Setting and Checking nPartition

Core Cell Choices

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.

You can list and set an nPartition’s core cell choices by using these

procedures:

• Setting nPartition Core Cell Choices [BCH] on page 297

This procedure (Conﬁguration menu, COC command) sets the core

cell choices for an nPartition using the nPartition’s BCH interface.

• Setting nPartition Core Cell Choices [HP-UX] on page 297

This procedure (parstatus and parmodify commands) lists and sets

the core cell choices for an nPartition using HP-UX commands.

• Setting nPartition Core Cell Choices [Partition Manager] on page 299

This procedure (Partition —> Modify Partition action, Cell Cell

Choices tab) sets the core cell choices for an nPartition using Partition

Manager.

NOTE You do not need to specify core cell choices for a valid core cell to be

chosen.

By default on HP Superdome and HP rp8400 server, system ﬁrmware

selects the lowest numbered eligible cell as an nPartition’s active core

cell. By default on HP rp7410 servers, cell 1 is selected as the core cell.

NOTE You should specify only core-capable cells as core cell choices. A cell must

have an I/O chassis with core I/O attached to be eligible to be chosen as

the core cell.
