Managing PCI Cards with OLAR

Performing OLAR procedures from the command line

This command will report all I/O nodes on the target card.

Step 6. Check for an OLAR prep_replace script in /usr/sbin/olrad.d/

If the driver requires no preparatory action, then no script will be

present. Refer to the section “OLARD Scripts” for detailed information

regarding the name, location and purpose of the use of OLARD scripts.

If the script is present, perform the following steps:

a. For each port on the target card, execute the script:

# /usr/sbin/olrad.d/drivername prep_replace <hw_path>

b. The prep_replace script does any preparatory work required before

you can suspend driver operation. For example, a networking card

might have to be unbound from a networking operation. Make sure

that running the script produces no error messages before you

proceed with the next step.

Step 7. Suspend the drivers for the target card(s):

# rad -s slot_ID

This displays the hardware path and card identiﬁer, and asks you to

conﬁrm suspension.

Enter Y to continue. For example:

The following interface driver I/O node(s) will be suspended:

0/12/0/0 c720

Do you wish to continue(Y/N)? Y

If the target card is a multi-port card, all I/O nodes will be suspended.

rad returns the command prompt upon successful suspension of the

driver. If for some reason the driver instance cannot be suspended, rad

outputs an error message to console.

Step 8. Turn off power to the target slot(s):

# rad -o slot_ID

If the slot is successfully powered-down, the command prompt is

returned. At this point, the target slot’s green power LED turns off and
