Moving from ICLE to ICE-Linux

• Serial console access and logging. The HP Proprietary Console Management Facility (CMF)

captures serial console messages into per-system log files, which reside on the CMS, and enables

direct access to a managed system's console through an interactive terminal session.

• Remote power control. This enables you to reboot, power on, and power off a managed

system through its management processor.

• Boot to a Linux rescue mode. This enables you to boot a managed system to a rescue Linux-

based environment containing basic management and configuration tools.

Migration Ideas and Tools

While there is no direct upgrade path available between ICLE and ICE-Linux, there are a number of

pieces that can be transitioned between them, depending on your requirements.

Preserving IP Addresses

Using ICLE, after a managed server is registered, its IP address is registered such that it will not

change on subsequent DHCP requests. If you use these addresses in a routed environment, it may be

useful to be able to extract those addresses, and convert them into the format required by the ICE-

Linux DHCP server. The following script extracts the IP addresses from ICLE and writes them to

standard output that can be pasted into an appropriate subnet section of an ISC DHCPd configuration

file so that the new product will provide the same IP addresses used.

#!/bin/bash

# convert_icle_leases.sh

# Obtain the list of discovered servers and attributes from ICLE, and

# generate static IP address registrations for ISC DHCPd. The output

# section can be modified to generate configurations for other DHCP

# daemons as required. This is an example of using database data

# from ICLE to assist in the migration to ICE-Linux.

# This script is provided as-is.

lease_cmd="select mac, ip, hostname from dnsmasq_lease order by ip"

leases=$(psql -A -t -q --field-separator=, -c "$lease_cmd" rlx_ct postgres)

hostname_prefix="cthost"

hostname_index=1;

for i in $leases; do

# Loop through each record obtained from the database, assigning

# values to variables for use below.

mac=$(echo $i|cut -d, -f1)

ip=$(echo $i|cut -d, -f2)

hostname=$(echo $i|cut -d, -f3)

if [ "$hostname" == "*" ]; then

hostname="$hostname_prefix-$hostname_index"

let "hostname_index=$hostname_index + 1";

# Output new DHCP configuration information for hosts found

# in the ICLE database. Modify this section if you wish the

# output to be different for another DHCP server configuration.

echo "host $hostname {"

echo " hardware ethernet $mac;"
