Managing PCI Cards with OLAR

Performing OLAR procedures from the command line

How to On-Line Add (OLA) a PCI Card using rad

Step 1. Before physically inserting a new interface card into the system, consider

the following impacts that doing so will have on a system and review the

applicable topics within the section “Planning and Preparation” for

detailed information:

• The new card must be compatible with the system

• Each OLAR-capable PCI slot provides a set amount of power, so the

new card cannot require more power than is available

• The new card must operate at the slot’s bus frequency

• The correct driver for the card must be conﬁgured in the kernel. The

cards documentation indicates which driver is required. In most

cases, the new card will be the same type as a card already in the

system, so the driver will already be loaded into the kernel.

— If the required driver is not already in the kernel and the driver is

a dynamically loadable kernel module (DLKM), you will need to

load it from the command line.

— If the required driver is static and not conﬁgured in the kernel,

you will need to add the driver to the kernel manually at another

time, which will require a reboot of the machine.

Step 2. From the command line, make sure that the correct driver for the card is

loaded and conﬁgured in the kernel.

Step 3. Obtain the slot ID of an available slot into which you can add a new

interface card. For example:

# rad -q

Slot Path Bus Speed Power Occupied Suspended Driver(s)_Capable

1 0/5 40 33 On Yes No Yes

2 0/4 32 33 Off No N/A N/A

4 0/8 64 33 Off No N/A N/A

5 0/10 80 33 On Yes Yes Yes

6 0/2 16 33 On Yes No No

Select a slot that is available (Occupied ﬁeld = No) and write it down.

Step 4. Verify that the target card slot reported by rad is consistent with the
