HP Serviceguard Version A.11.18 Release Notes, September 2008

IMPORTANT: If your storage devices are configured with only a single path, or you
have disabled multipathing, you should disable PCI Error Recovery; otherwise
Serviceguard may not detect when connectivity is lost and cause a failover.
For instructions on using the pci_eh_enable parameter to disable PCI Error Recovery,
see the “Tunable Kernel Parameters” section of the latest edition of the PCI Error Recovery
Product Note in the High Availability collection on docs.hp.com.
Online Replacement of LAN Cards Requires Patch
Before you can replace a LAN card online (without bringing down the cluster) as
described under “Replacing LAN or Fibre Channel Cards” in Chapter 8 of Managing
Serviceguard, you must apply patch PHNE_35894. See “Patches for this Version”
(page 77) and “JAGag27186 (SR8606472298): OLR of a LAN Card in SG cluster fails on
