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 0/0/0
Multiple PCI Errors reported at Hardware path 0/0/0 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 49/0/1/2/0.
Path may be recovered using a Manual Error Recovery operation on supported platforms.
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 0-0-1-0, path 0/0/0/1, is suspended:# olrad -q
NOTE:
The olrad capability is supported only on legacy system and is not supported
during the first release of HP Superdome 2 platform.
2.
Execute the ioscan -fnH command on the driver associated with the card in the suspended
slot to confirm the card is in the error state, for example: ioscan -fnH 0/0/0
3.
Execute the olrad -r command to power off the slot, for example:
# olrad -r 0-0-1-0
Activity : Start of Prepare Replace
Target slot : 0-0-1-0
Critical Resource Analysis(CRA) in progress...
[ NOTE: The CRA may take a few minutes to complete on large
configurations. It is recommended not to disrupt this operation. ]
CRA REPORT SUMMARY: CRA returned WARNING.
Detailed CRA report is available in /var/adm/cra.log file.

4.
Execute the olrad -q command to confirm the power is off. In the following example,
power for the device in slot 0-0-1-0, path 0/0/0/1, is off: #olrad -q
5.
Execute the olrad -R command to resume the card, for example:
#olrad -R 0-0-1-0
Activity : Start of Post Replace
Target slot : 0-0-1-0
Hardware path 0/0/0 Successfully recovered from PCI Error
Activity : End of Post Replace
Target slot : 0-0-1-0
