Managing PCI Cards with OLAR

Performing OLAR procedures from the command line

1. Replace the PCI cover plate

2. Connect the appropriate I/O cable to the installed PCI card

3. Insert the SPU back into the cabinet

4. For PCI I/O cards on the left-hand side of the SPU, you may need

to re-install the rear door

Step 9. Turn on power to the target slot(s):

# rad -i slot_ID

If the target slot is successfully powered on, the command prompt is

returned and the slot’s green power LED turns on.

Step 10. Resume drivers for any affected cards:

# rad -r slot_ID

rad returns the command prompt upon successful resumption of the

driver. If for some reason the driver instance cannot be resumed (new

card is not compatible with existing driver or requires too much power),

rad outputs an error message to console.

Step 11. Conﬁgure the new card:

a. Run rad (-q and then -c options) to obtain / verify the hardware path

of the new card.

b. Use this hardware path with ioscan to complete conﬁguration of new

card, for example:

ioscan -H hw_path

Note that by using the -H option, you are limiting the scope of the ioscan

to the hardware path you specify and any I/O nodes below it. This helps

to speed the operation, and limits the introduction of other problems

within the system

Step 12. Check for the existence of an OLAR post_add script in

/usr/sbin/olard.d/. Refer to the section “OLAR Scripts” for script naming

conventions and general script information. If the driver requires no

post-replacement action, then no script will be present.

If the script is present, perform the following steps:

a. Execute the script for the target slot:
