IBM Service Management YouTube channel

This is great - a channel containing lots of fairly technical videos of Tivoli products and integrations:

http://www.youtube.com/user/ismconnect?feature=mhum#p/c/5C4BC71AD2C77801

A great tutorial on ITCAMfT integration with TBSM

TBSM is able to read Discovery Library Adapter (DLA) books from a number of products, including ITM, TADDM, and ITCAM for Transactions (there are others, but I don't know of a comprehensive list). Sometimes the specifics about the integration are dependent upon what other products you have installed, but that is a larger discussion also. This piece from IBM contains extremely useful information on how you can filter the data in the ITCAM for Transactions DLA so that it can be processed more quickly by TBSM and increase the quality of the data in TBSM (by eliminating services that are not important):


The information is great, but you definitely have to do some work before you can just follow along. In the example, they exclude all of the .gif, .css and .jpg components. In many shops, this would work great. However, I've been in some companies that have had problems specifically with .css files being moved/renamed/locked/etc., and those companies would definitely not want to exclude those entities. So before you can just dive in, you need to analyze your business needs and the current state of your components. This could be done in a DEV/QA environment, or possibly in a temporary portion of your TBSM implementation.

BitLocker on Windows 7

What is BitLocker?

Windows Vista and 7 included the BitLocker functionality to allow for encryption of the drive.

Deployment Problem:

According to the Info Center documentation, OSD is BitLocker ready. Well, not really. The idea is that OSD has the capability of creating a partition that will allow BitLocker to be activated. The problem is that when OSD creates the partition it assigns a driver letter to the partition and this is not something that can be there for BitLocker to function.

Solution:

As of Windows 7 (and Vista SP1(?), but who cares), Microsoft included a tools called bdehdcfg.exe that allows for the ability to take any partition, shrink it by a certain amount and prepare it for BitLocker. In order for BitLocker to work, it requires a minimum of 100MB or 300MB if you also want the recovery console (For Vista this is 1.5 GB). In order to do this, just use a software module that is deployed with the image to execute the bdehdcfg command.

One thing to note with this solution, when the image is deployed, you will end up with a larger partition than expected. The reason for this is that when the bdehdcfg command is executed, the partition ends up being created at the end of the drive and when OSD is completed, it takes the cache partition (about 500MB) and adds it to the last partition on the drive. So if you are defining bdehdcfg to create a 300MB partition, you will end up with a 800MB partition (approx). Currently the only way around this is to have the bdehdcfg execute after the OSD deployment is completed.

BitLocker sounds simple enough to implement, but there are some things to think about that will impact the business

  1. The PIN is used to provide an additional level of security to the BitLocker process. This PIN is set to the computer not to the user(s) of the computer, so if there are multiple users of the system, then they all share the same PIN.
  2. The PIN can only be set with someone with Administrative access. (I have not personally confirmed this, but I was informed of this by an engineering group, so if this is incorrect, please let me know and I will remove)
  3. There is no native method to enforce a password expiry of the PIN
  4. BitLocker can be disabled/paused by anyone with administrative access, thus leaving the system unprotected.
  5. Will require processes to be put in place when users forget their PIN (you know it will happen) and provide the recovery password. This is possibly the hardest part depending on the users and the number of users.

On the plus side:

  1. It is free so you are able implement encryption without additional software expense
  2. When protected, the encryption seems to be as good as any
  3. Encrypting a drive is relatively quick compared to other vendors
  4. Recovering a drive is simple as you just need the recovery password from Active Directory
  5. Did I mention it was free?

Hope this helps you out :)

Deploying Windows 7 with TPMfOSD

Recently I have been involved in using TPMfOSD to capture and deploy Windows 7 images. There is quite a bit of information available on the web and on IBM’s Info Center, but at times we found that there are certain areas that are not completed enough.

I have been working through the Devworks site with various people and thought I would also give back some information. Since this was too big for Devworks, I thought a blog would be best.

At a high level, here is what I did:
1. Importing Windows 7 DVD for Unattended Install
2. Preparing the OS Configuration for Unattended Install
3. Deploying the Unattended Install
4. Customizing Master Image
5. Executing sysprep
6. Capture Clone Image
7. Modifying the OS Configuration for Clone Install
8. Deploying the Cloned OS

For my environment, I am using VMware Workstation to create my profile. There are many advantages of using VMware rather than physical hardware such as:

1. The image does not contain any drivers for the physical hardware. Windows 7 can be installed on VMware with almost no extra drivers (depending on the vm hardware defined)

2. Simple and quick to restore an image with the snapshots rather than using OSD to capture the “Golden Master”

3. Multiple snapshots can be created to backup and restore during various stages

4. The restore of an image can be done to any system that has VMware installed, as long as the hardware is setup the same. So the VM image can be built on Lenovo/HP/Dell/etc hardware

When using VMware, I also add the setting bios.bootdelay=15000 to the .VMX file to allow time to press the F12 key or ESC for the boot menu.

