Determining PCI Card Slot Locations

This section describes how to determine which PCI card slot is used by a

ﬁlesystem, network interface, or hardware path (such as a boot device

path).

You may want to identify which PCI cards are used by critical and

non-critical system resources when planning for card replacement or

nPartition reconﬁguration.

NOTE While you can use the manual techniques described here to help identify

which PCI cards support critical system resources, you should rely on the

critical resource analysis that SAM and Partition Manager perform for a

complete analysis of the services a card provides.

You can perform SAM or Partition Manager critical resource analysis for

any card in an nPartition’s active I/O chassis.

When performing a card replacement action, both SAM and Partition

Manager automatically check for any critical system resources that

would be affected by taking the card ofﬂine.

The manual procedures described here use the rad -N

path

command to

identify which PCI card slot corresponds to the speciﬁed hardware path.

The following procedures are provided here:

• Determining a Network Interface’s PCI Card Slot on page 381

• Determining a Filesystem’s PCI Card Slot on page 381

• Determining a Boot Device Path’s PCI Card Slot on page 382

To determine the actual physical location of a PCI card slot, based on the

cabinet-bay-chassis-slot format that the rad command lists, refer to the

chapter nPartition System Overviews on page 31 for an introduction to

nPartition I/O hardware.
