed with the cell attribute changes.
Click the Cancel button to cancel the changes.
To proceed with the cell attribute changes, click the Finish button or click the OK button.
8. Reboot the nPartition to use the cells' new attribute values.
On cell-based servers based on the HP sx1000 chipset or HP sx2000 chipset, if you have
changed cell local memory (CLM) values then you must reboot the nPartition whose CLM
values have changed. If you also are changing use-on-next-boot values then also use the
following guidelines.
If you have changed any cell use-on-next-boot settings for the nPartition then reboot the
nPartition in either of two ways:
• Perform a standard reboot (HP-UX: shutdown -r; Windows: shutdown /r; Linux:
shutdown -r time; OpenVMS: @SYS$SYSTEM:SHUTDOWN with an automatic system
reboot).
If you have only changed use-on-next-boot values from y to n, then perform a reboot.
Any cells set to not be used will still be assigned to the nPartition but will not be used
(will not rendezvous) in the nPartition.
• Perform a reboot for reconfig (HP-UX: shutdown -R; Windows: shutdown /r; Linux:
shutdown -r time; OpenVMS: @SYS$SYSTEM:SHUTDOWN with an automatic system
reboot).
If you have changed any use-on-next-boot values from n (do not use on next boot) to
y (use the cell on next boot), then you must perform a reboot for reconfig to allow the
currently inactive cells to reboot and rendezvous when the nPartition reboots.
Setting nPartition Core Cell Choices
You can set the core cell choices for an nPartition by using any one of the following procedures:
• “Setting Core Cell Choices (BCH Menu)” (page 195)
• “Setting Core Cell Choices (EFI Shell)” (page 195)
• “Setting Core Cell Choices (nPartition Commands)” (page 196)
• “Setting Core Cell Choices (Partition Manager)” (page 197)
The core cell choice settings for an nPartition are optional preferences that establish which cells
in the nPartition are preferred to be selected as the core cell for the nPartition.
