Manual Recovery from a PCI Error
After a successful automatic PCI error recovery, if another PCI Error is detected within the time interval
specified by the pci_error_tolerance_time tunable, the card in the I/O slot will be suspended. A manual
PCI Error Recovery operation is required to restore the card.
The following error messages are examples of what will be displayed on the console, if a PCI error is detected
within the time interval specified by the pci_error_tolerance_time tunable following an automatic PCI
error recovery:
PCI Error reported at Hardware Path 7/0/12
Multiple PCI Errors reported at Hardware path 7/0/12 within
pci error tolerance time limit of 1 minutes.
Refer to pci_error_tolerance_time(5) man page for details.
Automatic PCI Error Recovery Operation failed at Hardware path 7/0/12.
Path may be recovered using a Manual Error Recovery operation.
Refer to olrad(1M) man page for details.
A successful attempt at manual recovery will restore the card. A failed attempt at manual recovery will
confirm that there is a persistent error condition.
To recover from the PCI error manually, follow these steps:
1. Execute the olrad -q command to confirm that the card is suspended. In the following example, the
device in slot 8-0-1-7, path 7/0/12/1, is suspended:
