##################################################################### INSTALLATION #####################################################################

(A) First-time Installation of IT Assistant 8.8

See the "Dell OpenManage Installation and Security User's Guide" and "Dell OpenManage IT Assistant Version 8.8 User's Guide" for instructions on setting up IT Assistant for the first time on a system.

(B) Upgrade from IT Assistant 6.x to IT Assistant 8.8

IT Assistant 8.8 does not support a direct upgrade from versions 6.x or older. To upgrade from version 6.x to 8.8, first install version

7.0, and then apply version 8.8 as an upgrade.

NOTE: During an upgrade from version 6.x of IT Assistant to version

7.0, the installation will preserve the following settings:

(a) Global configuration settings (b) Discovery configuration settings (c) Event Stored actions

Any other database information such as custom groups, custom event filters, or event categories are not migrated because the database schema is not compatible with earlier versions of IT Assistant. To save this information, back up your original database before upgrading.

If you have changed the data that was pre-populated as part of the 7.0 install in the Report and EventSource tables, but want to retain this data after upgrading to version 8.8, take a back up of these tables and restore them manually after the upgrade.

NOTE: If you used the CIM protocol before an upgrade, then after an upgrade, it is important to verify the CIM credentials. CIM credentials should be qualified with a domain or localhost if no trusted domain is configured (for example, domain\administrator or localhost\administrator). You can view the CIM credentials by editing the imported discovery ranges in the "CIM Configuration Pane." If the CIM credentials are not qualified with a domain or localhost, devices will not be discovered through the CIM protocol.

##################################################################### USER NOTES #####################################################################

* The processor count in IT Assistant will differ for managed systems that contain processors with multiple cores or HyperThreading enabled. The count differs based on whether the managed system

is discovered using the CIM or SNMP protocol. The systems

discovered using SNMP will report physical processors, and the systems discovered using CIM will report logical processors.

* IT Assistant can receive and process alerts from systems with IPv4 address format.

--------------------------------------------------------------------Software Updates

--------------------------------------------------------------------NOTE: IT Assistant does not support the software update task on the management station. This is because a software update may require a reboot that may affect other scheduled tasks that are run on the management station. You can perform software updates using the "Dell Systems Management Tools and Documentation" DVD after closing the IT Assistant application.

--------------------------------------------------------------------Software Updates for Linux

--------------------------------------------------------------------To perform a remote Linux software update, IT Assistant uses Plink for SSH communication. By default, IT Assistant passes your password as a command-line parameter to Plink.

NOTE: This occurs only on the IT Assistant management station. Passwords are always encrypted when transferred to the managed system.

If passing passwords through the command line on the IT Assistant management station is of concern, you can configure the updates to use RSA keys instead of passwords. A blank password in IT Assistant will trigger SSH authentication using the RSA keys.

To create RSA keys, perform the following steps:

NOTE: It is assumed that you are running an SSH2 server and are using the RSA2 keys.

1. Run PuTTYgen (or your preferred mechanism) for generating public/ private key pairs. You can save your private keys (".ppk" files) to any location on your system.

The following is a sample public key that you would put in a file that you create called "authorized_keys2 for RSA2 keys."

ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAIEAxfMzTwS4Cwnua61h7kiad9l3Hvl SeFIYPsZOrCYMuA++

9mPRraUEtrKNkwdaPKqPnc2/JFHyAxOu31jfUgQqgM2CSqwdr7fuowjseVVPTuG 5JdVR1BwUAXlJK/ Hy1BM+mkKHMuNe0jTrN/gUxcmlA0lHFaFNRjV++AeM15upJsk= rsa-key-20050209

Linux ships with other utilities for creating public/private key pairs. You can download PuTTYgen from the following Web address: "http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html"

The public keys are saved in the following configuration file on

the Linux system. ~/.ssh/authorized_keys2

2. Create this file, if it is not present.

3. You can store the private keys in the directory of your choice. For security reasons, it is recommended that you set the appropriate permissions for your private key files.

This is a sample "sshconfig.pro" file where you can configure the names and location of your private keys:

#server[.user]=<path-to-file> #A server-name of global would be appropriate to accommodate a network where all or most systems are set up using the same key. #global[.user]=<path-to-file> global.root=C:\SSH Private Keys\root\global_root_privatekey.ppk global.fred=C:\SSH Private Keys\fred\global_fred_privatekey.ppk

192.168.157.149.root=C:\SSH Private Keys\root\ system1_root_privatekey.ppk

192.168.157.151.fred=C:\SSH Private Keys\fred\ system2_fred_privatekey.ppk

4. Copy "sshconfig.pro" to the bin folder of IT Assistant. By default, this folder is located at: "C:\Program Files\Dell\SysMgt\ITAssistant\bin directory

NOTE: A blank password in IT Assistant triggers SSH authentication using the RSA keys instead of using passwords. IT Assistant then attempts to find the entry in the "sshconfig.pro" file. If IT Assistant finds the system and user or global key in "sshconfig.pro", it uses the ".ppk" file for establishing an SSH connection to the server. However, if IT Assistant cannot find this information, it assumes that you meant to enter a blank password.

Dell recommends that SSH version 2 or above be used on the managed system for better security.

For more information on the usage of public keys for SSH authentication, see "http://www.tartarus.org/~simon/puttydoc/Chapter8.html"

--------------------------------------------------------------------Reports

---------------------------------------------------------------------

1) When you install IT Assistant, an in-built utility generates a report on the applicable software updates on the systems that IT Assistant discovered. This report is generated by comparing the versions of the packages/bundles imported into the IT Assistant repository (in the Software Updates) and the versions installed on the managed systems. The utility is present under the folder "<ITA Installation Directory\bin>" and is named
