Interface Card OL* Support Guide

WARNING! Observe all safety precautions to avoid being injured while accessing systems to
add, replace, or delete cards.
CAUTION: Observe all safety precautions prior to physically accessing the system to prevent
static discharge from damaging the system.
IMPORTANT: Online replacement (OLR) of a LAN card in a Serviceguard cluster fails because
the Critical Resource Analysis (CRA) performed as part of the OLR operation returns
CRA_SYS_CRITICAL. You will encounter this problem whether you use the Peripheral Device
Tool (pdweb) or the HP-UX olrad command.
To fix this problem, apply patch PHNE_35894.
NOTE: You can apply patch PHNE_35894 without a reboot.
On a system to which patch PHNE_35894 has been applied, you will be able to perform online
replacement of hot-swappable cards (without bringing down the cluster). For detailed information,
see “Replacing LAN or Fibre Channel Cards” in chapter 8 of Managing Serviceguard, available at
http://docs.hp.com/en/ha.html#Serviceguard.
NOTE: If for some reason you need to proceed without patch PHNE_35894, you must follow the
“Off-Line Replacement” procedure under “Replacing LAN or Fibre Channel Cards” in chapter
8 of Managing Serviceguard.
For more information about this issue, see SR # 8606472298 (JAGag27186).