Before starting on this, one big note is around the Built-in Administrator name that is used. When installing Windows 7, you are prompted to create an id that will be an administrator on the system. When this user is created, it will be added to the Administrators group and the Built-in administrator will be disabled. In order to get the Built-in administrator enabled, you need to set the Administrator name in the OS profile to “Administrator” (has to be this no matter what you want the id to actually be). For this example, I will be changing the Built-in administrator to “myadmin” and show how to make this will work.

1. Importing Windows 7 DVD for Unattended Install

This was fairly simple. Just use the New Profile > Unattended Setup and walk through the wizard.

Info Center documentation:

http://publib.boulder.ibm.com/infocenter/tivihelp/v3r1/index.jsp?topic=/com.ibm.tivoli.tpm.osd.doc/deploy/tosd_createunattended_win.html

2. Preparing the OS Configuration for Unattended Install

Once the import is complete, open the OS configuration, go to the Windows tab and set the "Administrator Name:" field to Administrator. Also verify that the time zone is set. If you are using volume licensing, then select the “Volume licensing” option. If not, then set the serial number.

3. Deploying the Unattended Install

After the unattended install system profile is created, it can be deployed to a target system in order to create the clone profile. The methods to deploy an unattended or cloned profile are exactly the same. The big difference is the time for installation. The unattended install is significantly longer to complete than a cloned image.

Info Center documentation:

http://publib.boulder.ibm.com/infocenter/tivihelp/v3r1/index.jsp?topic=/com.ibm.tivoli.tpm.osd.doc/deploy/tosd_startdeployment_win.html

4. Customizing Master Image

There are many options to configure in the image such as included software, user ids, local policies, etc. Also remember that software modules can be used to customize an image after deployment, so make sure what is included will not require you to make more updates to the image than necessary.

Some of the deciding factors for what to do in the image vs in a software module:

- will the software take too long to deploy in a software module. For example:

- MS Office, this product takes a very long time to run through installation than it does to have included in the image

- Adobe Flash, this product is quick to install but is updated quite regularly, so it is probably better to have in a software module.

- Antivirus applications. Since these are core to protecting the corporate environment, they should be in the image. This is because there could be a failure installing the software module which would end up leaving a system unprotected.

The Windows 7 image is quite large even without any software installed, so whatever can be cleaned to minimize this image would be a good idea. Typically I would include any patch backups as this could shrink an image by 1GB or more.

As stated, I have changed my Administrator (SID 500) account to myadmin. This is a typical configuration that most sites will do. There are a couple “quirks” that happen when you do this:

  1. After the change, the user directory on the system will be C:\Users\Administrator. When you deploy the image, the directory will be changed to C:\Users\myadmin. You cannot change the directory name on the original image (you can Google it).
  2. As stated earlier, when setting the OS Configuration in step 7, you have to set the Administrator Name to “Administrator”. If you do not, the system will be deployed with the “myadmin” account, but it will not be the SID 500 account, it will just be an id in the Administrators group. The SID 500 will be called Administrator and it will be disabled. When set correctly, the “myadmin” will be the SID 500 account and another account called “Administrator” will be added to the Administrators and Users groups. For my deployment, I included a software module that would remove it from both groups and disable the account.

Another issue that I ran into was that I deleted the C:\install directory. This is created by the unattended install. When deploying an image to the target, the c:\install directory would be created, but when executing software modules later in the build process, they would not execute. This is being addressed in a future fix (not in FP04). To workaround this issue, just leave the c:\install directory in the image.

5. Executing sysprep

Once the unattended install is complete, the system can then be configured with any corporate software and configurations. After all configurations are completed, the next step is to use the Microsoft tool called Sysprep. This tool is used to remove system specific configurations to allow for a cloning of an image to different systems.

http://technet.microsoft.com/en-us/library/cc783215%28WS.10%29.aspx

Unlike Windows XP, sysprep is already on Windows 7 and is located in C:\Windows\System32\Sysprep. The options selected are OOBE, Generalize and Shutdown. I prefer using the shutdown as I do not want to miss the reboot and have the mini-setup run again.

Info Center documentation:

http://publib.boulder.ibm.com/infocenter/tivihelp/v3r1/index.jsp?topic=/com.ibm.tivoli.tpm.osd.doc/deploy/tosd_ref-compwinvista.html

Notes:

A system that is joined to a domain cannot be used for creating a cloned profile. If the system has been joined to a domain, then it has to be moved to workgroup mode.
- Some extra recommended tasks are:
- Empty recycle bin
- Execute chkdsk to ensure there are no disk error
- Clean out temporary files
- Remove any persistent drive mappings
- Clear the Application, Security and System event logs
- Sysprep still has the limit of being executed 3 times in Windows 7.

6. Capture Clone Image

Capturing the Windows 7 OS is no different than the methods used for any other operating system. The process is quite a bit longer than Windows XP and requires more reboots, but overall the whole process is the same.

