NOTE If the devices on a bus that supports PCI error recovery encounter further errors within the

time interval specified by the pci_error_tolerance_time tunable following automatic error

recovery, they will remain quiesced. If this happens and the devices are in hotpluggable slots,

you can recover manually by using the olrad command or the attention button to do an online

replacement. You can also recover manually using the olrad command to do an online deletion.

For more information on the pci_error_tolerance_time tunable, see “Tunable Kernel

Parameters” on page 10.
