Managing nPartitions

Setting and Checking nPartition Core Cell Choices

HP System Partitions Guide: Administration for nPartitions, rev 5.1

299

The order in which you list the cells is the order in which the nPartition’s

core cell choices are established; the ﬁrst cell listed is the ﬁrst preferred

core cell (choice 1), and the subsequent cells are lower-priority core cell

choices (choices 2 through 4, if speciﬁed).

Step 3. [Optional] If you wish to immediately use the new core cell choice

settings, reboot the nPartition whose core cell choices you have changed.

Even if you do not reboot now, the new core cell choices will be used the

next time the nPartition is rebooted.

You can issue the shutdown command with the -r option to reboot the

nPartition and use the new core cell choice settings. (You do not need to

perform a reboot for reconﬁg of the nPartition.)

If you have modiﬁed an inactive remote nPartition, use the service

processor Command menu’s BO command to boot the remote nPartition;

the designated core cell choices will be used to select the active core cell.

Setting nPartition Core Cell Choices [Partition Manager]

This procedure (Partition —> Modify Partition action, Cell Cell Choices tab)

Step 1. Run Partition Manager (/opt/parmgr/bin/parmgr) or access it from

SAM or a Web browser.

Step 2. In the Partition Manager primary window, select the nPartition whose

core cell choices you want to change.

Click the nPartition’s name in the list on the left side of the primary

window to select the nPartition.

Step 3. Select the Partition —> Modify Partition action, and click the Cell Cell

Choices

tab.

Step 4. Modify the core choice setting for each cell whose core choice priority you

want to revise.

Highlight the cell whose core cell choice you want to conﬁgure, select the

desired choice priority (1st, 2nd, none, etc.) from the Core Cell Choice

pop-up list, and click the Modify button to modify the priority.

Step 5. Click the OK button when done changing the core choice priorities (or

click Cancel to not revise any priorities).
