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.

This feature can be turned turned off by setting the static kernel tunable

pci_eh_enable to zero. By setting this tunable to zero, the ER feature will be disabled

for both PCI-X and PCI-express I/O slots. The value of the tunable is persistent

across reboots.

Step 2. To confirm the system firmware version installed on your system, or any cell in your system, use

the sysrev command from the management processor Command Menu (CM) prompt:

MP:CM> sysrev

The sysrev command output on Superdome systems is different from the sysrev command output

on the other systems that support PCI Error Recovery.

The sysrev command output on Superdome systems will list the system firmware version under

the SYS FW heading as illustrated in the following example:

MP:CM> sysrev
