interfaces – lan15 and lan16. The standby heartbeat interface is link aggregate lan905,
which is made up of 2 interfaces - lan18 and lan19.
3. Determine the hardware paths of the interfaces.
a) Determine the names of the interfaces.
b) Enter the following ioscan command to determine the hardware path numbers:
/usr/sbin/ioscan -kfC lan
The output should look something like this:
Class I H/W Path Driver S/W State H/W Type Description
=======================================================================
lan 0 8/16/6 btlan CLAIMED INTERFACE Built-in LAN
.
lan 9 1/12/2 btlan CLAIMED INTERFACE HP PCI 10/100Base-TX 4 port
.
lan 10 1/13/4 btlan CLAIMED INTERFACE HP PCI 10/100Base-TX 4 port
.
lan 15 1/14/1 btlan CLAIMED INTERFACE HP PCI 10/100Base-TX 4 port
.
lan 16 1/15/1 btlan CLAIMED INTERFACE HP PCI 10/100Base-TX 4 port
.
lan 18 1/17/1 btlan CLAIMED INTERFACE HP PCI 10/100Base-TX 4 port
.
lan 19 1/18/1 btlan CLAIMED INTERFACE HP PCI 10/100Base-TX 4 port
c) This output shows the LAN interfaces on your system. The “I” column indicates the
instance number. For example, instance number 9 corresponds to the lan9 network
interface, and the hardware path is 1/12/2 for this interface.
d) Likewise, the above output shows that the hardware path for the lan10 network
interface is 1/13/4.
e) For the standby link aggregate consisting of lan18 and lan19, lan18 (with an
instance of 18) has a hardware path of 1/17/1. For lan19, a hardware path of
1/18/1.
4. Identify the processors.
a) Note the hardware path obtained in the ioscan procedure in the previous step.
b) Enter the following interrupt migration command: /usr/contrib/bin/intctl
The output should look something like this:
