PCI Error Recovery Product Note What is PCI Error Recovery? The PCI Error Recovery feature provides the ability to detect, isolate, and automatically recover from a PCI error, avoiding a system crash. PCI Error Recovery is included with the HP-UX 11i v3 operating system, and it is enabled by default. NOTE PCI Error Recovery is not supported on all platforms. To determine if PCI Error Recovery is supported on your system, see the PCI Error Recovery Support Matrix, available at http://docs.hp.com/en/ha.
PCI Error Recovery Product Note Confirm PCI Error Recovery is Supported Confirm PCI Error Recovery is Supported Step 1. To confirm PCI Error Recovery (ER) is supported with your configuration and system firmware version, see PCI Error Recovery Support Matrix, HP-UX 11i v3 at: http://docs.hp.com/en/ha.html NOTE PCI-express ER functionality can be enabled only if the patch set: PHKL_37099, PHKL_37329, PHKL_37330, PHKL_37331, PHKL_37648, PHKL_37405, and PHKL_37510 is installed on HP-UX 11i v3 OS.

PCI Error Recovery Product Note Confirm PCI Error Recovery is Supported NOTE The sysrev command output on some systems includes extra zeros in the system firmware version number. These zeros can be ignored. For example, 3.88 and 3.088 on Integrity systems are the same firmware version, also 23.1 and 23.001 on HP 9000 systems represent the same firmware version. Step 3. The system firmware is the main component of the firmware recipe required to support PCI Error Recovery.

PCI Error Recovery Product Note Error Messages for PCI Error Recovery Error Messages for PCI Error Recovery All drivers that support PCI Error Recovery generate error messages for specific PCI Error Recovery events. Mass storage drivers post error messages to syslog and to diaglog. If a mass storage driver generates verbose error messages, they can be accessed in the Support Tools Manager (STM) diagnostic logs. Networking drivers post error messages to the console and to syslog.

PCI Error Recovery Product Note Manual Recovery from a PCI Error For more information on manual recovery from a PCI error, see “Manual Recovery from a PCI Error” on page 13. 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.

PCI Error Recovery Product Note Manual Recovery from a PCI Error • You can perform an OL* online replacement operation to replace the I/O card with an I/O card that has the same HP Manufacturing Part Number and the same (or later) release version number. • You can perform an OL* online deletion operation to delete the card and the driver instance associated with that card. After a successful online deletion, the slot is available to be used with another I/O card.
