Support of PCI/PCI-Express Error Handling and Error

Recovery on HP-UX

PCI error handling and error recovery are supported only with some HP-UX version, I/O products and servers. For more information, see the support matrix available at the following location:

http://www.hp.com/go/hpux-networking-docs under HP-UX 11i v3 I/O Cards category.

There are several kernel tunables that can change the behavior of PCI error recovery operation. For more information about the kernel tunables, see Tunable Kernel Parameters section in the PCI Error Recovery Product Note, 4th Edition, March 2010 document, posted at the following location:

http://www.hp.com/go/hpux-networking-docs under HP-UX 11i v3 I/O Cards category.

The above link provides information about PCI Error Recovery functionality, which is supported on HP- UX 11i v3 system.

For more information about the type of errors and corresponding events supported by the product on all platforms, see PCI / PCIe Error Recovery Product Note available at http://www.hp.com/go/hpux-networking-docs under HP-UX 11i v3 I/O Cards category.

Summary

The basic RAS features designed for HP Integrity and HP 9000 servers, when coupled with the PCI error handling and recovery mechanisms, enables high-end servers to meet the needs of a mission-critical environment. This is made possible by preventing customers from experiencing down-time as a result of system hang or unusable state of a system.
