Introduction

This document describes the network card requirements of Cisco Basic Paging Server for an upgrade from version 11.5.1 to version 12.0.1.

Contributed by John Barreto, Cisco TAC Engineer.

Problem

Upgrade of Cisco Basic Paging Server from version 11.5.1 to version 12.0.1 fails with error "A subcommand of the upgrade failed unexpectedly during pre-flight. Your system is unchanged."

Troubleshooting

The upgrade fails with the error message as shown in the image here:

Use the following steps to identify the issue:

Step 1. Collect the upgrade-preflight-checks logs after the upgrade failure

Note: The information in this link explains how to collect the Informacast logs: http://www.singlewire.com/thank-you-logtool-t.html

Step 2. Review the upgrade-preflight-checks.log for the error

From the logs we can see the following error:

+(/etc/rc5.d/S98startupgrade:162): main(): . /usr/local/singlewire/platform/bin/bring-up-network.sh

++(/usr/local/singlewire/platform/bin/bring-up-network.sh:4): source(): /bin/cp /tmp/deb/etc/network/interfaces /etc/network/interfaces

++(/usr/local/singlewire/platform/bin/bring-up-network.sh:6): source(): /sbin/ifdown eth0

ifdown: interface eth0 not configured

++(/usr/local/singlewire/platform/bin/bring-up-network.sh:7): source(): /sbin/ifup eth0

eth0: ERROR while getting interface flags: No such device

SIOCSIFADDR: No such device

eth0: ERROR while getting interface flags: No such device

SIOCSIFNETMASK: No such device

SIOCADDRT: No such device

Step 3. Confirm the current network card enabled on the Cisco Basic Paging 11.5.1 server is VMXNET3

As Cisco Basic Paging server 12.0.1 does not support VMXNET3 network card, the upgrade fails at the upgrade-pre-flight check stage.

Solution

Power down the Cisco Basic Paging 11.5.1 server and change the network adapter type to E1000 and re-run the upgrade.
