Replacement of LAN Cards
Chapter 3100
Replacement of LAN Cards
If you have a LAN card failure, which requires the LAN card to be
replaced, you can replace it on-line or off-line depending on the type of
hardware and operating system you are running. It is not necessary to
bring the cluster down to do this.
Off-Line Replacement
The following steps show how to replace a LAN card off-line. These steps
apply to both HP-UX 11.0 and 11i:
1. Halt the node by using the cmhaltnode command.
2. Shut down the system using /etc/shutdown, then power down the
system.
3. Remove the defective LAN card.
4. Install the new LAN card. The new card must be exactly the same
card type, and it must be installed in the same slot as the card you
removed.
5. Power up the system.
6. If necessary, add the node back into the cluster by using the
cmrunnode command. (You can omit this step if the node is
configured to join the cluster automatically.)
On-Line Replacement
If your system hardware supports hotswap I/O cards, and if the system is
running HP-UX 11i (B.11.11 or later), you have the option of replacing
the defective LAN card on-line. This will significantly improve the
overall availability of the system. To do this, follow the steps provided in
the section “How to On-line Replace (OLR) a PCI Card Using SAM” in
the document Configuring HP-UX for Peripherals. The OLR procedure
also requires that the new card must be exactly the same card type as
the card you removed to avoid improper operation of the network driver.
Serviceguard will automatically recover the LAN card once it has been
replaced and reconnected to the network.
