HP-UX 11i v3 Installation and Update Guide, September 2007 (Update 1 Release)

Table A-1 Known Install and Update Problems (continued)
Description/ActionProblem
Online replacement (OLR) of a LAN card in a Serviceguard cluster
fails on a system running HP-UX 11i v3 because the Critical Resource
Analysis (CRA) performed as part of the OLR operation returns
CRA_SYS_CRITICAL. You will encounter this problem on HP-UX
11i v3 whether you use the Peripheral Device Tool (pdweb) or the
HP-UX olrad command.
What To Do
Apply patch PHNE_35894. You can apply the patch without a reboot.
If the patch is not available or for some reason you need to proceed
without the patch, you must remove the node from the running
cluster (cmhaltnode), shut down the node, and then replace the
card, as described under Replacing LAN or Fibre Channel Cards in
chapter 8 of the Managing Serviceguard manual.
See Replacing LAN or Fibre Channel Cards in chapter 8 of Managing
Serviceguard for more information.
Uninstalling HP-UX 11i v3
If you cannot resolve problems after installing HP-UX 11i v3, then you may want to
un-install it. The process depends upon the install process you followed:
• If you previously created an operating system recovery image with either
make_net_recovery or make_tape_recovery using Ignite-UX, boot the
system from that media to return the OS and any archived applications to the
previous release. Refer to the Ignite-UX Administration Guide available on the Instant
Information DVD and on the HP Technical Documentation Web site:
http://docs.hp.com
• If you do not use Ignite-UX or do not have a current operating system recovery
image:
— If your applications and data are on a separate disk from the OS, cold-install
the previous OS. Doing this ensures a clean OS installation, removing all
previous upgrade and patch information.
— If applications, data, or both are on the same volume with the OS, boot from
the previously-saved system recovery tape to return to a previous OS. These
expert recovery processes are in the Ignite-UX Administration Guide.
To determine which applications are on the system and where they are located, use
swlist. If you only need to remove applications or patches from the system, use
swremove. Refer to the Software Distributor Administration Guide for details.
