PCI / PCIe Error Recovery Product Note, September 2010

Confirm PCI Error Recovery is Supported
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 on legacy platforms 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-express ER functionality can be enabled on HP Superdome 2 platform only if patches
PHKL_41301 and PHKL_41302 are installed on HP-UX 11i v3 OS.
This feature can be 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.
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
NOTE: The sysrev command is supported only on legacy platform. Use the machinfo
command on HP Superdome 2 to confirm the system firmware version.
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
