Managing PCI Cards with OLAR
How to On-line Replace (OLR) a PCI Card using SAM
Step 8. Once you click the “OK” button on the Analyze Critical Resources screen,
SAM begins to take the selected card out of service. First, it runs a
“prep_replace” script, if one exist, for each port on the target card.
“prep_replace” executes any preparatory actions required before the
driver is suspended.
Step 9. Once the script has successfully completed, SAM requests a suspend
operation for all ports on the target card.
Step 10. Once the driver has been suspended, SAM turns off the power to the slot
in which the card is located.
Step 11. SAM then illuminates the amber attention LEDon theslot itselfto make
the suspended card more easily located on the system chassis.
Step 12. SAM displays a dialog giving instructions on replacing the card. Read
the contents of this dialog for any extra information. Also at this point,
SAM turns off the slot’s green power LED.
CAUTION At this point you should replace the card, or press “Cancel” to leave the
system with drivers suspended and slot power off. Do not press “OK”
until the target card has been replaced. If “Cancel” is pressed, power can
be restored and the card resumed later with the “Actions->Bring