Info Center documentation: http://publib.boulder.ibm.com/infocenter/tivihelp/v3r1/index.jsp?topic=/com.ibm.tivoli.tpm.osd.doc/deploy/tosd_clone_win.html

7. Modifying the OS Configuration for Clone Install

Once an image is imported, the OS configuration will need to be set. The OS Configuration is where you use OSD to set the parameters that will be used in the unattend.xml file. The UI will allow for the configuration of many of the common settings, but if there are more that are required, use the “Edit custom unattend.xml” on the General tab. When setting the OS configuration, the most important item to set is the “Administrator Name” to “Administrator”. This is done by opening the properties for the OS configuration and going to the Windows tab. Also on this tab in the “System Customization”, check the setting “Always authorize installation of unsigned drivers”.

8. Deploying the Cloned OS

Deploying the Windows 7 OS is no different than the methods used for any other operating system. The process is quite a bit longer than Windows XP and requires more reboots, but overall the whole process is the same. One thing that did happen in Windows 7 and not XP is that OSD actually logs into the OS. This causes some issues with scripts that may be in the run/runonce/startup.

Info Center documentation:

http://publib.boulder.ibm.com/infocenter/tivihelp/v3r1/index.jsp?topic=/com.ibm.tivoli.tpm.osd.doc/deploy/tosd_clone_win.html

Other Notes:

TPMfOSD started supporting Windows 7 in 7.1.1.1, but this version and 7.1.1.2 use the WinPE2. There are some pretty significant improvements in using 7.1.1.3 or better yet 7.1.1.4 as it utilizes WinPE3 for the deployments. If you have not started, or are just starting, then move to one of these versions. There are other reasons for moving to these newer versions, but this is one of the most visible from a deployment perspective.

Conclusion

As noted, this is a fairly high level of using OSD for Windows 7 deployments, but should start you on the right path.

GbsTask - A Task Management Utility for ITM

Introduction
In Tivoli Management Framework, there is a concept called "Task". Tasks let users to specify executable for a specific platform at the creation time. When a task is run against multiple targets ("endpoints"), the appropriate executable is transferred and executed on the remote system and the output is presented in the standard output. When executed on multiple targets, the execution is done in multi-threaded manner.

We, at Gulf Breeze, developed a Java based solution to implement the task feature in Tivoli Monitoring product and this article discusses about this solution in detail. If you are interested, please email me and I will send you a free copy.

Benefits
  • A Simple database driven tool to create/update/delete/execute tasks.
  • Tasks can be executed on individual OS agents or on ITM MSLs.
  • Tasks can be executed in a multi-threaded manner across agents of different platforms.
  • Supports SQLServer or DB2 databases to store task information.
  • Authorization information kept in a separate file and can be specified with -a switch. You don't need to specify the password in your scripts.
Limitations
  • Maximum number of threads is limited by the maximum number of "tacmd"s that can be run in parallel. Running more than this limit could cause stability issues. As of ITM 6.2.2. FP2, the maximum number of threads is 10.
  • Currently the tasks can be executed only against Windows, Linux and Unix OS agents.
Requirements

To run the "gbstask" solution, you will need the following. The solution is tested with SUN JRE 1.5 and "should" work in other implementations of Java Runtime.
  • JRE 1.5 or later. (The code will NOT work with JRE 1.4).
  • JDBC driver for your database.
  • Tacmd CLI. (The CLI is installed with an OS agent installation or ITM TEMS installation).
  • A SQL Server or DB2 database where you can create a table to contain task information.
Examples

The following command creates task called pingtask for Linux and Windows.
# Creates tasks for Linux and Windows
C:\temp>java -jar GbsTask.jar -a db2.auth -c -l mylib -t pingtask -o Linux -f C:\temp\test.sh
C:\temp>java -jar GbsTask.jar -a db2.auth -c -l mylib -t pingtask -o Windows -f C:\temp\test.bat
# Executes a task on specific managed systems.
$ java -jar GbsTask.jar -a db2.auth -x -l mylib -t pingtask -h Primary:VMTBSM421:NT,vmitm622:LZ,Primary:VMTBSM42X:NT
# Executes a task on specific MSLs.
$ java -jar GbsTask.jar -a db2.auth -x -l mylib -t pingtask -m "*NT_SYSTEM,*LINUX_SYSTEM"
# Deletes a task
$ java -jar GbsTask.jar -a db2.auth -d -l mylib -t pingtask -o Windows
$ java -jar GbsTask.jar -a db2.auth -d -l mylib -t pingtask -o Linux


Sample Output

$ java -jar GbsTask.jar -a db2.auth -x -l mylib -t pingtask -h Primary:VMTBSM421:NT,vmitm622:LZ,Primary:VMTBSM42X:NT

Adding a custom Java portlet to the TIP for use with WebTop, WebGUI, TBSM, etc.

REMOVED


This article has been removed because it worked for very specific versions of products, but not for the latest versions, and customers were calling Tivoli support to open PMRs when it didn't work. If you're trying to add a portlet, this is CUSTOM work, for which you should not open a PMR.

So I'll revisit this issue when I have time to test with the latest and greatest versions. Until then, if you would like the article, you can send me an email at frank dawt tate aat gulfsoft dot com.
